Abstract:

Las enfermedades cardiovasculares son una de las causas más comunes de muerte en todo el mundo y son responsables de más del 30% de la mortalidad en los países desarrollados. Las enfermedades cardiovasculares causan la muerte, la discapacidad y una pesada carga económica para la sociedad y el sistema de seguro de salud. La metodología utilizada para el presente trabajo de investigación, se enmarca dentro de una revisión bibliográfica de tipo documental, ya que nos vamos a ocupar de temas planteados a nivel teórico como es Injerto de derivación coronaria. La técnica para la recolección de datos está constituida por materiales electrónicos, estos últimos como Google Académico, PubMed, entre otros, apoyándose para ello en el uso de descriptores en ciencias de la salud o terminología MESH. La información aquí obtenida será revisada para su posterior análisis. Las enfermedades coronarias siguen teniendo una prevalencia importante a nivel mundial, dada a las altas mortalidades asociadas a las diferentes patologías que se pueden generar como consecuencia de las enfermedades del corazón. La derivación coronaria o bypass coronario como técnica quirúrgica empleada para la resolución de esta patología gracias a la utilización de injertos, ha sido fundamental para reducir las tasas de mortalidades y prolongar la vida de pacientes con estas afecciones, proporcionándoles una mejor calidad de vida; el proceso quirúrgico como tal es complejo y delicado y no está exento de complicaciones, sin embargo, las tasas de éxito son elevadas a la par de que existen varios tipos de injertos con excelentes resultados, que su escogencia dependerá de cada caso.

Abstract:

In this paper we present a new approach in the study of Aorto–Coronaric bypass anastomoses configurations. The theory of optimal control based on adjoint formulation is applied in order to optimize the shape of the zone of the incoming branch of the bypass (the toe) into the coronary. The aim is to provide design indications in the perspective of future development for prosthetic bypasses. With a reduced model based on Stokes equations and a vorticity functional in the down field zone of bypass, a Taylor-like patch is found. A feedback procedure with Navier–Stokes fluid model is proposed based on the analysis of wall shear stress and its related indexes such as OSI.

Abstract:

La cirugía de Bypass coronario es un procedimiento quirúrgico en el tratamiento de la cardiopatía isquémica, con implicaciones psicológicas relevantes tras la cirugía, como el desarrollo de sintomatología ansiosa y depresiva que influyen en la calidad de vida relacionada con la salud del paciente, sin embargo, mediante el fortalecimiento de factores protectores como el optimismo disposicional, se mostró que es posible disminuir el impacto que genera la cirugía de bypass coronario. El objetivo del estudio fue identificar el papel que juega la calidad de vida en la interacción de factores de riesgo y protección tras la cirugía.

Abstract:

Absztrakt Az arteria pulmonalis törzsből eredő bal arteria coronaria ritka fejlődési rendellenesség, amely a súlyos balkamra elégtelenség miatt, kezeletlenül csecsemőkorban 85%-os halálozással jár. Sebészi kezelésének módozatait illetően a kórosan eredő ér lekötését, (esetleg kiegészítve az arteria subclavia – bal arteria coronaria bypass készitésével), a bal coronaria szájadék aortába történő implantálása váltotta fel. Egy 20 hónapos kisded esetét ismertetik, akinél a coronaria szájadék átültetése technikai okok miatt nem volt lehetséges, ezért azt az aorto-pulmonalis fenestratio és arteria pulmonalis törzsben kialakított tunel készítésével kapcsolták az aortához. A műtét sikerét a jó korai eredmények igazolják. Ez az első sikeres Takeuchi-műtét hazánkban.

Abstract:

Az ischaemiás szívbetegség gyógyításában meghatározó jelentőségű coronaria-bypassműtétek során a szerzők leggyakrabban vena saphena magna graftot használnak az áthidalásokhoz. Tekintettel a betegek növekvő életkorára, a több társbetegségre, a rosszabb általános állapotra, alapvető jelentőségű a lehető legkisebb sebfelület kialakítása az ilyen műtétek alatt. Célkitűzés: A vizsgálatok célja az endoszkópos saphenakivétel által adott lehetőségek felmérése, illetve az így nyert saphenagraft minőségének megítélése volt. Módszer: A szerzők 24 betegnél használtak endoszkópos technikát a vena saphena kivételére coronaria-bypassműtét vagy kombinált billentyű-coronaria bypassműtét során. A kivett vénából szövettani vizsgálatra 10 alkalommal küldtek mintát a vena-endothel megítélésére. Eredmények: Sebszövődmény a módszer alkalmazása után nem volt. A kivett vénaszakaszokat a műtétek során felhasználták, két esetet kivéve, amikor a véna kis kaliberűnek bizonyult. A szövettani vizsgálat minden esetben a véna ép endothelrétegét igazolta. Következtetés: Az endoszkópos technika jól alkalmazható a vena saphena eltávolítására bypassműtétek során. Alkalmazásának a szerzők jelenlegi gyakorlatában határt szab az egyelőre hosszabb műtéti idő (amely a későbbiekben remélhetőleg rövidülni fog).

Abstract:

A spontán coronaria dissectio ritka kórállapot, amely főleg nőkben, gyakran a peripartum időszakában fordul elő. Specifikus kóroki tényező egyértelműen nem azonosítható e nemritkán fatális kimenetelű betegség hátterében. Bemutatjuk egy fiatal, egy hete szült nőbetegünk esetét, aki mellkasi fájdalom miatt került kórházba, és akut ST-elevációs szívinfarktus EKG-jeleit észlelték rajta. A sürgősségi koronarográfia elzáródás nélküli nem szignifikáns szűkületeket észlelt, emiatt intervenció nem történt. Cardiogen sokk alakult ki, amely mechanikus keringéstámogatás segítségével rendeződött, a beteg állapota stabilizálódott, majd ismételt ischaemiás tünetei jelentkeztek, az újabb angiográfia már egyértelmű coronaria dissectio jelenlétét mutatta a bal közös törzs distalis részén, amely már a ramus circumflexus áramlást is limitálta, emiatt urgens coronaria bypass műtét történt jó eredménnyel. A spontán coronaria dissectióra gondolnunk kell a peripartum időszakában kialakult akut coronariaszindrómák esetén, melyek halálozása magas, kezelésében speciális szempontokat kell figyelembe vennünk.

Abstract:

Kawasaki Disease (KD) is an immunological disease which affects mainly children and young adolescents. This disease has its own challenges; mainly diagnosis and subsequently the importance of starting treatment early to prevent coronary artery disease later on in their life. This case report intends to describe a young adolescent who was diagnosed late, and eventually developed coronary artery disease. This study also highlights the angiographic changes that can be observed in the coronaries. In this case, the patient underwent coronary artery bypass surgery (CABG), utilizing bilateral internal mammary arteries.

Abstract:

Mechanical coronary artery occlusion is required for minimally invasive direct coronary artery bypass and off-pump coronary artery bypass surgery. It is important that the method of occlusion be minimally traumatic. Chronic effects of these methods have never been studied. Temporary occlusion of coronaries utilizing suture snare, silastic loop snare, and bulldog clamp was carried out in 12 Yucatan pigs. Three animals each were sacrificed acutely and at 3, 6, and 12 months. The area of occlusion of each vessel was examined by light microscopy and the degree of damage recorded. In the animals sacrificed acutely, there was more damage using the suture snare than with the other 2 methods, but there was minimal damage at longer intervals. There was slight damage acutely and chronically with the bulldog technique. No damage was seen acutely with the silastic loop technique, but some late damage was found. The techniques of coronary artery dissection and occlusion used for minimally invasive and off-pump bypass surgery may contribute to early postoperative graft occlusion.

Abstract:

Background To study the effect of nitecapone, a novel antioxidant, on cardiac neutrophil activation during cardiopulmonary bypass in patients. Methods In a double-blind, placebo controlled trial, 30 male patients undergoing coronary artery bypass grafting were randomly assigned to control (crystalloid cardioplegia, n = 15) and nitecapone groups (cardioplegia supplemented with nitecapone, n = 15). Leukocyte differential counts, neutrophil and monocyte CD11b and L-selectin expressions and neutrophil hydrogen peroxide production were measured in blood samples parallelly obtained from the coronary sinus and aorta before cardiopulmonary bypass and at 1, 5, and 10 min after aortic declamping. Myocardial myeloperoxidase activity was analyzed in biopsies taken at 1, 5, and 10 min after declamping. Results Transcoronary neutrophil difference (i.e., aorta--sinus coronarius) at 1 min after aortic declamping was significantly lower in nitecapone-treated patients (0.41 [-0.42-0.98] x 10(9) cells/l) than in controls (0.68 [-0.28-2.47] x 10(9) cells/l; P = 0.032). At 5 min after aortic declamping, significant transcoronary reduction of neutrophil hydrogen peroxide production and CD11b expression were observed in controls but not in nitecapone patients. At 24 h postoperatively, left ventricular stroke volume was better in nitecapone-treated patients (94 [51-118] ml) than controls (66 [40-104] ml; P= 0.018). Data are median [range]. Conclusion Nitecapone added to cardioplegia solution reduces cardiac neutrophil accumulation and transcoronary neutrophil activation during clinical cardiopulmonary bypass. Reflected by better left ventricular stroke volume, nitecapone treatment may be an additional way of reducing the deleterious effects of neutrophil activation during cardiopulmonary bypass.

Abstract:

Objective The commercially available C-Port distal anastomotic device (Food and Drug Administration cleared in 2007) is an automated miniature vascular stapler that performs the coronary anastomosis. This prospective multicenter registry sought to evaluate midterm patency using this device compared with hand-sewn grafts. Methods Patients receiving at least one C-Port anastomosis during coronary artery bypass grafting surgery were enrolled at eight sites. Of the 117 patients enrolled, 78 patients (67%) with 104 C-Port vein grafts completed the study to patency assessment via computed tomography angiography. Clinical follow-up and index graft patency (Gated 64-slice computed tomography scan) were performed at least 12 months postoperatively. The primary efficacy endpoint was patency compared with the peer-reviewed results from the PRoject of Ex-vivo Vein graft ENgineering via Transfection IV (PREVENT IV) trial. Results The patient population was consistent with the PREVENT IV placebo cohort. The mortality at 12 months was 0.85% (1/117). The major cardiac morbidity rate was 3.4% (4/117). The C-Port vein graft occlusion rate was 16.3% (17/104) compared with 26.6% (597/2242) in the PREVENT IV trial ( P = 0.011). Within this study, C-Port graft occlusion rates were not significantly different from the hand-sewn grafts ( P = 0.821). Conclusions The C-Port device is safe and effective in creating the distal anastomosis with equivalent patency rates to hand-sewn grafts at 12 months. When compared with hand-sewn anastomoses from a recent large prospective trial, the C-Port device demonstrated a statistically significant reduction in midterm graft occlusion. Further studies are required to evaluate its effect in less invasive coronary surgery.

Abstract:

Background: Coronary artery bypass grafting (CABG) continues to be the best standard in the management of severe coronary artery disease (CAD), providing good symptom management and life extension. Although CABG was first performed by reversed saphenous veins (SVGs), surgeons have increasingly adopted arterial conduits because of their longer-term patency and resistance to atherosclerosis. CABG's efficacy may potentially be affected by the extension of atherosclerosis in the native coronary arteries. Few researches have investigated the long-term angiographic disease progression of native coronary arteries after surgical revascularization, or the variables that may impact this progression. Proximal native disease progression was presented to be two to six times more common than distal disease progression, with greater rates of progression in coronaries bypassed by SVGs than arterial grafts. The goal of this research was to determine influence of CABG on the extension of native coronaries atherosclerosis. Methods: This prospective study was established on 25 patients who were diagnosed to have ischemic heart disease in cardiothoracic surgery department in Faculty of Medicine Menoufia University. Results: The study showed that according to the risk factors among the studied cases, smoking was (60%), Dyslipidemia was (32%), HTN was (32%) and Diabetes was (32). According to grafts in proximal lesions, there was progression of atherosclerosis up to total occlusion, but in Distal lesions, there was significant regression of atherosclerosis. As result, there was statistically significant difference between proximal with distal lesions. Also, study showed that there was a significant difference between left system (LAD, D, OM) in comparison with right system (PDA) regarding distal lesion. Our results showed that univariate logistic regression analysis for progression in distal lesion regarding Dyslipidemia and Diabetes. Conclusion: Progression of disease is more evident in coronary segment proximal to anastomosis, while regression of disease is more evident in coronary segment distal to anastomosis with statistically significant difference between them, also the risk of disease progression post CABG was found to be multifactorial, as certain risk factors can affect progression of the disease as Diabetes mellitus and dyslipidemia that were of statistically significance.

Durante una clase de disección de pre-grado de la extremidad inferior se encontró una doble vena safena magna unilateral en el miembro inferior izquierdo de un cadáver masculino. La incidencia de esta variación fue del 1,3% de todos los especímenes muestra. En este trabajo se reporta la variabilidad del drenaje venoso de las extremidades inferiores para mejorar la conciencia para los radiólogos vasculares y proporcionar además una opción adicional en la cirugía de bypass de la arteria coronaria para evitar las várices iatrogénicas. A double great saphenous vein has been associated with varicosity in a number of studies. During routine undergraduate dissection of the lower limb a unilateral double great saphenous was found in the left lower limb of a male cadaver. The incidence of this variation was 1.3% of all specimens. This paper reports the variability of lower limb venous drainage to increase the awareness for vascular radiologists and provide further an additional option in coronary artery bypass surgery to avoid iatrogenic varicosity.

Abstract:

Il trattamento delle sindromi coronariche croniche (SCC) è ancora oggi influenzato dai risultati di vecchi trials di confronto fra bypass aortocoronarico e terapia medica, condotti negli anni ’70 e da studi osservazionali. Da questi studi era emersa la superiorità della rivascolarizzazione chirurgica o percutanea sulla mortalità, rispetto alla gestione conservativa, nei pazienti ad alto rischio anatomico o ischemico. Parallelamente alle nuove acquisizioni patogenetiche, che hanno accertato la natura multifattoriale delle SCC e contemporaneamente allo sviluppo dei moderni farmaci in grado di incidere positivamente sull’outcome delle malattie cardiovascolari, una serie di studi controllati ha confrontato in tempi più recenti la terapia medica ottimale (OMT) con la rivascolarizzazione, accertando l’assenza di benefici incrementali delle strategie invasive, rispetto alle strategie conservative, nei pazienti con SCC. Il trasferimento di queste nuove evidenze dalla teoria alla pratica è tuttavia lento ed insufficiente e la quasi totalità dei pazienti con SCC è ancora oggi trattato invasivamente, in deroga ai principi di appropriatezza e di rispetto delle raccomandazioni delle linee guida. ARCA Registry, uno studio osservazionale, prospettico, progettato e condotto dalla Società Scientifica A.R.C.A., ha accertato l’efficacia e la sicurezza di un modello di gestione dell’angina stabile, raccomandato dalle linee guida e consistente nella OMT quale trattamento inziale in tutti i pazienti ed il ricorso selettivo ed individualizzato alla coronarografia e alla rivascolarizzazione solo nei pazienti non responsivi o ad alto rischio. I risultati di ARCA Registry dovrebbero facilitare il trasferimento alla pratica clinica delle nuove evidenze, migliorando l’appropriatezza gestionale delle SCC.

Abstract:

Introducción: la revascularización temprana ha reducido la presencia de complicaciones mecánicas del infarto agudo de miocardio; la comunicación interventricular suele ocurrir entre el tercer y quinto día después del infarto. Se presenta el caso de un paciente poco usual y en quien los síntomas predominantes fueron principalmente gástricos. Descripción: paciente masculino de 65 años, con historia de hipertensión arterial, tabaquismo activo y consumo frecuente de alcohol, quien consultó por síntomas gastrointestinales y dolor torácico de características atípicas. En el examen físico se encontró un soplo holosistólico de predominio en los focos de la base. El electrocardiograma documentó QS en pared inferior, sin alteraciones del segmento ST-T, biomarcadores positivos y el ecocardiograma encontró disfunción sistólica, aneurisma del segmento basal y medio de la pared inferior con comunicación interventricular con flujo de izquierda a derecha. Fue llevado a coronariografía diagnóstica encontrándose enfermedad severa de dos vasos y luego fue intervenido quirúrgicamente para corrección de aneurisma ventricular, comunicación interventricular y bypass coronario. Conclusión: reconocer las manifestaciones clínicas atípicas del infarto agudo de miocardio y un examen físico bien realizado permiten identificar problemas muy serios, como las complicaciones mecánicas del infarto.

Abstract:

Aim To evaluate the feasibility of robotically enhanced preparation of internal mammary arteries (IMA). Method Via three trocars in left thoracic wall the left, right or both IMA were skeletonized under CO2 insufflation and single lung ventilation using electrocautery. Results In 12 months, 26 LIMA, five BIMA and one RIMA were dissected. In five patients, the procedure had to be determined (IMA injury (two), respiratory insufficiency (two), and heart penetration (one)). Mean intrathoracic pressure was 9.7 ± 1.5 mmHg. Mean time for LIMA and RIMA dissection was 66.7 ± 21.1 and 99.2 ± 8.7 min, respectively. In 10 patients, pericardium was incised and course of LAD assessed. However, in two patients, this coronary did not correlate with LAD. Time for instrument change depended on type of tool (cautery blade: 24.9 ± 13.1 s, clip applier 72.8 ± 28.4 s). Conclusion Robotic dissection of IMA is reasonable. However, life-threatening complications can barely be managed due to inadequate tools and excessive time for instrument change. Incorrect determination of coronaries can result in misplaced anastomoses.

Abstract:

Absztrakt: A tünetes koszorúér-betegség kezelésében ma is kiemelkedő szerepet játszanak a revascularisatiós műtétek (coronary artery bypass grafting – CABG). Az első beavatkozások elvégzése óta eltelt több mint ötven év alatt számos klinikai megfigyelés igazolja, hogy a koszorúér-áthidalásra az arteria mammaria interna (IMA) használható a legkedvezőbb eredménnyel. Az IMA szövettani struktúrája és élettani tulajdonságai ellenállóvá teszik az eret az érelmeszesedéssel szemben. Cikkünkben a Magyarországon IMA-graft felhasználásával elsőként végzett CABG-műtétről emlékezünk meg, egyúttal az IMA kedvező tulajdonságait az irodalomban eddig közölt leghosszabb (harmincöt éves) utánkövetéses coronarographia eredményeivel illusztráljuk. Az eset alátámaszthatja azt a feltételezést is, hogy a mammariagraft prosztaciklintermelése megvédi a kiáramlási pályát az atherosclerosis progressziójától. Ennek igazolására nagy esetszámú vizsgálat javasolható, amely sztentimplantációval hasonlítaná össze az IMA-graft feltételezhető védőhatását a kiáramlási pályán. A hosszú távú követés során a bal coronaria elülső leszálló ágának (LAD) sztentelését versus az arteria mammaria interna graftnak a felhelyezését követően a LAD kiáramlási pályájának alakulását kellene értékelni.

Abstract:

The choice of the surgical technique and quality of surgical repair determine the cardiac outcome of Tetralogy of Fallot(TOF) with anomalous coronary artery(ACA). On the other hand, the type of surgical reconstruction depends on the size of pulmonary annulus and the exact location of ACA in relation to pulmonary annulus.A unified repair strategy that limits and balance between postoperative residual pulmonary stenosis(PS) and pulmonary insufficiency (PI) after patch enlargement is critical for preservation of ventricular function with or without deliberate sacrifice of ACA In condition of inadvertent transaction or necessiate sacrefice of ACA during right ventricular outflow tract obstruction (RVOTO) repair needs urgent coronary artery bypass grafting (CABG) using left internal mamary artery(LIMA)/autologous venous conduit to prevent myocardial infarction.

Abstract:

Objetivo: Evaluar el nivel de independencia funcional de los pacientes sometidos a cirugía cardiaca durante su proceso de recuperación. Materiales y Método: Investigación con enfoque cuantitativo y estudio de tipo analítico longitudinal prospectivo. La población de estudio estuvo conformada por personas mayores de 18 años, sometidas a cirugía cardiaca programada, en una institución de salud de la ciudad de Medellín, Colombia. Se aplicó un cuestionario para las variables sociodemográficas y el procedimiento quirúrgico, además se utilizó el instrumento de independencia funcional de Granger y Hamilton traducido al español por Paolinelli. Se realizó un análisis univariado, bivariado y se usó la regresión de la mediana como prueba multivariada no paramétrica. Resultados: El total de participantes fue de 33. El 50% tenía 64 años. El 66.7% fueron hombres. Se encontró que el 57.6% eran hipertensos y el 12.1% diabéticos. El 54.5% se sometió a bypass coronario. Se evidencia una diferencia estadísticamente significativa entre cada una de las mediciones de la independencia funcional (p<0.05) y una relación directa entre la edad y la disminución de la autonomía (p 0.034). Conclusiones: La independencia funcional se afecta tras la realización de la cirugía cardiaca, pero se recupera con el paso del tiempo y está de alguna manera relacionada con la edad.

Abstract:

We are representing a case of successful retrograde recanalization of a chronic ostial occlusive lesion of the left main coronary artery (LMCA) via a saphenous vein graft. A 70-year-old male patient, with a history of previous (3 years ago) coronary artery bypass surgery, was evaluated with coronary angiography because of his recent anginal symptoms. Left main coronary artery could not be visualized from the aortic root. It could be visualized with drilled balloon technique which was introduced retrogradely from a saphenous vein graft, and the chronic ostial lesion of the LMCA could be treated with balloon dilatation and stenting. Coronary occlusions can be treated retrogradely via the native collaterals and grafts. The coronaries that are not visualized with an antegrade fashion can be visualized with a retrograde way with the drilled balloon introduced through a patent graft. We could not find any publication about this technique on the web-based research. When encountered with a totally occluded ostial lesion of the LMCA, that cannot be visualized even from the aortic root, it may be tried to be visualized through a patent graft retrogradely. This is a safe and reliable method in patients with a total occlusion of the LMCA who also have a patent saphenous vein graft.

Abstract:

Hybridization in flowering plants depends, in the first place, on the delivery of pollen to a receptive stigma and the subsequent growth of pollen tubes through the style to the ovary, where the sperm nucleus of the pollen grain can ultimately fertilize the egg cell. However, reproductive failure is often observed in distant crosses and is caused by pre- and/or post-zygotic barriers. In this study, the reproductive pre-fertilization barriers of intertribal crosses between Anemone coronaria L. and Ranunculus asiaticus L., both belonging to the Ranunculaceae, were investigated. Despite the incongruity of intertribal crosses between A. coronaria and R. asiaticus having been of low intensity at the stigmatic level, interstylar obstructions of the pollen tube growth occurred, which confirmed the presence of pre-fertilization barriers. We show that these barriers could be partially bypassed by combining pollination with a stigma treatment. More specifically, a significantly higher ratio of the pollen tube length to the total style length and a better seed set were observed when the stigma was treated with the auxin 2,4-dichlorophenoxyacetic acid (2,4-D, 1 mg·mL−1) together with the cytokinin kinetin (KIN, 0.5 mg·mL−1) 24 h after pollination, irrespective of the cross direction. More specifically, the stigma treatments with any form of auxin (combined or not combined with cytokinin) resulted in a full seed set, assuming an apomictic fruit set, because no pollination was needed to obtain these seeds.

Abstract:

Epitranscriptomic modifications in RNA can dramatically alter the way our genetic code is deciphered. Cells utilize these modifications not only to maintain physiological processes, but also to respond to extracellular cues and various stressors. Most often, adenosine residues in RNA are targeted, and result in modifications including methylation and deamination. Such modified residues as N-6-methyl-adenosine (m6A) and inosine, respectively, have been associated with cardiovascular diseases, and contribute to disease pathologies. The Ischemic Heart Disease Epitranscriptomics and Biomarkers (IHD-EPITRAN) study aims to provide a more comprehensive understanding to their nature and role in cardiovascular pathology. The study hypothesis is that pathological features of IHD are mirrored in the blood epitranscriptome. The IHD-EPITRAN study focuses on m6A and A-to-I modifications of RNA. Patients are recruited from four cohorts: (I) patients with IHD and myocardial infarction undergoing urgent revascularization; (II) patients with stable IHD undergoing coronary artery bypass grafting; (III) controls without coronary obstructions undergoing valve replacement due to aortic stenosis and (IV) controls with healthy coronaries verified by computed tomography. The abundance and distribution of m6A and A-to-I modifications in blood RNA are charted by quantitative and qualitative methods. Selected other modified nucleosides as well as IHD candidate protein and metabolic biomarkers are measured for reference. The results of the IHD-EPITRAN study can be expected to enable identification of epitranscriptomic IHD biomarker candidates and potential drug targets.

Abstract:

Introducción: La enfermedad renal crónica (ERC) es una patología con incremento en la frecuencia en la población de adultos mayores de 80 años o más en México en los últimos años. Las complicaciones y pronóstico de la enfermedad en esta población son desconocidos. Objetivo: Conocer la frecuencia de complicaciones, tiempo y causas de muerte y pronóstico de pacientes mayores de 80 años que inician Hemodiálisis (HD). Material y métodos: Estudio retrospectivo, transversal, observacional con una muestra de 30 pacientes mayores de 80 años con inicio de HD de enero 2014 a enero del 2017. Resultados: La sobrevida de los pacientes aumentó hasta ocho meses en pacientes sometidos a HD en comparación con aquellos pacientes que se trataron en forma conservadora. El 80% de los pacientes que ingresaron a HD murieron en los primeros 12 meses. Las principales causas de muerte fueron procesos infecciosos asociados a catéter de HD, infarto agudo de miocardio y enfermedad vascular cerebral (EVC) hemorrágico. Los antecedentes cardiovasculares demostraron ser de suma importancia, al aumentar la probabilidad del riesgo de muerte hasta 4 veces durante los primeros 12 meses. Conclusiones: Se obtuvo evidencia de aumento de probabilidad de muerte en el primer año de HD en pacientes mayores de 80 años que presentan antecedentes enfermedad coronaria (IAM, angioplastía y bypass), tabaquismo, EVC con hemiplejía, hipertrofia ventricular izquierda (HVI) por ECOTT y uso de catéter de hemodiálisis.
