Texto completoAtherosclerosis, once considered a disease mainly linked to accumulation of lipids within the inner tunic, is now recognized as a chronic inflammatory degenerative process with a multifactorial etiology that, even if occurs clinically in adults, shows prognostic signs at an early age. Our study, performed on patients enrolled after acute myocardial infarction with ST elevation (STEMI) undergoing primary coronary angioplasty, aims to assess the role of the immune system modulation during the atherosclerotic plaque rupture due to myocardial infarction. Preliminary data, showed a massive presence of IFN-γ, IL-17 and IL-21 in coronary arteries affected by lesion compared to those exempt and to peripheral arteries. The high levels of cytokines observed in damaged arteries are not due to the increase in the number of leukocyte cells present, but are due to activation of the same cell and expression of their cytokine pattern. Moreover, in the acute myocardial infarction the serum levels of pro-inflammatory factors such as IL-6 and anti-inflammatory such as IL-10 increased. However, the increase of IL-6 was significantly higher than that of IL-10. After a month of the injury, the observed serum levels of IL-6 and IL-10 are balanced. In our view, the main activity of pro-inflammatory factors is relevant in the progression of the lesion and in the development of complications associated with acute myocardial infarction.

Texto completoDespite a gradual increase in health investment, even in developed countries, the growing demand for resources has created a significant and gradually increased deficit. The rise in health costs therefore represents a challenge for government and private payers. Even with the increased longevity of the population, most of this spending appears to be the result of the development and diffusion of new medical technologies applied at all stages of health care (diagnosis, prognosis, therapy and prevention). Atherosclerotic coronary artery disease (CAD), resulting from obstruction of the coronary arteries is a major cause of disability and death in the world today. A projection for 2020 puts these pathologies as responsible for 25 million deaths a year. Besides drug treatment, some patients with this disease will benefit from some type of mechanical intervention. Percutaneous transluminal coronary angioplasty (PTCA) is a technology used to restore flow in clogged coronary arteries, dilating regions of narrowing of these vessels. This technology was initially used as an alternative for patients who should undergo coronary artery bypass graft (CABG) surgery. In the last three decades, with technological advances, PTCA spread rapidly, with an expansion of candidate population for this technology, promoting changes in the treatment of coronary atherosclerosis. The objective of this work is to review and discuss the evidence related to the diffusion of PTCA, trying to identify factors as potential determinants of diffusion and its consequences. We performed a literature search of evidence on the introduction and diffusion of PTCA also considering review articles, editorials and discussion on the subject. A manual review of abstracts of each article was done later, prioritizing items obtained inside of CAPES journals site. It is hoped that better understanding of this technology diffusion may help in better resource allocation and formulation of health policies.

Texto completoBACKGROUND.- Percutaneous coronary intervention has shown to be effective in patients with acute coronary syndromes (ACS). However, due to in-stent restenosis, the rate of clinical events in patients with ACS still remains high. Drug eluting stents (DES) have shown to reduce in-stent restenosis and target lesion revascularization, but its results in ACS population are controversial.OBJECTIVES.- To confirm whether DES are safer and more effective than bare metal stents (BMS) in patients with ACS. We considered clinical and angiographical objectives. The clinical primary end-point was the incidence of target lesion revascularization (TLR) at 1 year. Clinical secondary end-points were major adverse cardiac events (MACE) and the incidence of stent thrombosis at 1 year. An angiographic follow-up was performed from 1 year. The angiographic primary end-point was the incidence of in-stent restenosis.METHODS.- We conducted an observational study of 145 patients with ACS who were treated with DES. This group was compared with 138 patients treated with bare metal stents (BMS) in the preceding period.RESULTS.- The procedure was successful in all patients. At 1 year, the incidence of TLR was lower in the DES group than in the BMS group (7,6% vs. 19,6%, respectively; p=0,003), as were the rates of MACE (11,7% vs. 27,5%; p=0,001). There was no significant difference between the two groups in the rate of death (2,1% vs. 6,5%; p=0,06), myocardial infarction (3,4% vs. 2,1%;p=0,36) or stent thrombosis (2,1% vs 2,2%, respectively;p=0,82). In the angiographic follow-up the rate of in-stent restenosis was also lower in the DES group (13,7% vs. 33%; p=0,001) due to a lesser late luminal loss (1,94+0,91 vs 2,40+1,90;p=0,02).CONCLUSIONS.- In patients with ACS, implantation of DES is as safe as BMS. DES reduce the incidence of TLR and MACE at 1 year, and shows better angiographic results on the follow-up, reducing in-stent restenosis by 58% and late luminal loss by 64%. Angiographic pattern of in-stent restenosis was, more often, focal in DES and diffuse in BMS. No significant differences were seen in death, myocardial infarction or stent thrombosis. Stent thrombosis was related with ST elevation myocardial infarction procedures and larger stent length.

Texto completoA pesar de las mejoras en los resultados y en la técnica de los procedimientos de revascularización percutánea coronaria, existen pocos estudios que validen los resultados clínicos de la aplicación de los nuevos diseños de stents, las características de la lesión y los fármacos empleados.
En nuestro estudio, los objetivos principales son los siguientes:
1. Evaluar los resultados del stent estudiado (NIR). Confirmar la influencia de los factores de riesgo coronario sobre la evolución de los pacientes tratados con stent, determinar la influencia de las características propias de la lesión y de las variables del procedimiento.
2. Determinar la influencia de los diferentes fármacos empleados en los pacientes a los que se ha implantado un stent coronario.
Hipótesis:
1- Procedimiento
El stent empleado representa el prototipo de los stents de segunda generación y debe ofrecer ventajas respecto a los stents de primera generación (Palmaz), por lo que se le supone una elevada tasa de éxito angiográfico (definida como adecuada implantación del stent con una estenosis residual < 30% por estimación visual); una elevada tasa de éxito clínico de implantación (definido como consecución de éxito angiográfico junto a la ausencia de complicaciones mayores durante la hospitalización); una tasa reducida de MACE (MACE fue definida como muerte, IM o revascularización coronaria por ACTP o Pontaje quirúrgico) y una tasa reducida de restenosis angiográfica (definida como la presencia en el segmento previamente tratado de una estenosis > 50% en cualquier coronariografía durante el seguimiento).
Las mejoras en el diseño del stent estudiado (paradigma de los llamados de segunda generación) permitirán reducir la curva de aprendizaje y en casos seleccionados la implantación sin predilatación previa.
2- Influencia de fármacos
Los pacientes con enfermedad coronaria, que precisan la implantación de un stent, son sometidos a distintos tratamientos farmacológicos: Durante la intervención, durante el primer mes y de forma crónica. Nuestra segunda hipótesis es que los tratamientos farmacológicos se indican por situaciones clínicas y factores de riesgo, y que estos tratamientos ejercen alguna influencia positiva en la evolución de los pacientes.
Pacientes y métodos
Entre agosto de 1997 y octubre de 1998, fueron incluidos en este estudio 1.004 pacientes (cada centro incluyó a un máximo de 25 pacientes con un total de 1.136 lesiones tratadas). El diseño del estudio fue prospectivo multicéntrico con un total de 50 centros participantes de España y Portugal. El anagrama del estudio fue ESPORT NIR (ESPaña y PORtugal registro NIR stent ).
Todos los pacintes fueron sometidos a seguimiento clinico durante siete meses.
Del total de 1004 pacientes incluidos se seleccionó una muestra aleatoria de 210 enfermos consecutivos (239 lesiones) para una reevaluación angiográfica a los 6 meses de la ACTP. Además, se realizó una angiografía durante el periodo de seguimiento (a los 6 meses o antes) a cualquier paciente incluido en el estudio con recurrencia de la isquemia. En estos pacientes se realizó cuantificación de la estenosis residual mediante evaluación angiográfica automática cuantitativa con el sistema MEDIS 4,0 CMS, en un laboratorio central y por técnicos expertos no participantes en los procedimientos de ACTP. Las películas de angiografía debían seguir un riguroso protocolo, que incluyó la recogida del segmento distal del catéter utilizado.
Resultados
La edad media de los pacientes fue de 60 años y el 82% eran varones. La indicación de la angioplastia fue angina inestable en el 61% de los casos. El éxito angiográfico fue del 99% y el éxito clínico del procedimiento del 98%. La restenosis angiográfica fue del 16% (IC del 95%, 11,7-21,2). La tasa acumulada de eventos mayores al séptimo mes de seguimiento fue del 8,7%: un 0,9% de fallecimientos, un 1,2% de infartos de miocardio y un 6,6% de revascularizaciones sobre el vaso tratado.
Conclusiones
1. Stent NIR en el tratamiento de lesiones coronarias
1.1. El tratamiento de lesiones coronarias significativas con el stent estudiado muestra:
1.1.1. Elevado éxito angiográfico (99,6%; definido como adecuada implantación con una estenosis residual < 30% por estimación visual)
1.1.2. Elevado éxito clínico de implantación (98,7%; definido como consecución de éxito angiográfico junto a la ausencia de complicaciones mayores durante la hospitalización).
1.2. Tras siete meses de seguimiento desde la implantación del stent coronario:
1.2.1. La incidencia de acontecimientos cardiacos mayores (MACE) es baja (8,7%; definidos como muerte, IM o revascularización coronaria por angioplástia o pontaje quirúrgico).
1.2.2. La tasa de restenosis angiográfica de las lesiones tratadas es baja (16,32 %; definida como la presencia, en el segmento previamente tratado, de una estenosis > 50% en cualquier coronariografía durante el seguimiento). Son predictores independientes de reestenosis la diabetes y la longitud de los stents
1.3. Influencia de la técnica de implantación y del seguimiento
1.3.1. La experiencia en stents del centro de intervención no da lugar a diferencias en las tasas de éxito angiográfico o clínico de implantación o en la incidencia de MACE o reestenosis.
1.3.2. Los pacientes con seguimiento angiográfico tienen un exceso de revascularización en comparación a los que siguen un control clínico.
1.3.3. En casos seleccionados, la utilización de stent sin predilatación no da lugar a diferencias en el éxito angiográfico, clínico, MACE o restenosis,
2. Influencia de fármacos en la angioplastia con stent
2.1. Fármacos indicados por protocolo:
2.1.1. El tratamiento con ticlopidina reduce el riesgo de MACE al primer mes.
2.1.2. El tratamiento con AAS reduce el riesgo de MACE al primer mes en los pacientes diabéticos. El tratamiento mantenido se asocia a una reducción del riesgo de MACE para toda la población estudiada.
2.2. Fármacos electivos:
2.2.1. La administración de abciximab es más frecuente en pacientes con antecedentes de infarto agudo y se asocia a una mayor incidencia de MACE aguda.
2.2.2. Se adminitra IECA a una población de más edad, HTA, IM previo, angioplastia previa e insuficiencia ventricular izquierda. Sin embargo, no aparece un incremento de MACE en ninguno de los subgrupos estudiados.
2.2.3. Se administran betabloqueantes a una población de mayor indencia de IM previo, HTA y lesiones más graves. A pesar de ello, el grupo tratado no muestra mayor incidencia de MACE que la población que no precisó este tratamiento.
2.2.4. Se trata con calcioantagonistas una población con mayor incidencia de diabetes, IM previo y angina. Sin embargo, el grupo tratado no muestra un incremento MACE.
2.2.5. Se administran estatinas a una población con más dislipemia y diabetes. Los pacientes tratados muestran una incidencia de angina superior, aunque no un mayor riesgo de MACE o de restenosis angiográfica.
2.2.6. Se trata con nitritos a una población de pacientes con mayor incidencia de HTA, diabetes y angina. Solo aparece un aumento en la incidencia de MACE en los pacientes tratados con dislipemia. La tasa de restenosis es mayor en los pacientes diabéticos tratados con nitritos.

Texto completoBackground - Overproduction of extracellular matrix, cellular proliferative events and morphologic remodelling of vessel wall, derived mainly from inapropriate activity of smooth muscle cells and macrophages, are key features in the pathophysiology of restenosis post coronary angioplasty. Several cytokines are known to be involved in the regulation of those cell functions but their exact role in the overall process remains to be defined, due to the lack of a method capable of sequential assessment over time. In this study, we sought to investigate the leveis o f circulating markers o f immunoinflamatory activity in patients with restenosis, to test the hypothesis that they are elevated when compared with patients with primary atherosclerosis and healthy volunteers. Objective- To compare the expression of interleukin 2 soluble receptor (sr-IL2), tumour necrosis factor (TNFu), soluble receptor I and II of tumour necrosis factor (sr-I TNFu and sr-II TNFa) and interleukin 1 beta (IL-lP) in periferic blood of patients with restenosis, primary atherosclerosis and healthy volunteers. Methods - Eleven patients with coronary restenosis post angioplasty and 1 O patients with primary atherosclerosis referred for coronary arteriography were studied. Ten normal volunteers without coronary artery disease or risk factors for its presence served as controls. Blood samples were drawn and processed immediately before coronary arteriography and plasmatic concentrations of fí:-IL2, TNFu, sr-I TNFa, sr-II TNFa and IL-1 P were analised by an ELISA method. Results were compared by ANOVA. Results - There were no significant differences in age, sex, risk factors for coronary artery disease and treatment in both groups of patients. The group of patients with coronary restenosis had more vessels involved in angiography and shorter time between the last episode of angina and blood sampling. Plasmatic leveis of sr-IL2 were significantly greater in restenosis patients (1640 ± 576 pg/ml) than normal indiviuals (796 ± 470 pg/ml), but smaller than patients with atherosclerosis (2283 ± 542 pg/ml) (p<0.05). There were no differences between TNFa and its soluble receptors leveis in coronary restenosis patients (sr-I TNFa=1021 ± 108 pg/ml; sr-II TNFa=2267 ± 447 pg/ml; TNFa=O pg/ml [0-2.8 pg/ml]) and normal individuais (sr-I TNFa= 888 ± 162 pg/ml; sr-II TNFa=2123 ± 345; O pg/ml [0-0.3 pg/ml] ) but primary atherosclerosis patients displayed leveis significantly greater than both groups (sr-I TNFa= 1223 ± 194 pg/ml; sr-II TNFa= 2958 ± 716 pg/ml; TNFa= 0.65 pg/ml [0-3.0 pg/ml]). IL-113 leveis were undetectable in all subjects. There was no correlation between the severity of coronary artery disease and time to last episode of angina with the leveis of each cytokine. Conclusions - Coronary restenosis patients present greater leveis of sr-IL2 but not of TNFa or its soluble receptors when compared with normal individuais. Primary atherosclerosis patients present greater leveis of ali this markers when compared Vvith either restenosis patients or normal individuais. These results point to moderate linfocitary activity in coronary restenosis patients and more significant immunoinflammatory activity in patients with primary atherosclerosis.

Resumo: Processo de reestenose, a proliferação neointimal parece estar associada à carga de placa inicial de acordo com estudos utilizando o ultrassom intravascular (IVUS). O objetivo deste estudo foi avaliar a relação entre a placa inicial e a proliferação neointimal após implante de stent coronário, não recoberto, pela angiografiacoronária quantitativa (ACQ). Métodos: De junho de 1997 a junho de 2000, 26 pacientes consecutivos, 61% do sexo masculino, 35% diabéticos foram submetidos a cinecoronariografia com 21 a 586 dias após implante de stent coronário, com suspeita clínica de reestenose intra-stent. Para a análise dos angiogramas coronários, escolheu-se como centro dos segmentos analisados o locus médio do stent. Nós avaliamos: (1) a distribuição da proliferação neointimaltotal (PNT), da proliferação neointimal vinculada à placa (PNVP), da placa inicial (PI) e a confluência da placa inicial com a proliferação neointimal total ao longo dos contornos superior e inferior do vaso; (2) a área de proliferação neointimal total (APNT), a área da placa inicial (API) e suas confluências. Resultados: A análise de regressão linear univariada mostrou uma significativa correlação entre PNT e PI (r=0,66, p=0,0002) e uma forte correlação entre PNT e PNVP (r=0,89, p=0). Análise de regressão univariada mostrou uma significativa correlação entre APNT e API (r=O,63, p=0,0005) e uma maior correlação entre APNT e APIC (r=0,87, p=0). Não existiu diferenças significativas nos resultados da análise de regressão entre os níveis binários dos fatores sexo, reestenose e diabetes. Conclusão: Nosso estudo suporta o conceito de uma significante associação entre a proliferação neointimal que ocorre após o implante de stent e a placa inicial
Abstract: In the process of restenosis, neointimal proliferation appears to be associated with initial plaque, according to intravascular ultrasound studies. The purpose this study was to assess the relationship between initial plaque and neointimal proliferation afier stent implantation using quantitative coronary angiography (QCA). Methods: We select the data fi:om 26 patients, 61 % males, 35 % diabetics, who had a second coronary angiogram done fi:om 21 to 586 days afier stent implantation for diagnostic investigation of chest pain. Coronary angiogram of same angiography views were analyzed taking the center of the image of the stent as common topographic 1andmark. We assess: (1) the distribution of abnormalities in the contours along the 10ngitudinal1engthof the image correspondent to the neointimal proliferation (NP) and to the initial plaque (IP), and the distribution of initial p1aque confluent (IPC) with the distribution of neointimal proliferation; (2) the area of neointimal (ANP), the area of initial plaque (AIP) and the area ofplaque confluent with the neointimal area (AIPC). Results: Univariate linear regression analysis showed a significant correlation between NP and IP (r=O.66, p=O.OO2)and strong correlation between NP and IPC (r=O.89, p=O). Univariate linear regression analysis showed a significant correlation between ANP and AIP (r=O.63,p=O) and a strong correlation between ANP and AIPC (r=O.87,p=O). There was no significant difference in results of regression analysis between the binary levels of the factors seXorestenosis and diabetes. Conclusion: Our study support the concept of a significant association between initial plaque and neointimalproliferation growth afier implantation of coronary stents

Approximately 5% of patients with acute myocardial infarction under the age of 45 years. The specific characteristics, clinical and epidemiological this population are not well understood. The aim of this study is to characterize the clinical, epidemiological and coronary cineangiography in young people undergoing primary coronary angioplasty (PTCA). We performed a retrospective analysis of 150 medical records of patients under the age of 45 years who underwent PCI between January 2006 and December 2010. We analyzed the risk factors, clinical presentation and electrocardiographic left ventricular function, characteristics of the coronary anatomy, medical treatment and hospital course. It was observed that the average age of patients was 40.1 ± 5 years, predominantly male (68.7%). The risk factors associated with AMI were smoking (65%), hypertension (50%), family history of coronary artery disease (40%) and low levels of HDL - cholesterol (60%). The prevalence of diabetes mellitus was 19.3%. Involvement of the anterior descending artery (AD) occurred in 53% of individuals and 75% was observed in the disease in a single vessel. The average time of arrival at the hospital after symptom onset (delta T) was 5.5 ± 3.4 hours and hospital stay was 10.36 ± 14.1 days. In 58% of patients, the ejection fraction of left ventricle was greater than 55%. There was one death. The success rate of PTCA was 91%. Regarding the treatment of AMI patients received aspirin overall (99.3%), clopidogrel (98%), angiotensin-converting enzyme inhibitors (ACEI) (85.3%), beta blockers (66%), statins ( 97.3%) and prescription of glycoprotein IIb-IIIa was observed in only 10% of patients. We conclude that in young AMI presents itself as an entity typically masculine and good prognosis in early evolution, provided that appropriate treatment instituted in a timely manner. Medical treatment for these patients at the Hospital of Messejana Dr. Carlos Alberto Studart Gomes contemplates what is proposed by the IV Brazilian Guideline for the treatment of AMI with ST-segment elevation.
Aproximadamente 5% dos pacientes com infarto agudo do miocárdio têm idade inferior a 45 anos. As características específicas, epidemiológicas e clínicas desta população ainda não estão bem esclarecidas. O objetivo do presente estudo é caracterizar a apresentação clínica, epidemiológica e cinecoronariográfica em jovens submetidos à angioplastia coronariana primária (ATC). Foi realizada uma análise retrospectiva de 150 prontuários de pacientes com idade inferior a 45 anos submetidos à ATC entre janeiro de 2006 e dezembro de 2010. Foram analisados os fatores de risco, a apresentação clínica e eletrocardiográfica, a função ventricular esquerda, características da anatomia coronariana, o tratamento médico e a evolução hospitalar. Observou-se que a idade média dos pacientes foi de 40,1 ±5 anos, com predominância do sexo masculino (68,7%). Os fatores de risco mais associados com o IAM foram o tabagismo (65%), a hipertensão arterial sistêmica (50%), a história familiar de doença arterial coronariana (40%) e os baixos níveis de HDL - colesterol (60%). A prevalência de diabetes mellitus foi de 19,3%. O acometimento da artéria descendente anterior (DA) ocorreu em 53% dos indivíduos e em 75% foi observada doença em uma única artéria. O tempo médio de chegada ao hospital após o início dos sintomas (delta T) foi de 5,5 ± 3,4 horas e a permanência hospitalar foi de 10,36 ± 14,1 dias. Em 58% dos pacientes, a fração de ejeção do ventrículo esquerdo foi superior a 55%. Houve apenas um óbito. A taxa de sucesso da ATC foi de 91%. Quanto ao tratamento do IAM, os pacientes receberam globalmente ácido acetilsalicílico (99,3%), clopidogrel (98%), inibidores da enzima de conversão da angiotensina (IECA) (85,3%), betabloqueadores (66%), estatinas (97,3%) e a prescrição de inibidores da glicoproteína IIb-IIIa foi observada em somente 10% dos pacientes. Concluímos que o IAM em jovens apresenta-se como uma entidade tipicamente masculina e de bom prognóstico na evolução precoce, desde que instituído tratamento adequado em tempo hábil. O tratamento médico destinado a estes pacientes no Hospital de Messejana Dr. Carlos Alberto Studart Gomes contempla o que é proposto pela IV Diretriz Brasileira para tratamento do IAM com supradesnivelamento do segmento ST.

Texto completoThis descriptive study was developed by mens of the case study method, of various cases, focusing the anxiety phenomena. Goals: identify the presence and qualify the level of anxiety in ischemic cardiac patients before and after (ten minutes) giving out instructions about the procedure of the percutaneous transluminal corornary angioplasty (PTCA); measure the level of anxiety of these clients ten minutes before they entered in the procedure room for itscompletion. The Research EthicsCommittee approved this study, and data collection was performed through spontaneous demand according to researchers convenience. The sample: considered of twenty ischemic cardiac patients, all adults, which had been forwarded by the Single Health Sistem for the first PTCA proceduce. The study was compound which a structured partivipative observation and three moments for measuring arterial pressure, cardiac and respiratory frequency, and the application of Spielbergers (STAXI) State-Trait Anxiety Inventory. In the first moment there was also the application of the STAXI-Trait. Methods of simple statistical analisys were used to obtain the results. Results: showed that the sytolic arterial pressure was maintained above limit values, according to the Cardiology Brazilian Society, in all threee moments for more than 60% of the cases, anti-hypertensive treatment was performed; the observed satandarts for cardiac frequency were kept within the normality rank for 85% of the cases, however, 70% of the individuals form the sample made use of beta-blockers; the respiratory frequency showed to rise during the evolutionof the moments. With increased respitation rate in 50% of the cases in the second moment and 70% in the third. The values, according to the score and categorization of STAXI, had the measures of state of anxiety in a moderate rank in the three moments, being that there was a variation between the sencond and third moments of up to approximately six points, whichled some clientsto wrong level. For trait anxiety, the rank was also moderate. The nursing instructions were performed by five different professionals and produced an increase of STAXI pontuaction in 60% of the clients. This was obseved and reported by someas an increase of nervousness after the instruction. The content of the observations shows that the characteristic behaviors related to anxiety were maintained in all clients, with a higher number and variety disproportional to the waiting time. The study allows us to conclude that the anxiety caused by PTCA is already altered (moderate), and is kept at this level or worsens during the waiting period, and the nursisng instructions do not make this anxiety decrease, and, in some cases, it even increase. Despite using anti-hypetensive medication, the clientdevelop slight to severe hypertension accompained by an elevation of respiratory frequency and maintenance of cardiac frequency at normal rates from the first to the third moment. The environment to which the individual is exposed contributes to the manifestation of anxiety, worsening it was well. The studys sample is considerate to be small, allowing only the naturalistic generalization. The realy experienced by cardiac patient has been exposed, raising new questionings and showing the need for local environmental interventions. It is hoped to, throught this study, incite new studieswith larger populations, increasing the comprehension of anxiety.

Cardiovascular diseases remain as the leading cause of death worldwide, especially the coronary artery disease. Percutaneous transluminal coronary angioplasty (PTCA) is one of the most commonly used methods for treating such disease. Technological advances have made possible to perform safer procedures with reduced stay in the hospital. However, educational interventions are still needed concerning modifiable risk factors that lead to behavioral changes, treatment adherence, and better quality of life in terms of health. This study aimed at assessing the quality of life in terms of health in patients submitted to percutaneous transluminal coronary angioplasty by using the variables of the SF-36 questionnaire and developing leaflets on coronary angioplasty and healthy lifestyles. Forty-five patients hospitalized in Botucatu Medical School Hospital – UNESP who were undergoing the procedure for the first time were included in the study. The data collection occurred twice from January to May 2012. The patients were evaluated regarding their quality of life before the coronary angioplasty (M1) and from 30 to 40 days after it (M2). Leaflets on PTCA and healthy lifestyles were designed to assist guiding such patients. The participants were in average 60.8 years old, mainly male (60%), and had low educational backgroun (in average, 5.1 years of study). Among the key risk and comorbidity factors were systemic hypertension (77.8%), sedentarism (71.1%), and dyslipidemia (60%). The average scores of the SF-36 were higher at M2, with statistically significant differences in all domains except in the Emotional Aspects. The patients related that the guidance offered, together with the leaflets, were highly important because not only did they clarify many doubts, but they also aided in several changes in their health habits, such as reduction in their intake of deep-fried foods/fatty meat (53.3%) and reduction of salt in their food ...

Objective: to estimate the Health Related Quality of Life (HRQoL) and the level of Anxiety in individuals that were submitted to percutaneous transluminal coronary angioplasty (PTCA), as well as variables associated with better HRQL and lower anxiety. Method: This was a cross-sectional study with individuals of age 18 to 81 years old who underwent PTCA in 2012 at Goiânia, Goiás. The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to assess the Health Related Quality of Life (HRQoL), which is composed of a physical (PC) and a mental component (MC), each with four domains. Anxiety symptoms were assessed by the Beck Anxiety Inventory (BAI); other variables obtained through a sociodemographic questionnaire. The association between sociodemographic variables and outcomes (quality of life and level of anxiety) was estimated by univariate analysis using the t test or ANOVA. P values <0.015 were considered statistically significant and included in the multivariate linear regression model. Results: 169 patients were included, the majority was male (61.0%) and the average age was 65.3 years (sd ±10.2). The highest scores of HRQL were observed on the physical domain of SF-36. The following variables were independently associated with better HRQoL on the physical domain: male gender, higher education, elective angioplasty, working and living with partner; mental domain: work, religious practice, private health insurance and living with partner. The lowest anxiety level was independently associated with two variables: male and have private health insurance. Conclusion: The evidences of this study suggest that better HRQoL in adults and elderly that were submitted to PTCA may be associated to professional activity, gender, age, education level type of PTCA realized.
Objetivo: Analisar a qualidade de vida e o nível de ansiedade em indivíduos submetidos à angioplastia coronariana e fatores relacionados. Método: Foi realizado estudo de corte transversal com indivíduos de 18 a 81 anos submetidos a AC em 2012 no município de Goiânia, Goiás. Para avaliar a Qualidade de Vida Relacionada à Saúde (QVRS) foi utilizado o Medical Outcomes Study 36-item Short-form Health Survey (SF-36), composto por dois componentes: físico (CF) e mental (CM), cada um com quatro domínios. Os sintomas de ansiedade foram avaliados pelo Inventário de Ansiedade de Beck (BAI) e, aplicado questionário com dados sociodemográficos. A associação entre as variáveis sóciodemográficas e os desfechos (qualidade de vida e nível de ansiedade) foi estimada através análise univariada por meio do teste t ou ANOVA. Valores de p<0,015 foram considerados estatisticamente significantes e incluídos no modelo de regressão linear multivariada. Resultados: Foram incluídos 169 pacientes, a maioria do sexo masculino (61,0%) e a média da idade foi de 65,3 anos (SD ± 10,2). Os melhores escores de Qualidade de Vida foram observados no componente físico do SF-36. As seguintes variáveis estiveram independentemente associadas com melhor Qualidade de Vida no domínio físico: sexo masculino, maior escolaridade, angioplastia eletiva, trabalhar e morar com parceiro; no domínio mental: trabalhar, prática religiosa, plano de saúde privado e morar com o parceiro. A menor intensidade da ansiedade esteve independentemente associada com duas variáveis: sexo masculino e ter planos de saúde privado. Conclusão: As evidências deste estudo sugerem que a melhor QVRS em indivíduos adultos e idosos que se submeteram à angioplastia coronariana pode estar associada à atividade profissional, gênero, idade, escolaridade e tipo de angioplastia realizada.

Texto completoOBJETIVOS DEL ESTUDIO.- Se realizó un estudio angiográfico secuencial en una serie consecutiva de pacientes que habían sido sometidos a una angioplastia coronaria eficaz para determinar la relación existente entre la presencia inicial de reestenosis post-angioplastia y la aparición posterior de progresión en la aterosclerosis coronaria y para evaluar la evolución anatómica a largo plazo de la estenosis residual de la lesión dilatada en un grupo de pacientes sin reestenosis inicial.
MATERIAL Y MÉTODO.- Noventa y ocho pacientes en los que se realizó una ACTP eficaz sobre 110 lesiones de arterias nativas fueron incluidos en el estudio para evaluar la relación entre reestenosis post-angioplastia y progresión de la aterosclerosis.. Sesenta y tres pacientes sin reestenosis precoz fueron incluidos en un estudio angiográfico seriado para determinar la evolución en la estenosis residual post-ACTP a largo plazo.
La valoración de los cambios en la severidad de la lesión producidos mediante la angioplastia, y la evolución de la estenosis residual en los diferentes controles angiográficos fueron analizados mediante un sistema de análisis angiográfico cuantitativo. Se consideró reestenosis post-angioplastia cuando un segmento dilatado mostraba en la coronariografía de control una estenosis de una severidad igual o superior al 50 %. Se consideró que se había producido progresión de la enfermedad coronaria cuando por análisis visual se documentó una disminución +/- 20% en el diámetro del vaso que inicialmente mostraba una estenosis +/- al 50%, o una reducción +/- 30% de la luz cuando la estenosis inicial fue < al 50%. Una serie de variables clínicas, angiográficas y de procedimiento fueron evaluadas prospectivamente en cada paciente.
RESULTADOS.- Progresión de la aterosclerosis y angioplastia coronaria.- Un seguimiento angiográfico precoz fue realizado tras un intervalo medio de 5 ± 2 meses después de la ACTP. El diagnóstico de reestenosis fue realizado en 39 lesiones (35%) pertenecientes a 37 pacientes (38%). Treinta y siete pacientes con reestenosis fueron sometidos a un estudio angiográfico tardío 32 ± 10 meses después de la primera angioplastia. Cincuenta y ocho pacientes sin reestenosis fueron sometidos a un reestudio angiográfico tardío a los 34 ± 12 meses post-ACTP. Se observó progresión de la aterosclerosis coronaria en 53 segmentos de 31 pacientes (34%) después de los 18 meses post-angioplastia.
En la valoración de la relación existente entre reestenosis post-angioplastia y progresión de la aterosclerosis coronaria, se observó progresión en el estudio angiográfico tardío en 22 (38%) de los 58 pacientes sin reestenosis, en comparación a 9 (33%) de los 27 pacientes con reestenosis (p= NS). En relación al momentos cronológicos de reestenosis post-angioplastia y progresión de la aterosclerosis: En las lesiones con reestenosis, el diámetro de la estenosis aumentó desde el 35 ± 8 % hasta el 73 ± 11 % (p< 0.001) en el reestudio angiográfico inicial. Por el contrario, el diámetro de la estenosis aumentó mucho más lentamente en las lesiones con progresión, desde el 9 ± 18 % hasta el 20 ± 28 % (p< 0.001) en el reestudio inicial y hasta el 53 ± 21 % (p<0.001) en el reestudio tardío. La velocidad de empeoramiento de las lesiones expresada como cambio en el porcentaje de estenosis dividido por los meses entre estudios angiográficos, fue mucho más rápida para las lesiones con reestenosis que para las lesiones con progresión: 12.3 ± 10 %/mes versus 1.1 ± 0.7 %/mes (p<0.0001). El sexo masculino (p= 0.01), el tabaquismo )p= 0.06) y la ausencia de disección post-angioplastia (p< 0.05) fueron identificados como factores predictivos de reestenosis. Entre las diferentes variables analizadas, únicamente el antecedente de diabetes y una historia previa de infarto de miocardio mostraron diferencias significativas entre los pacientes con y sin progresión (p<0.05, y p= 0.05, respectivamente).
Nuevas estenosis adyacentes a los segmentos dilatados.-. Se observó progresión de la aterosclerosis en segmentos no dilatados en 16 (17%) de 94 vasos dilatados en comparación a 25 (14%) de 176 vasos no dilatados (p= ns). Entre los 31 pacientes con progresión de la aterosclerosis se observó progresión en 16 (48%) de 33 vasos dilatados y en 25 (41%) de 60 vasos no dilatados (p= ns).
Evolucion de la estenosis residual post-angioplastia.- En el grupo de pacientes en el que se analizó la evolución de la estenosis residual de la lesión dilatada se efectuaron controles angiográficos precoces y tardíos de seguimiento, 5 ± 1 meses y 37 ± 20 meses después del procedimiento, respectivamente. La angioplastia produjo inicialmente una disminución de la severidad de la estenosis desde un porcentaje de estenosis pre-ACTP de 72 ± 13 % hasta un porcentaje de 41 ± 14 % (p< 0.0001) inmediatamente post-ACTP. En el control angiográfico realizado a los 5 ± 1 meses post-angioplastia, la estenosis residual mostró una severidad del 31 ± 14 % (p<0.001 vs post-ACTP inmediata). Asimismo, en el control angiográfico realizado a los 37 ± 20 meses después de la angioplastia, la estenosis había experimentado una nueva reducción hasta una severidad del 23 ± 15 % (p<0.001 vs post-angioplastia inmediato y p<0.001 vs 5 meses).
El análisis multivariado de regresión logística por pasos identificó que el empleo durante el procedimiento de una elevada relación entre los diámetros balón/arteria (p= 0.001), la ausencia de diabetes mellitas (p= 0.008) y la presencia del antecedente de hipertensión arterial (p= 0.01) fueron predictores de la reducción producida en la estenosis residual.
CONCLUSIONES: La aparición de la reestenosis post-angioplastia es un fenómeno independiente de la progresión de la arteriosclerosis coronaria. La instrumentalización realizada en los vasos coronarios durante la angioplastia, no acelera el desarrollo de lesiones ateroscleróticas en la arteria dilatada.
Un número significativo de pacientes con lesiones coronarias que han sido dilatadas de forma eficaz mediante angioplastia y que no presenta reestenosis en el control angiográfico inicial muestran, durante el seguimiento posterior, una progresiva reducción en la severidad de la estenosis residual.
"ATHEROSCLEROSIS PROGRESSION AND EVOLUTION OF THE RESIDUAL STENOSIS AFTER CORONARY ANGIOPLASTY: LONG-TERM ANGIOGRAPHIC STUDY"
ABSTRACT:
BACKGROUND.- The major limitation of coronary angioplasty (PTCA) is the problem of restenosis. The fibrocelular response is the principal mechanism of restenosis and is also the main component of the development of atherosclerotic lesions. Furthermore, the long-term evolution in the residual estenosis in patients without early restenosis in not completely known.
STUDY OBJECTIVES.- To determine the relationship between early restenosis post-PTCA and the long-term atherosclerosis progression, an angiographic study was performed in a series of consecutive patients who underwent a successful PTCA. In the same cohort of patients, the long-term evolution of the residual stenosis was evaluated.
METHODS.- Ninety eight patients whom underwent a successful PTCA were included to evaluate the relationship between restenosis and progression, and 63 patients, without early restenosis, were included in a sequential study to determine the long-term evolution of the residual estenosis post-PTCA. Changes in the stenosis severity were analysed by quantitative coronary angiography. Restenosis was defined as a stenosis +/- 50 % during the follow-up. Atherosclerosis progression was defined as a more 20% decrease in the diameter of a vessel initially narrowed by +/- 50% or a +/- 30% decrease when the initial stenosis was < 50%.
RESULTS.- Atherosclerosis progression and coronary angioplasty.- An early angiographic follow-up was performed 5 ± 2 months after angioplasty. Restenosis was documented in 37 patients (38%). These patients were again angiographically evaluated 32 ± 10 months post-PTCA. A new angiographic study was performed in 58 patients without restenosis, 34 ± 12 months post-procedure. Coronary progression was observed in 53 segments from 31 patients (34%) more than 18 months post-angioplasty.
In the evaluation of the relationship between restenosis post-angioplasty and atherosclerosis progression, long-term progression was documented in 22 (38%) of the 58 patients without restenosis, in comparison to 9 (33%) of 27 patients with restenosis (p= NS).
Long-term evolution of the residual stenosis post-angioplasty.- In the group of patients evaluated to determine the evolution of the residual stenosis, an angiographic study was performed 5 ± 1 month and 37 ± 20 months after the procedure. Coronary angioplasty produced an initial reduction in the percentage of stenosis from 72 ± 13 % pre-PTCA to 41 ± 14 % (p< 0.0001) immediately post-PTCA. In the early angiogram 5 ± 1 month post-angioplasty, the residual stenosis showed a severity of 31 ± 14 % (p<0.001 vs immediately post-PTCA). Additionally, in the control performed 37 ± 20 months after, the residual stenosis experienced a further reduction to 23 ± 15 % (p<0.001 vs 5 months).
CONCLUSIONS: Restenosis post-angioplasty and progression of atherosclerosis are independent phenomena. In patients without restenosis, the residual stenosis post-angioplasty shows a long-term reduction during the follow-up.

Texto completoBackground. Nitroglycerin tberapy is associated with specific biochemical changes in the vasculature that may lead to an increased vascular sensitivity to vasoconstrictors. Catheter-based coronary interventions are associated with extensive arterial wall injury that appears to be associated with a cbronicatly abnormal endothelial function. Objectives: 1) To investiga te whether therapy with nitroglycerin would lead to abnormal coronary artery responses to the endothelium-dependent vasodilator acetylcholine. 2) To assess tbe endotelial-dependent vasomotor function in nonrestenotic coronary arteries more than 6 months following stent implantation, balloon angioplasty, and directional atherectomy. Metbods: Fifteen patients were randomized to continuous transdermal nitroglycerin, 0.6 mg/hour (n = 8), or no therapy (n = 7), for 5 days prior to a diagnostic catheterization. Patients had similar risk factors for endothelial dysfunction. Quantitative angiography was performed in the morning to measure the mean luminal diameter of the left anterior descending (LAD) in response to intracoronary acetylcholine (peak concentration, 10-4 molar). The transdermal preparation was removed from the nitroglycerin group and 3 hours 1ater experimental procedures were repeated. Thirty~nine patients, who were treated at least 6 months earlier with a coronary intervention for isolated prox.imal LAD stenosis, with no evidence of restenosis, were included in the study of the effects o f coronary interventions on endotelial vasomotor function. Twelve patients had been stented, 15 had been treated with balloon angioplasty, and 12 had undergone directional atherectomy. The change in diameter of the intervened LAD, and the unintervened circumflex coronary artery, in response to intracoronary ac~tylcholine were assessed by quantitative angiography. Results: In both studies the groups had similar angiographic characteristics and risk factors for endothelial dysfunctíon. In the nitroglycerin study, in the morning, th.e nítroglycerin group experíenced greater coronary constriction in response to acetylcholine infusion than those not receiving nitroglycerin (-19 .6 ± 4.2% versus -3.8 ± 3.0%~ P = 0.01). Three hours later, the nitroglycerin group continued to display greater constriction to acetylcholine (-24.1 ± 5.9%) as compared to the nonnitroglycerin group (-1.8 ± 4.8%; P < 0.01). When monúng and aftemoon responses to acetylcholine were compared, the increase in coronary constriction in the nitroglycerin group was greater than the change observed in the non-nítroglycerin group (P < 0.05). In the st11dy of the effects of coronary interventions on endotelial vasomotor function, the LAD constricted significantly more (P = 0.02) in previously stented patients (21.8 + 4.3%), as compared to patíents previously treated with balloon angioplasty (9.5 + 2.8%) or with directional atherectorny (9.1 + 3.6%). In contrast, acetylcholine infusion resulted in mild constriction in the circumtlex coronary artery which was similar in the three groups (P = 0.47). By multiple regression analysis, previous implant of a stent was the only significant predictor of LAD constriction (P = 0.008). Conclusions: Therapy with nitroglycerin causes abnormal coronary vasomotor responses to the endothelíum-dependent vasodilator acetylcholíne, which were persistent for up to 3 hours after nitroglycerin discontinuation. This nitrate associated vasomotor dysf'tmction has implications with respect to the development of nitrate tolerance and the potential for adverse events during nitrate withdrawal. More severe endothelial dysfunction was observed long term after stenting as compareci to balloon angioplasty or directional atherectomy. These findings may have implications with respect to the progression of atherosclerosis in coronary arteries subjected to pcicutaneous interventions.

Texto completoBakground: The presence of an increase in troponin I (cTnI) is common in patients who have undergone a percutaneous coronary intervention (PCI), but it is questionable if the myocardial lesion occurring in the intervention allows one to identify patients with a greater risk of presenting adverse cardiac events (ACE) .Objective : The overall objective of the study was to evaluate the immediate evolution of cardiac troponin I (cTnI) in patients undergoing elective coronary angioplasty with stenting, and also compare patients with serum changes after the procedure of coronary angioplasty stenting, with the clinical variables and the occurrence of adverse cardiac events (ACE) following 12 months.. Methods: This is a study of a prospective cut, which evaluates 49 consecutive patients who underwent coronary angioplasty with stent implantation. A cTnI serum dosage was done both before and after the procedure. Patients with a cut off >1.0 ng/mL before implantation were excluded. All the others received follow up for one year, to record the presence of ACE (death, acute myocardial infarction, another angioplasty). Results: cTnI serum elevations occurred in 21(45.7%) of the patients after the PCI. At the end of the follow up period, 11(23.9%) of the patients presented adverse cardiac events. There was no association between the cTnI serum elevation and the presence of ACE in the follow up. Conclusions: The elevation of cTnI found after a coronary angioplasty with stent implantation was frequent in our sample, but these elevations in serum did not show any association with clinical variables and the occurrence of adverse cardiac events following 12 months
A presença da elevação da troponina I(cTnI) é comum em pacientes submetidos a uma intervenção coronariana percutânea (ICP), porém é questionado se a lesão miocárdica ocorrida na intervenção permite identificar pacientes com maior risco de apresentar eventos cardíacos adversos. Objetivo: O objetivo geral do estudo foi avaliar o comportamento evolutivo imediato dos níveis séricos de troponina I (cTnI), em pacientes submetidos eletivamente à angioplastia coronária com implante de stent , e também, comparar pacientes com alterações séricas pós-procedimento de angioplastia coronária com implante de stent, com as variáveis clínicas e a ocorrência de eventos cardíacos adversos (ECA) no seguimento de 12 meses. Metodologia: Este é um estudo de coorte prospectivo, que avaliou 49 pacientes consecutivos, submetidos à angioplastia coronariana com implante de stent. Fez-se dosagens séricas de cTnI antes e após o procedimento. Pacientes com cut off > 1,0 ng/mL antes do implante foram excluídos, e os demais foram acompanhados em um ano de seguimento, para registro da presença de ECA (óbito, infarto do miocárdio e nova angioplastia). Resultados: Ocorreram elevações séricas de cTnI em 21(45,7%) dos pacientes após a ICP. Ao término do seguimento 11(23,9%) dos pacientes apresentaram eventos cardíacos adversos. A correlação entre a elevação sérica da cTnI e a presença de ECA no seguimento não mostrou associação. Conclusão: A elevação da cTnI encontrada após uma angioplastia coronariana com o implante de stent foi freqüente em nossa amostra, porém estas elevações séricas não apresentaram nenhuma associação com as variáveis clínicas e a ocorrência de eventos cardíacos adversos no seguimento de 12 meses

Texto completoObjective - To evaluate and compare the effectiveness of the ACC/AHA and Ambrose modified angiographic classifications in predicting clinical and angiographic outcomes. Methods - We studied 112 patients with unstable angina that had undergone coronary angioplasty and we applied the ACC/AHA and Ambrose modified angiographic classifications to the lesions that were considered to be culprit for the clinical findings in a historic cohort. Clinical and angiographic outcomes, wich were observed during hospitalization, were later identified. Results - According to the ACC/AHA and Ambrose modified classifications, the lesions were classified into complex ones in 58% and 46.4%, and into simple ones in 42% and 53.6%, respectively. Hospital discharge without complications was verified in 79.5% of the patients, “enzymatic” myocardial infarction in 14.5%, myocardial revascularization surgery in 2.4%, and death in 3.6%. The success rate achieved in angioplasty was of 73.2%, failure without complications of 20.5%, and acute occlusion of 6.3%. Both classifications were ineffective in predicting the clinical outcomes (modified ACC/AHA p=0.199; modified Ambrose p=0.867). In the prediction of the angiographic outcomes, a tendency to a significant difference between the simple and the complex lesions was observed when the ACC/AHA classification was applied (p=0.08) and a 6 significant though borderline difference, when it was applied the modified Ambrose classification (p=0.05). Conclusions – 1. Both angiographic classifications were ineffective in predicting clinical outcomes, though they presented a tendency to be effective in predicting angiographic in-hospital outcomes in patients with unstable angina that had undergone coronary angioplasty The Ambrose modified angiographic classification was not more effective than the ACC/AHA modified classification in predicting clinical and angiographic outcomes.

A doença arterial coronariana (DAC) é uma das principais causas de óbito e de perda de qualidade de vida ao longo do tempo. Seu tratamento pode ser clínico ou por meio de técnicas como a angioplastia percutânea ou a revascularização cirúrgica do miocárdio. Multidimensional, a DAC exerce fortes impactos físicos, emocionais e sociais. Por isso, além das avaliações clínicas, são indispensáveis as informações sobre a qualidade de vida e funcionalidade dos pacientes para uma análise mais precisa de suas condições após o tratamento. O objetivo deste estudo foi avaliar a percepção da qualidade de vida e a funcionalidade em pacientes com DAC nos momentos antes da revascularização cirúrgica ou da angioplastia, na alta hospitalar e 60 dias após a intervenção. Foram avaliados 90 pacientes divididos em grupos por procedimento. Utilizou-se uma ficha com perfil demográfico, questionário genérico de avaliação da qualidade de vida “The Medical Study 36-item Short-Form Health Survey” (SF-36) e escala de “Medida de Independência Funcional” (MIF). Observou-se, no perfil demográfico, a predominância do gênero masculino (58,9%), escolaridade com o ensino fundamental incompleto (64,4%) e índice de massa corporal (IMC) acima do ideal (37,8% sobrepeso e 25,6% obesidade). O grupo de angioplastia apresentou os melhores escores de qualidade de vida antes do procedimento nos domínios “aspectos físicos”, “dor”, “vitalidade”, “aspectos sociais” e na questão de avaliação da saúde anterior. Na alta isso se manteve com o acréscimo do domínio “capacidade funcional”. No momento 60 dias após o procedimento, a angioplastia obteve melhores escores em “aspectos físicos” e “aspectos sociais”. Na comparação entre os momentos, os domínios “capacidade funcional” e “dor” pioraram na alta para o grupo cirurgia, e melhoraram após 60 dias...

Texto completoA detecção da reestenose intrastent é importante na prática clínica fornecendo informações úteis para a orientação terapêutica. Os objetivos deste estudo foram, avaliar a eficácia do teste ergométrico (TE) na detecção de reestenose após angioplastia transluminal coronariana com implante de stent convencional (ATC-stent), comparando este método com os resultados obtidos com a cineangiocoronariografia. Foram estudados 25 pacientes assintomáticos, com idade entre 44 e 83 anos, que realizaram ATC-stent há, no mínimo, seis meses e no máximo um ano. Os pacientes foram submetidos ao TE empregando-se o protocolo de Bruce. O critério de positividade para isquemia foi o infra-desnivelamento do segmento ST > 1mm, aferido no ponto J e com morfologia horizontal ou descendente. Os resultados obtidos no TE foram comparados com aqueles da cineangiocoronariografia sendo considerada como reestenose intrastent a presença de lesões com obstrução >50%. Foram estimadas a sensibilidade e especificidade e o valor preditivo positivo e negativo do procedimento. Dos indivíduos estudados, 10 (40%) apresentaram reestenose intrastent pelo critério angiográfico e apenas 3 (12%) tiveram TE positivo para isquemia. A relação entre o TE e a cineangiocoronariografia não foi significativa (p=0,315), indicando que os testes são independentes. A concordância entre os diagnósticos foi baixa (coeficiente Kappa: 0,151), o mesmo ocorrendo com a sensibilidade (20%). A especificidade do TE foi elevada (93%), sendo o valor preditivo positivo 65,56% e o valor preditivo negativo 63,63%. A eficiência global do teste é baixa com acurácia estimada em 63,98%. Em conclusão, nas condições estudadas o TE tem baixa sensibilidade e alta especificidade na detecção de reestenose intrastent em pacientes assintomáticos. A eficiência global do TE é baixa.

Texto completoLong term outcomes for drug eluting stents are better than those for bare metal stents, especially for restenosis. However, drug eluting stents are usually implanted in more complex patients, theoretically lessening the difference in the outcomes. To compare the outcomes of paclitaxel stents (GI) in complex patients and bare metal stents (GII), in less complex patients. For some two years (mean: 17 months), 220 patients were analyzed prospectively: 111 in GI and 109 in GII. Their general survival and cardiovascular event-free survival rates were assessed through the Kaplan-Meier method. Using the criteria of the World Health Organization (WHO), the incremental cost-effectiveness ratio (ICER) was calculated for each restenosis avoided. Propensity scores was used to reduce selection bias by equating both groups based on these covariates. Men predominated in both groups (n=174 66.8%), with no differences between them, including age, ranging from 42 to 91 years (65.9 years). The main differences, with higher rates in GI, were diabetes: GI=60 (50.4%) and GII=19 (17.4%), p=0.0001; family history: GI=43 (38.7%) and GII=24 (22.1%), p=0.007; previous acute myocardial infarction: GI=54 (48.6%) and GII=31 (28.4%), p=0.002; previous coronary artery bypass graft: GI=24 (21.7%) and GII=6 (5.5%), p=0.0005; previous angioplasty: GI=28 (25.2%) and GII=17 (15.5%), p=0.077; acute coronary syndrome: GI=48 (43.3%) and GII=35 (32.0%), p=0.088. Multivessel patients were more frequent in GI=21 (18.9%) than in GII=11 (10.1%), p=0.029. However, the GII patients presented normal left ventricle functions more frequently: GI=51 (45.9%) and GII=85 (77.9%), p=0.0001. There were no differences between the groups for the number of lesions treated and number of arteries per patient. The bare metal stent group presented simpler lesions: Type A GI=43 (25.6%); GII=65 (45.5%), p=0.0002; Type B: B1 GI=50 (29.7%) and GII=35 (24.5%), p=0.30; and B2 GI=51 (30.4%) GII=26 (18.1%), p=0.53; and Type C: GI=24 (14.3%) and GII=17 (11.9%), p=0.53. The restenosis per patient was lower in GI=7 (6.3%) than in GII=14 (12.8%), but without statistical significance (p=0.099). However, restenosis by lesion was lower in GI=7 (4.1%) than in GII=14 (9.8%) p=0.0489. The general two-year survival rate was 96.2% in GI and 89.3% in GII (p=0.76) with similar event-free survival rates: major events (p=0.35) and restenosis (p=0.82). The propensity score showed that it was better to receive SF in patients: age >72, diabetics and lesions with diameter <3,2mm and length >18mm. Assessing all the clinical, angiographic and technical factors through the logistic regression curve, the only the major predictor was stent size. With the value corrected, GII has 4.3 times more chances of restenosis than GI. In terms of costs, the decision tree was modeled on the restenosis in the two groups: GI=6.3% versus GII=12.8% in 17 months (mean). The net benefit of implanting of paclitaxel stents was a 6.3% reduction in restenosis, with a cost increase of R$ 9,590.00. The incremental cost-effectiveness ratio (ICER) was R$ 147,538.00 for avoided restenosis, whose incremental value exceeds the threshold suggested by the WHO (World Health Organization). The results were similar in GI and GII, despite more diabetes and other co-morbidities in GI. Restenosis by lesion was higher in GII. The size of the stent was the only important variable for restenosis. The use of drug eluting stents in patients is not a cost-effective strategy in actual practice.

Texto completoThe present study evaluated the myocardial distribution of 99mTc-sestamibi using models of coronary angioplasty in humans and of celular fractionation in isolated perfused rat hearts. To address the apparent discrepancy between cultured cells and whole heart preparations, Langendorff-perfused rat healts loaded with hexakis (2-methoxyisobutyl isonitrile) technetium (I) (99mTc...MIBI) were fractionated by a standard differential centrifugation lnethod and fractional contents of 99mTcMIBI were correlated with the mitochondrial marker, malate dehydrogenase (MDH), and mitochondrial substrates. The "cytosolic" fraction nominally contained 88% (84-96) of total 99mTc-MIBI,but also contained 91%(89-94) of total MDH activity by this method. Chromatographic analysis of activity in the "cytosº lic" fraction demonstrated that > 95%of the agent was present as the original free cationic complex; binding to a small molecular weight cytosolic protein was not involved in localization. Addition of the mitochondrial uncoupler CCCP (5 JlM) to both "mitochondrial" and "cell fragment" peUets released up to 84% of 99mTc-MIBI content and addition of the mitochondrial substrate succinate (lQJM) in the presence of rotenone (lIJM) enhanced 99mTc-MIBI content by up to 139% over the controI. These correlative data from rat hearts indicate that approximately 90% of 99mTc-MIBI activity in vivo is associated with mitochondria in an energy-dependent manner as a free cationic complex, but migrates during fractionation/ centrifugation. To assess the early benefits of successful percutaneous translunlinal coronary angioplasty (PTCA), 99mTc-MIBI Single Photon Emission Comrn ted Tomography (SPECT) was used in nine consecutive patients. SPECT stress studies were done by artificial cardiac pacing just prior to PTCA and 16-20 hours later, with perfusion imagens obtained 2-3 hours after pacing stress and 99mTcMIBI injection. Angiographic restenosis was delnonstrated in three patients at a later date, and alI of these showed no significant improvement on the perfusion study after PTCA. AlI four patients asymptomatic at 7 months following PTCA had an avarege 15% ·improvement in segmentaI perfusion .afier the procedure. In two patiens symptomatic afier PTCA, one showed angiographic patency and had > 15%improvement in perfusion, while the second showed no scintigraphic lmprovement (no angiographic data obtained). These preliminary observations suggest that 99mTc-sestamibi is an iUlportant adjunct to angiography in estimating the amount of myocardium "at risk" before and after PTCA.

As pessoas, que vivem mais, estão expostas a determinadas doenças crônicas não transmissíveis. Dentre essas, a Doença Arterial Coronariana. Tornando-se primordial, portanto, que os cuidados de enfermagem dispensados aos idosos submetidos à Angioplastia Coronariana Transluminal Percutânea (ACTP) estejam voltados para além do atendimento hospitalar. Objetivo: Elaborar e Validar uma Tecnologia Educacional em forma de manual visando o autocuidado do idoso submetido à ACTP. Metodologia: Pesquisa do tipo metodológica, sustentada nas teorias de Dorotéia Orem. Critérios de inclusão: pessoas a partir de 60 anos submetidas à ACTP. Critérios de exclusão: Idosos com distúrbios cognitivos ou psiquiátricos. A pesquisa desenvolveu-se na hemodinâmica do Hospital Universitário Antonio Pedro e no Programa de Enfermagem na Atenção a Saúde do Idoso e seu Cuidadores - UFF. Em atendimento à resolução 66 de 12 de dezembro de 201260, foi submetida ao Comitê de Ética em Pesquisa, aprovado pelo parecer de Nº 234.557, de 08 de março de 2013. 1º Etapa da pesquisa- realizou-se entrevista utilizando um questionário semiestruturado, para identificar e descrever as necessidades dos idosos submetidos à ACTP relacionado ao autocuidado. As entrevistas foram realizadas no período de maio a julho de 2013, com vinte idosos (20). A análise desta etapa subsidiou a elaboração da tecnologia educacional. 2º Etapa da pesquisa - Elaboração da Tecnologia Educacional - 3ª Validação da Tecnologia Educacional - foram utilizados dois instrumentos de validação da escala Likert. Um instrumento respondido por doze juízes especialistas e o outro instrumento pelo público alvo, nove idosos, da primeira etapa da pesquisa, os que concordaram participar da pesquisa, assinaram o termo de consentimento livre esclarecido e lhes foi entregue um kit contendo a tecnologia educacional e o instrumento para avaliação. Análise da 1ª Etapa da pesquisa - interpretação, transcrição dos dados e análise temática de conteúdo. Resultados: emergiram sete categorias relacionadas ao saber do idoso sobre a ACTP, apontando para déficit de autocuidado relacionado ao conhecimento acerca do procedimento. As categorias temáticas serviram de subsídio para a elaboração da Tecnologia educacional. Análise da 2ª Etapa da pesquisa - análise estatística dos questionários da Escala Likert: baseou-se na frequência simples do número de vezes em que os especialistas e os idosos optaram pelas diferentes valorações em cada bloco do instrumento, a saber: Totalmente Adequado (TA); Adequado (A); Parcialmente Adequado (PA) e para Inadequado (I). Resultados: A TE foi considerada validada os itens que obtiveram concordância maior ou igual a 70%, o manual foi considerado adequado quanto aos itens propostos para avaliação. Os itens que não alcançaram o índice de concordância de 70% foram corrigidos e modificados. 3ª Etapa: Adequação da Tecnologia Educacional - de posse de todas as avaliações realizadas, o manual recebeu o tratamento e os ajustes necessários. Conclusão: foi construído um manual educativo impresso, um vídeo com o mesmo conteúdo e um folder explicativo, tais produtos estão sendo compartilhados com as pessoas idosas que necessitam ser instrumentalizadas de maneira mais eficaz nos serviços de alta complexidade para executar o autocuidado. Este estudo servirá de modelo para outros cenários devido o seu caráter inovador de cuidar educando da pessoa idosa no setor de alta complexidade
People who live longer are exposed to certain chronic diseases. Among these, the Coronary Artery Disease. It becomes paramount, therefore, that nursing care dispensed to elderly undergoing Percutaneous Transluminal Coronary Angioplasty (PTCA) are facing beyond hospital care. Objective: To Develop and Validate an Educational Technology as a manual the self-care of the elderly undergoing PTCA. Methodology: Methodology type research, supported in the theories of Dorotéia Orem. Inclusion criteria: people aged over 60 years old undergoing PTCA. Exclusion criteria: Older adults with cognitive or psychiatric disorders. The research was developed on the hemodynamics of Antonio Pedro University Hospital and Nursing Program in Health Care of the Elderly and their Caregivers - UFF. In compliance with Resolution 66 of December 12, 201260, it was submitted to the Committee for Research Ethics approved by Opinion No. 234 557 of March 08, 2013. 1st Step of the research – it was carried out using a semi-structured interview questionnaire to identify and describe the needs of the elderly undergoing PTCA related to self-care. The interviews were conducted in the period of May to July 2013, with twenty (20) older adults. The analysis of this step subsidized the development of educational technology. 2nd Step of the research - Development of Educational Technology - 3rd Educational Technology Validation - validation of two instruments of Likert scale were used. An instrument responded by twelve expert judges and other instrument by the target audience, nine elderly, from the first stage of the research who agreed to participate in the study, they signed a consent form and was handed a kit containing educational technology and the instrument for review. Analysis of the 1st Step of the research - interpretation, data transcription and thematic content analysis. Results: Seven categories emerged related to knowing about the elderly PTCA, pointing to self-care deficit related to knowledge about the procedure. The themes categories were used as input for the development of educational technology. Analysis of the 2nd Stage of the research - statistical analysis of the questionnaires of Likert Scale: based on the simple frequency of the number of times that the experts and the elderly opted for different valuations on each block of the instrument, namely: Totally Adequate (TA) ; Adequate (A); Partially Adequate (PA) and Inadequate (I). Results: The TE was considered validated items that had greater than or equal to 70% agreement, the manual was considered adequate to the proposed items evaluation. Items that have not reached the level of agreement of 70% were corrected and modified. 3rd Step: Adequacy of Educational Technology - in possession of all the assessments, the manual received the necessary adjustments. Conclusion: it was built a printed teaching manual, a video with the same content and an explanatory brochure. Such products are being shared with the elderly that need to be manipulated more effectively in highly complex services to perform self-care. This study will be a model for other scenarios due to its innovative character of caring for the elderly in educating highly complex sector

Texto completoThe advances in health have led to reduced mo rbidity and improved survival of patients living with coronary diseases. However, Acute Cor onary Syndrome (ACS) represents one of the most relevant public health issues nowadays. The aim of this study was to assess the clinical evolution of patients who suffered from ACS, fr om their first admission to the hospital until two years after that episode. The main interest variables investigated were: mortality, hospital readmissions and myocardial reva scularization therapies (percuta neous coronary intervention - PCI and Coronary Artery Bypass Grafting surg ery - CABG). This research was designed as an observational cohort study. The study sample was patients admitted into a general school hospital due to the first episode of ACS, from May 2006 through July 2009. Data were collected in 2011 from patients\' medical records and the hospital\'s appointment schedule database, using a form designed by the researcher. Data were analyzed by chi-square, Fisher\'s exact test and t-Student association tests for independent samples. The significance level was 0.05. Mortality rate was calculated by dividing the number of deaths occurred up to two years after the first ACS episode by the total period of observation taken within the study. As such, 234 patients took part in the study, 140 (59.8%) were diagnosed with Acute Myocardial Infarction (AMI) and 94 with Unstable Angi na (UA). The mean age was 58 years old (s.d.=12.2), most were male (69.2%). During hosp ital stay there was no association between medical complications and clinical manifest ation of ACS. Patients with UA had mean hospital stay higher than AMI patients (12.5 and 10 days, respectively), alt hough this was not statistically relevant. PCI were more prevalen t in AMI patients, whereas CABG were to UA patients, displaying statistically relevant association between these variables. During the two-year follow up period after hospital discharge, 71.4% of patients were submitted to, at least, a myocardial revascularization pr ocedure. 27.4% of patients were hospitalized again, 71% of this group had to be readmitted and 6.5% had been readmitted five times. At their first readmission, the most prevalent cause was a sc heduled PCI and the following hospitalizations were due to angina. The hospital mortality rate was 3%, as 13 deaths occurred during the period of study, with no statistically significance between the ACS manifestations. The general mortality rate of this study was 35.75/1000 people per year. The results of this study improved our knowledge over the profile of this population admitted into a general tertiary hospital due to their first ACS episode. It also shone some light over the clinical evolution of this disease during hospitalizat ion and at long term period.

Texto completoBackground Accurate characterization of atherosclerotic plaque interaction during stent deployment is crucial to understand vascular compliance and healing. We sought to determine whether plaque composition assessed by optical coherence tomography (OCT), influences acute changes at index procedure and vascular healing at follow up. Methods Patients treated with a single drug-eluting stent type (cobalt chromium with bioabsorbable polymer eluting sirolimus stent) were prospectively included, following a pre-defined step-by-step progressive vessel dilatation. Sequential OCT imaging were performed at the index procedure (baseline and at each time point of the protocol) and at follow up, co-registered and analyzed every 0.6mm for quantitative measurements. Semi-quantitative plaque assessment was performed at baseline by dividing cross-sections into 4 quadrants, with each quadrant labeled according to its most prevalent component (fibrotic, calcific, lipid). OCT assessments of stent-vessel interactions were used as a surrogate for vessel injury and healing after stent implantation. Results A total of 22 lesions (1stent/lesion) of 20 patients and 2298 OCT crosssections were analyzed at the index procedure. For an average of 19.7 months (591.88 ± 60.52 days), 17 of the patients and 19 lesions (86%) underwent OCT imaging at follow up. The predominant percentage plaque component was fibrotic (fibrotic = 46.84 ± 16%; lipid = 17.63 ± 10.72%; calcific = 4.63 ± 5.9%; normal = 29.16 ± 12.24; non-analyzable = 1.74 ± 5.35%). There was an increase in lumen (10atm = 5.5 (4.5 - 7.4) mm2, 14-16atm = 6.0 (4.7 - 7.70) mm2, 20atm = 6.7 (5.5 - 8.2) mm2; P < 0.001) and stent (10atm = 5.2 (4.3 - 7.0) mm2, 14-16atm = 5.7 (4.5 - 7.5) mm2, 20atm = 6.5 (5.3 - 7.9) mm2; P < 0.001) areas, with an increase in tissue prolapse area (10atm =0.09 (0.06 - 0.12) mm2, 14-16atm =0.10 (0.06 - 0.15) mm2, 20atm =0.15 (0.08 - 0.20) mm2; P < 0.01). Segments with high fibrocalcific content tended to have decreased minimal luminal areas along the intervention time-points. Conversely, plaques with high lipid content had increased minimal luminal areas during sequential dilatations. Moreover, plaques with high fibrocalcific tissue at baseline had significantly smaller neointimal growth at follow-up, whereas the degree of lipid content or normal tri-layered vessel had no impact on neointimal formation. OCT surrogates of vessel injury after coronary stenting significantly correlated with neointimal growth at follow-up. Conclusions: Tissue composition of underlying plaques significantly influences the acute mechanical and the long-term behavior of coronary vessels undergoing stent implantation. In addition, vessel injury after coronary stenting is potentially linked to future neointimal growth at follow-up

Texto completoBackground: Although clinical benefits of coronary interventions have been confirmed, their effects on quality of life (QOL) are still less studied. This study is justified by the scarcity of studies that have evaluated the QOL of patients with CAD undergoing one of three types of treatment available along 10 years of follow-up. Objective: To evaluate and compare the QOL in patients with multivessel coronary disease randomized to undergo coronary artery bypass surgery, angioplasty or medical treatment, and followed during 10 years. Methods: A prospective study whose data were obtained from the database of the protocol MASS II (\"The Medicine, Angioplasty or Surgery Study\") consisting of 611 patients randomized to one of three available treatments for Coronary Artery Disease. For this study, we analyzed 334 participants who completed the questionnaire of QOL since the beginning of the study and annually, until they reach 10 years of follow-up. The QOL was assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). We performed descriptive statistics, chi-square test for categorical variables and the independent sample t test. Mean quality of life for the time variable groups were evaluated by analysis of variance (ANOVA) with repeated measures and multiple comparisons. Results: 148 patients (47.3%) had AMI, 97 (25.9%) underwent CABG or PCI, 16 (4.8%) suffered stroke and 293 (87%) reported angina along the 10 years of follow up. At baseline, patients in the CABG group had the worst condition in the physical component compared to PCI or MT. All three treatments strategies have achieved a significant improvement in all dimensions of QoL (P < 0.001). Medical Treatment: In this group, there was improvement in the mental component in 83.7% of patients, while 16.3% had worsening of this condition. Regarding the physical component, 84.7% and 15.3% had their condition improved and worsened, respectively. Surgery: For the mental component, 85.4% and 14.6% achieved improvement and worsening in their condition, respectively. Regarding the physical component, 92.7% and 7.3% had their condition improved and worsened, respectively. Angioplasty: In this group, the mental component improved by 77.8%, while 22.2% had worsening of this condition. Regarding the physical component, 73.0% and 27.0% had their condition improved and worsened, respectively. Comparing the treatment groups with respect to physical component at baseline, there was significant difference among the treatment groups (P < 0.001). However, no significant difference was found at 5 and 10 years of follow up among them. On the other hand, in respect to mental component, no statistically significant difference was found among the treatment groups in all time point of the study. Conclusion: Improving the perception of QoL was observed in all dimensions and in all three forms of treatment after five years and has persisted up 10 years of follow up. Intervention strategies have not achieved better results in quality of life than TM alone

Texto completoBACKGROUND: Historically, myocardial revascularization procedures, either by coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI), are assumed as effective therapeutic options for the protection of the ischemic myocardium. However, it is not established if those procedures are responsible for left ventricular function preservation, or even if their absence may contribute for the deterioration of left ventricular ejection fraction (LVEF). OBJECTIVES: to evaluate the evolution of LVEF in patients with chronic multivessel coronary heart disease and left ventricular function initially preserved, submitted to CABG, PCI or medical treatment (MT), after ten years of follow-up (MASS II substudy). METHODS: Transthoracic echocardiography was performed in patients with multivessel coronary heart disease, participants of MASS II trial, previously to randomization for one of the three possible therapeutic strategies (CABG, PCI and MT), and after 10 years of follow-up. LVEF was measured by the biplane method (Simpson) or alternatively by the Teichholz method. RESULTS: Of the 611 patients participants of MASS II trial, 422 were alive after a follow-up of 10.32 (±1.43) years. 350 had LVEF reassessed: 108 patients in MT group, 111 in CABG group and 131 in PCI group. Main baseline characteristics were similar among the three groups, including demographic, angiographic and laboratorial findings. The occurrence of acute myocardial infarction (AMI) was also similar among the 3 groups. There was no difference of LVEF either at the beginning (0.61 + 0.07, 0.61 + 0.08 e 0.61 + 0.09 respectively for PCI, CABG and MT, p=0.675) and the end of follow up (0.56 + 0.11, 0.55 + 0.11 e 0.55 + 0.12 respectively for PCI, CABG and MT groups, p=0.675). However, there was a slight, but significant reduction (P<0.001) of LVEF, similar on the three therapeutic groups (p=0.641). The impact of other variables over LVEF evolution, such as gender, age, diabetes, arterial pattern (including, left anterior descending coronary artery commitment) and additional revascularization, were also analyzed, with no influence on the evolution of LVEF. However, the presence of previous AMI (OR 2.50, 95% CI 1.40-4.45; p= 0.0007) and the occurrence of AMI during follow up (OR 2.73, 95% IC 1.25- 5.92; p=0.005) were associated with an increased risk of developing LVEF < 45%. Also, AMI during follow-up was responsible for a greater reduction of LVEF (reduction delta of 18.29 ± 21.22% and 6.63 ± 18.91%, respectively for patients with and without AMI during follow-up, p=0.001). CONCLUSION: Compared with PCI or CABG, the Medical group, with unprotected coronary disease by mechanical revascularization, showed no differences in left ventricular function after 10 years of follow-up. Moreover, regardless of therapeutic strategy applied, ventricular function remained preserved without AMI

Texto completoLas Enfermedades cardiovasculares (ECV) son principal causa de fallecimientos en el mundo, la Cardiopatía Coronaria Isquémica (CCI) es la más frecuente, tiene alta morbi-mortalidad. El riesgo de desarrollarla en varones es de 40 a 49% y en mujeres de 32%, según el estudio de Framinghan. La angina estable es la manifestación inicial de la enfermedad arterial coronaria crónica en aproximadamente la mitad de los pacientes. Se han diseñado Técnicas de revascularización miocárdica: Angioplastia Percutánea con Stent (ICP) y Revascularización Quirúrgica con Puentes arteriales y venosos (CABG) los que han experimentado importantes avances tecnológicos, se cuestiona su papel en el tratamiento de los pacientes con enfermedad coronaria crónica estable. Objetivos: Se compararon las tasa de Mortalidad y de eventos adversos mayores así como la función sistólica (Fracción de Eyección) del ventrículo izquierdo entre dos grupos de pacientes CABG vs ICP a los 36 meses de realizado el procedimiento Métodos: Estudio de Tipo Investigación documental, de diseño Analítico, observacional, retrospectivo y Transversal. Luego de aplicar criterios de inclusión, exclusión entre pacientes con enfermedad coronaria crónica estable sometidos a revascularización miocárdica por angioplastia percutánea con stent (ICP) o revascularización quirúrgica de miocardio (CABG) en el Centro Médico Naval entre el periodo 2006 – 2008, a los 36 meses de realizado el procedimiento. Análisis estadístico (Programa informático SPSS), Chi cuadrado, se utilizó para comparación de proporciones y el Test de Student para las variables continuas. Se aceptaron como significación estadística todos los valores p<0,05. Resultados: En el periodo de estudio se evaluaron 94 pacientes con enfermedad coronaria crónica isquémica estable (CCI), 45 sometidos a revascularización quirúrgica (CABG) y 49 a revascularización vía percutánea (ICP). La edad media fue 68 años, predominando el sexo masculino (88.29%), con antecedentes de Hipertensión Arterial (76.60%), Dislipidemia (67.02%), Diabetes Mellitus (38.29%). El Infarto de miocardio antiguo así como la revascularización miocárdica previa en el grupo de Intervencionismo percutáneo fue más frecuente. En la evaluación del riesgo pre-procedimiento medido por el Euroscore en ambos grupos, el riesgo alto fue 2.5 veces más en el grupo de intervencionismo (p<0,05). En el grupo quirúrgico (CABG) se encontró el compromiso de Arteria Descendente anterior (91.11%) y Tronco Principal de Arteria Coronaria Izquierda (24.44%). Para la revascularización se utilizó puentes venosos (95.5%) y Arteria Mamaria Interna (84.44%) con un promedio de 3 vasos tratados. En el caso del intervencionismo percutáneo (ICP) los Stent liberadores de fármacos (DES) se utilizaron en 95.92%, siendo la Arteria Coronaria Derecha la más intervenida (44.90%), seguida de la Circunfleja (40.82%) y la Descendente Anterior (36.37%). En un gran porcentaje (95.92%) se logro la re-perfusión con flujo TIMI III. En el grupo de intervencionismo (ICP) como evento adverso mayor se encontró Infarto de miocardio, accidente cerebro vascular y re-intervención percutánea sin una significancia estadística. La Función Sistólica del Ventrículo Izquierdo medida por ecocardiografía con la Fracción de Eyección (FE) al final del periodo de estudio fue muy similar en ambos grupos y en más de la mitad de casos con una FE > 55%. La tasa de mortalidad en el grupo de CABG fue 2.22% y para el ICP de 6.12%. Conclusiones: La tasa de mortalidad en el grupo de CABG fue 2.22% y para el ICP de 6.12%. Los eventos adversos mayores evaluados como infarto, accidente cerebrovascular y el intervencionismo percutáneo fueron más frecuentes entre los pacientes sometidos a Revascularización Percutánea, pero sin significancia estadística. A los treinta y seis meses de haber sido intervenidos la Fracción de Eyección del Ventrículo Izquierdo fue muy semejante en los pacientes de ambos grupos.

Texto completoThis thesis aims to test the hypothesis that atrial ischemia is itself a promoting factor to develop atrial arrhythmias. To answer this question, the study takes as research model the performance of coronary angioplasty, a common clinical scenario. The thesis consists of two distinct parts: In the first, the different anatomical patterns of atrial coronary circulation are reviewed and the scientific interest of the hypothesis is justified. Subsequently, the results of a retrospective cohort study are shown. This analysis determines, for the first time, the incidence and predictors of atrial branch occlusion during elective percutaneous coronary intervention. In the second part, the results of a prospective cohort describe the clinical, biochemical and electrophysiological consequences of this complication. Thus, the incidence of myocardial infarction due to occlusion of atrial branch occlusion is determined and the risk of acute atrial arrhythmias during the early phase of this entity is clarified. Finally, the major findings of the thesis are compared with those found by other authors in previous literature and the scopes of the clinical implications are discussed.

Texto completoIntroduction: Primary percutaneous coronary intervention reduces mortality in patients with ST elevated myocardial infarction (STE MI). The objective was to evaluate the 30 days in-hospital mortality according to door-to-balloon time and total ischemic time in patients treated with primary PCI. Methods: A retrospective cohort study was performed including patients with STE MI who underwent primary PCI at a national reference hospital in Lima, Peru. A Cox Regression analysis was performed for door-to-balloon time less than 90 minutes and total ischemic time less than 12 hours as predictors and in-hospital mortality as outcome. Results: During 2010’2014, 296 STE MI patients underewent PCI. From them, 82,4% were male. The mean age was 66,5 ±11,8 years. The 30-day mortality was 8,11%. The proportion of patients with total ischemic time less than 12 hours and door-to-balloon time was 82,43% and 33,11% respectively. No association between these intervals and 30-day mortality was found. Cardiac arrest (HR: 2,9 95%CI 1,09-7,72), cardiogenic shock at the admission (HR: 7,06; 95%CI: 2,84- 17,59) and TIMI flow less than 3 after primary PCI (HR: 4,21; 95%CI: 1,73-10,19) were associated with higher 30-day mortality.. Conclusion: No association between mortality and lower total ischemia time or door to ballon time mortality was found. A significant delay was observed in hospital arrival and performing revascularization.

Texto completoBackground: The release of myocardial necrosis biomarkers after percutaneous coronary intervention (PCI) frequently occurs. However, the correlation between biomarker release and the diagnosis of procedurerelated myocardial infarction (MI) (type 4a) has been controversial. This study aims to evaluate the amount and pattern of cardiac biomarker release after elective PCI in patients without the image of a new MI after the procedure assessed by cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE). Methods: Patients with normal baseline cardiac biomarkers referred for elective PCI were prospectively included. CMR with LGE was performed in all of the patients before and after the interventions. Measurements of troponin I (TnI) and creatinekinase MB fraction (CK-MB) were systematically performed before and after the procedure. Patients with a new LGE on the post-procedure CMR were excluded. Results: Of the 56 patients without the evidence of a procedure-related MI assessed by the CMR after PCI, 48 (85.1%) exhibited a TnI elevation peak above the 99th percentile. In 32 (57.1%), the peak was greater than 5 times this limit. On the other hand, 17 (30.4%) had a CK-MB peak above the limit of the 99th percentile, and this peak was greater than 5 times the 99th percentile in only 2 patients (3.6%). The median peak release of TnI was 0.290 (0.061 to 1.09) ng/ml, which is 7.25-fold higher than the 99th percentile. Conclusions: In contrast to CK-MB, TnI release often occurs after an elective PCI procedure, despite the absence of a new LGE on CMR

Texto completoBackground. The costs for treating coronary artery disease (CAD) are high worldwide. We performed a post hoc analysis of cost-effectiveness of 3 therapeutic strategies for multivessel CAD. Methods. From May 1995 to May 2000, a total of 611 patients were randomly assigned to CABG (n=203), PCI (n=205), or MT (n=203). This cost analysis study was based on the perspective of the Public Health Care System. Initial procedural and follow-up costs for medications, cardiology examinations, and hospitalizations for complications were calculated after randomization. Life-years and quality-adjusted life years (QALY) were used as effectiveness measures. Incremental cost-effectiveness ratios (ICER) were obtained by using nonparametric bootstrapping methods with 5000 resamples. Results. Initial procedural costs were lower for MT. However, the subsequent 5-year cumulative costs were lower for CABG. Compared with baseline, the 3 treatment options produced significant improvements in QALY. After 5 years, PCI and CABG had better QALY results compared with MT. The ICER results favored CRM and PCI when compared to the TM, since the PCI in relation to the CRM was more costeffective in 61% for the thresholds up to 3 GDP per capita per QALY. On the other hand, sensitivity analysis showed MT as the preferred therapy compared with CABG and PCI, in the analysis considering higher costs. Conclusion. At 5-year follow-up, the 3 treatment options yielded improvements in quality of life, with comparable and acceptable costs. However, despite higher initial costs, the comparison of costeffectiveness after 5 years of follow-up among the 3 treatments showed both interventions (CABG and PCI) to be cost-effective strategies compared with MT

Texto completoOptical Coherence Tomography (OCT) imaging is promising in decision making during Percutaneus Coronary Interventions {PCI) procedures, including evaluating controversial plaque lesions, assessing stent implantation, and surveying stent-related vascular injury. Thus, OCT has potential to guide interventional cardiologists throughout the stent implantation procedure, impacting on planned interventional strategy. In addition, OCT is the most novel image technology to predict stent edge dissection for patients with non-ST-segment elevation ACS, enabling risk stratification of patients who are at a higher risk of this complication. Large-scale randomized trials are now warranted to assess whether OCT results and guidance during de procedure improve long-term clinical outcomes of PCis

Texto completoAIMS: Evaluate the SYNTAX score (SS) in predicting major adverse cardiovascular events (MACCE) in coronary angioplasty (PCI) and surgery (CABG) groups in diabetic patients with symptomatic multivessel Coronary Artery Disease (CAD). Comparing CABG and PCI according SS category. METHODS AND RESULTS: Single center study including 188 patients randomized to PCI (n=96) or CABG (n=92), followed for a median of 6.5 (0.1 to 8.6) years. There were no differences in MACCE in the CABG group regardless of the SS categories (13.5% low, 15.6% intermediate, 34.8% higher, p=0.10), while in the PCI group significant differences in MACCE were detected (17.6% low, 52.5% intermediate and 40.9% higher, p=0.02). In the PCI and CABG groups SS did not predict MACCE in the Cox regression analysis (p > 0,05). Comparing PCI and CABG according SS category there was a higher incidence of MACCE in patients with intermediate SS in the PCI group (52.5% in PCI group vs 15.6% in CABG group, p=0.002) and no difference were observed in patients with low (17.6% in PCI vs 13.5% in CABG, p=0.59) and high SS ( 40.9% in PCI vs 34.8% in CABG, p=0.68). CONCLUSIONS: In diabetic patients with multivessel CAD the SS was not an independent risk factor for MACCE in the PCI and CABG groups. Diabetic patients with intermediate SS showed higher MACCE in the PCI group versus CABG

Texto completoArterial access is a major site of complications after invasive coronary procedures. Among strategies to decrease vascular complications, the radial approach is an established one. Vascular closure devices provide more comfort to patients decreasing hemostasis and need for bed rest. However, the inconsistency of data proving their safety limits their routine adoption as a strategy to prevent vascular complications, requiring evidence through adequately designed randomized trials. The aim of this study is to compare the radial versus femoral approach using Angio-Seal for the incidence of arterial puncture site complications among non-ST-segment elevation acute coronary syndrome patients submitted to an early invasive strategy. This study is a unicentric, non-inferiority clinical trial where two hundred and forty patients with non-ST-segment elevation acute coronary syndrome were randomized to either radial or femoral access using Angio-Seal. The primary outcome was the occurrence of complications at the arterial puncture site until 30 days after the procedure, including major bleeding, hematoma >= 5 cm, retroperitoneal hematoma, compartment syndrome, pseudoaneurysm, arteriovenous fistula, infection, limb ischemia, arterial occlusion, adjacent nerve injury or the need for vascular surgery repair. With respect to demographic and clinical characteristics, there were differences only in terms of gender, with greater presence of female patients in the radial group (33.3% versus 20.0%, p = 0.020). There were no differences between the groups regarding the diagnosis of admission, ischemic changes present in the electrocardiogram, elevation of myocardial necrosis markers or risk scores, as well as the adjunct antithrombotic pharmacotherapy and features of the percutaneous coronary intervention. Hemostasis was achieved in the entire radial group with the use of selective radial compressor TR Band and in 95% of the procedures performed by femoral technique with Angio-Seal (p = 0.029). Except for a higher incidence of arterial occlusion in the radial group compared to the femoral, there were no differences among the other outcomes analyzed. According to the non-inferiority test for arterial access site complications in 30 days, it was found that the use of Angio-Seal not produced results inferior to the radial approach, considering the margin of 15% (12.5% vs. 13.3%, difference -0.83%, 95% CI -9.31 - 7.65, p for noninferiority <0.001). The main results of this study demonstrated that in a population of patients diagnosed with non-ST segment elevation acute coronary syndrome, who underwent invasive risk stratification, the use of the Angio-Seal vascular closure device confers to the femoral approach noninferiority in the incidence of arterial puncture site complications at 30 days when compared to the radial approach.

Am J Cardiol 2014;113(3):452-456. We made a prospective observational registry of consecutive patients treated with angioplasty in the context of STEMI and / or cardiogenic shock between 2007 and 2013. In the first phase of the registry (2007-2010) the analysis of different time intervals between symptom onset and reperfusion permited to identify weaknesses in the system and unjustified delays. The place where the first contact medical was made (hospital with or without 7/24 PCI or outpatient care by SEM) had an influence on the delay. The performance of the operation at work or on call time did not affect the delay, contrary to what had suggested other publications. With the launch of the Codi Infart in 2010, the improvement in the organization of the network was related to an increase in the number of patients who received reperfusion therapy and an increase in primary angioplasty as the treatment of choice with a reduction of the delay to reperfusion when compared with the previous period. The analysis of patients with cardiogenic shock showed that radial access was feasible in 2/3 of patients and that the absence of radial pulse was the main femoral approach. We find a relationship between radial access and decreased mortality in the multivariate analysis. In patients aged ≥75 years who underwent primary angioplasty radial access was possible in almost all cases (> 95%). Despite the complexity of patient monitoring showed an incidence of mortality and major cardiac events was significantly lower than that previously reported in this subgroup of patients when the procedure is performed by transfemoral access.

Texto completoIntroduction: The cost-effectiveness analysis in multivessel coronary artery disease treatment have gained importance in clinical trials, since the main treatment options: coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) and medical treatment (MT) have similar efficacy in certain subgroups of patient. Currently, the concernment in economic analysis have grown, since Medical Treatment costs have increased with the constant development of new technologies, but the available budget are finite and should be administered. Objective: prospectively analyze the comparative cost of the three medical treatments for stable multivessel coronary artery disease, during ten years follow-up. Methods: It was calculated the overall therapeutic cost of 611 patients in the clinical trial \"The Second Medicine, Angioplasty, or Surgery Study (MASS II) \", considering the remuneration provided by the health insurance system of the Heart Institute of HC/FMUSP converted to dollar currency. Afterward, the costeffectiveness analysis was conducted by adjusting the cumulative cost obtained at each group for the \"time free of clinical events\" and also for the combination of \"time free of events\" and \"time free of angina\". Results: The MT had a cumulative cost, at the end of ten years, of US$ 6,183.00; PCI had a cost of US$ 14,292.00; and the CABG group had a cumulative cost of US$ 12,316.00. The costs adjusted for \"events-free survival\" were US$ 11,136.00 for MT; US$ 26,912.00 for PCI and US$ 17,883.00 for CABG. There was a statistically significant difference between the 3 groups (p < 0.0001) and paired analysis showed lower cost for the medical treatment group compared with CABG (p < 0.0001) and PCI (p < 0.0001). The CABG compared with PCI also showed lower cost (p < 0.0001). The adjusted costs for \"survival free of clinical events and angina\" were US$25,690.00 for MT; US$45,989.00 for PCI and US$27,920.00 for CABG; with a significant difference between the 3 groups (p < 0.0001). Comparing the groups, it can be seen a lower cost in the medical treatment group, compared with CABG (p < 0.0001), and also in comparison with PCI (p < 0.0001). However, the comparison between the medical treatment group and surgical treatment group showed no significant difference (p=0.5613). Conclusion: The long-term comparative economic analysis revealed that PCI showed up to be the least cost-effective treatment. The medical treatment was the most cost-effective in \"events prevention\", but considering \"events and angina prevention\", it had a cost-effectiveness similar to surgical treatment

Texto completoBACKGROUND: The therapeutic options for multivessel coronary artery disease are coronary artery bypass graft surgery (CABG), percutaneous coronary intervention (PCI), or medical treatment alone (MT). These three therapeutic strategies present similar efficacy for specific subgroups. At the present moment, economic outcome trials are scant, and contemplate comparative cost between surgical or percutaneous intervention. OBJECTIVE: To analyze, prospectively, the comparative cost from three therapeutic strategies in multivessel coronary artery disease, at 5-year of follow-up. METHODS: We analyzed cumulative costs of 611 patients from clinical trial The Second Medicine, Angioplasty, or Surgery Study (MASS II). The economic analysis is based on remuneration provided by the supplementary health system of the Heart Institute of the Clinical Hospital of FMUSP, expressing these values in Brazilian currency. It was compared to the cumulative costs of each therapeutic strategy in the 5-year follow-up period. A cost-effectiveness analysis was then conducted for event-free survival and event plus angina-free survival. Cost-effectiveness analysis was performed by quality-adjusted life- year (QALY) analysis. RESULTS: Respectively, for event-free survival and event plus angina-free survival, MT presented 3.79 quality-adjusted life-years (QALY) and 2.07 QALY; PCI presented 3.59 and 2.77 QALY; and CABG demonstrated 4.4 and 2.81 QALY. The event-free costs were R$ 16327.80 for MT; R$ 35940.60 for PCI; and R$ 32873.40 for CABG. The paired comparison of the event-free costs showed that there was a significant difference favoring MT versus PCI (P < 0.01) and versus CABG (P < 0.01) and CABG versus PCI (P =0.01). The event-free plus angina-free costs were R$ 29795.40, R$ 46495.80 e R$ 44305.20, respectively. The paired comparison of the event-free plus angina-free costs showed that there was a significant difference favoring MT versus PCI (P =0.04), and versus CABG (P < 0.001); there was no difference between CABG and PCI (P > 0.05). CONCLUSION: The comparative analysis among the different therapeutic strategies demonstrated that MT was more cost-effective than CABG, and this than PCI
