Abstract:
Background: Knowledge is limited concerning the type of symptoms and the time from onset of symptoms to first medical contact at first and second myocardial infarction in the same patient. Aim: This study aimed to describe the type of symptoms and the time from onset of symptoms to first medical contact in first and second myocardial infarctions in men and women affected by two myocardial infarctions. Furthermore, the aim was to identify factors associated with prehospital delays ≥2 h at second myocardial infarction. Methods: A retrospective cohort study with 820 patients aged 31–74 years with a first and a second myocardial infarction from 1986 through 2009 registered in the Northern Sweden MONICA registry. Results: The most common symptoms reported among patients affected by two myocardial infarctions are typical symptoms at both myocardial infarction events. Significantly more women reported atypical symptoms at the second myocardial infarction compared to the first. Ten per cent of the men did not report the same type of symptoms at the first and second myocardial infarctions; the corresponding figure for women was 16.2%. The time from onset of symptoms to first medical contact was shorter at the second myocardial infarction compared to the first myocardial infarction. Patients with prehospital delay ≥2 h at the first myocardial infarction were more likely to have a prehospital delay ≥2 h at the second myocardial infarction. Conclusions: Symptoms of second myocardial infarctions are not necessarily the same as those of first myocardial infarctions. A patient’s behaviour at the first myocardial infarction could predict how he or she would behave at a second myocardial infarction.

Abstract:
The aim of the work is to examine the features of recovery of lost neurological functions and the quali ty of life of patients with acute vertebrobasilar infarction, to evaluate and compare the short-term and long-term outcome of a stroke depending on the aff ected intracranial anatomical areas of the posterior circulation basin. 120 patients with acute vertebrobasilar infarction were examined, among them 22 (18.3 %) patients had a cerebral infarction, 38 (31.7 %) — pontine infarction, 13 (10.8 %) — midbrain infarction, 22 (18.3 %) — thalamic infarction and 25 (20.8 %) patients — cerebellar infarction. Strokes were distributed into three intracranial anatomical territories of the posterior circular basin: proximal, medial, distal. The diagnosis was established on the basis of data from the neurological clinic and magnetic resonance imaging in standard and DV modes. Clinical and neurological comparisons and a comparative statistical analysis of the functional outcomes of infarctions on the 21st and 90th day of a prospective observation. Despite the fact that there is no clear functional boundary between the proximal, medial and distal intracranial anatomical territories of the posterior circulation basin, which once again confi rms their functional unity, the potential for resuming lost neurological functions, a short-term and long-term outcome after infarction of diff erent anatomical and topographic areas of posterior circulation basin do not always match. Statistical analysis pointed that the short-term and long-term functional outcome after a infarction in diff erent intracranial vascular territories of the posterior circulation basin had certain features of the evolution of functional and neurological recovery. In particular, cerebellar infarctions had a signifi cantly better functional outcome compared to infarctions of the medulla oblongata in the short and long term perspective and midbrain infarctions — on the 90th day of the prospective observation (p <0.05). Paired comparisons of functional consequences between cere bellar, pontine and thalamic infarction did not reveal a statistically signifi cant (p > 0.05) correlation between factorial and eff ective signs during short-term and longterm follow-up.

Abstract:
OBJECTIVE Young patients with moyamoya disease can exhibit infarction after revascularization surgery. This analysis of the characteristics of infarction after encephaloduroarteriosynangiosis (EDAS) in young patients with moyamoya disease was undertaken in an effort to elucidate the infarction mechanism. METHODS The authors retrospectively collected clinical information and reviewed pre- and postoperative MRI studies from cases involving patients younger than 18 years who underwent EDAS for the treatment of moyamoya disease between January 2012 and February 2015. Infarction patterns were categorized into watershed, territorial, or mixed pattern. The Wilcoxon rank sum test, chi-square test, and Fisher exact test were used to compare the clinical and imaging variables between patient groups. The characteristics of patients with and without postoperative infarction were compared using univariate and multivariate analysis. The cumulative proportion of patients without postoperative infarction according to operation stage was calculated using the Kaplan-Meier method and the resulting curves were compared using the log-rank test. RESULTS In 100 patients, 171 EDAS procedures had been performed. There were 38 cases of preoperative infarction in 35 patients and 20 cases of postoperative infarction in 13 patients. Territorial infarction was more frequent in the postoperative infarction group than in the preoperative infarction group (55.0% vs 37.8%, p = 0.037). Infarction was more common on the bilateral or contralateral side of the operation after first-stage EDAS (9 [75.0%] of 12 infarctions) than in the second-stage operation (2 [25.0%] of 8 infarctions), but the difference was not statistically significant (p = 0.068). The frequency of postoperative infarction was not significantly different depending on the stage of the operation (p = 0.694). CONCLUSIONS An acute infarction pattern after EDAS was more frequently territorial, suggesting an underlying occlusive mechanism. Operation stage did not affect the rate of postoperative infarction occurrence.

Abstract:
Objective. To determine whether there is an association between smoking and the location of acute myocardial infarctions. Methods. Using a cohort from our hospital and published cohorts from Ireland, Uruguay, and Israel, we calculated odds of having an inferior wall as opposed to an anterior wall acute myocardial infarction among smokers and nonsmokers. Results. In our cohort, there was a higher proportion of smokers than nonsmokers in patients with inferior acute myocardial infarctions than in patients with anterior infarctions. This difference was also present in each of the other cohorts. Odds ratios for an inferior versus an anterior acute myocardial infarction among smokers ranged from 1.15 to 2.00 (median odds ratio, 1.32). When the cohorts were combined (), the pooled odds ratio for an inferior as opposed to an anterior acute myocardial infarction among smokers was 1.38 ( confidence interval, 1.20 to 1.58) (). Conclusions. Cigarette smoking increases the risk of inferior wall acute myocardial infarction more than the risk of anterior wall infarction. Smoking thus appears to adversely affect the right coronary arterial circulation to a greater extent than the left coronary arterial circulation by a mechanism not yet understood.

Abstract:
Bacground. Association of both cerebral infarction and acute bacterial meningitis is more common in younger patients than in the elderly. The rate of mortality and the frequency of sequel are very high inspite of the use of modern antibiotic therapy. In more than 30% of the cases of childhood bacterial meningitis, both arterial and venous infarctions can occur. The aim of this study was to present the role of the use of magnetic resonance (MRI), and MR angiography (MRA) in the detection of bacterial meningitis in children complicated with cerebral infarctions. Method. In the Centre for MR, the Clinical Centre of Serbia, 25 patients with the diagnosis of bacterial meningitis, of which 9 children with cerebral infarction whose clinical conditon deteriorated acutely, despite the antibiotic therapy, underwent MRI and MR angiography examination on a 1T scanner. Examination included the conventional spin-echo techniques with T1-weighted saggital and coronal, and T2- weighted axial and coronal images. Coronal fluid attenuated inversion recovery (FLAIR) and the postcontrast T1-weighted images in three orthogonal planes were also used. The use MR angiography was accomplished by the three-dimensional time-of-flight (3D TOF) technique. Results. The findings included: multiple hemorrhagic infarction in 4 patients, multiple infarctions in 3 patients, focal infarction in 1 patient and diffuse infarction (1 patient). Common sites of involvement were: the frontal lobes, temporal lobes and basal ganglia. The majority of infarctions were bilateral. In 3 of the patients empyema was found, and in 1 patient bitemporal abscess was detected. In 8 of the patients MR angiography confirmed inflammatory vasculitis. Conclusion. Infarction is the most common sequel of severe meningitis in children. Since the complication of cerebral infarction influences the prognosis of meningitis, repetitive MRI examinations are very significant for the evaluation of the time course of vascular involvement. The use of MRI, especially FLAIR imaging, confirmed its value in the detection and determination of the site and the extent of cerebral infarction. Non-invasive technique of examination, 3D TOF MR angiography clearly should show the presence of inflammatory vasculitis.

Abstract:
Spinal cord infarctions are rare. They are difficult to diagnose clinically and remain undiagnosed even after extensive investigations. Magnetic Resonance (MR) features include hyperintensity of the cord on T2W images. Few cases of spinal cord infarction associated with vertebral body infarction are reported in the literature. We describe another five cases of spinal cord infarction with histopathological confirmation of the vertebral body signal changes. MR examinations of five patients who presented with acute spontaneous spinal cord syndrome were reviewed. Abnormal MR features of the spinal cord included signal changes within the parenchyma, best demonstrated on T2W images. These cord changes were associated with vertebral body T2 hyperintensity in all the patients and in one patient, the computed tomography guided biopsy of vertebral body lesion reported infarction. MR is sensitive to detect spinal cord infarctions and associated vascular and bony changes. The associated signal abnormalities in the bone marrow are a corroborative sign in the diagnosis of spinal cord infarction which was proved by histopathology.

Abstract:
Objective Our study focused on acute lacunar infarct shapes to explore the risk factors and clinical significance of irregularly shaped lacunar infarctions. Methods Based on the shape of their acute lacunar infarct, patients (n=204) were classified into the “regular” group or “irregular” group. The characteristics of the lacunar infarction were compared between the regular and irregular groups, between patients with and without neurological deterioration, and between patients with different modified Rankin scale (mRS) scores. The risk factors for irregularly shaped lacunar infarctions, neurological deterioration, and high mRS scores were identified. Results Blood pressure variability (BPV) was an independent risk factor for irregularly shaped lacunar infarction. Infarction size, prevalence of advanced leukoaraiosis, and irregularly shaped lacunar infarcts were independent risk factors for higher mRS scores. Conclusions The irregularly shaped lacunar infarcts were correlated with BPV. Irregularly shaped lacunar infarctions and leukoaraiosis may be associated with unfavorable clinical outcomes.

Abstract:
Splenic and renal infarctions are embolic conditions which usually occur secondary to cardiac problems, thromboembolic systemic diseases, and infectious conditions such as sepsis. Trauma is a relatively rare cause of visceral infarctions. Traumatic segmental renal infarction associated with total splenic infarction is extremely rare. For detecting these visceral infarctions, contrast-enhanced computed tomography is essential, and a very careful examination is required for detecting very small infarctions and excluding total visceral infarctions. In isolated splenic or renal infarctions secondary to trauma, the common contrast-enhanced computed tomography findings are wedge-shaped or segmental hypodense areas in kidneys or spleen and rarely total visceral infarctions. Usually, intraperitoneal or retroperitoneal fluid collection which corresponds to bleeding from kidney or spleen is not seen in such cases. Also, the lack of evidence of active extravasation from renal/splenic arteries and pseudoaneurysm or dissection is an important finding of isolated traumatic splenic or renal infarctions. Because total infarctions can be misinterpreted in some cases, differences in density between intra-abdominal organs allowed by computed tomography must be carefully examined. Intestinal infarctions, the other abdominal injuries, pulmonary injuries, and pelvic or thoracic bone fractures usually accompany traumatic renal or splenic infarctions. In this report, we present contrast-enhanced computed tomography findings of a multitrauma pediatric case of traumatic total splenic and bilateral segmental renal infarction by reviewing the literature.

Abstract:
OBJECTIVE Malignant internal carotid artery (ICA) infarction is an entirely different disease entity when compared with middle cerebral artery (MCA) infarction. Because of an increased area of infarction, it is assumed to have a poorer prognosis; however, this has never been adequately investigated. Decompressive craniectomy (DC) for malignant MCA infarction has been shown to improve mortality rates in several randomized controlled trials. Conversely, aggressive surgical decompression for ICA infarction has not been recommended. The authors sought to compare the functional outcomes and survival between patients with ICA infarctions and those with MCA infarctions after DC in the largest series to date to investigate this assumption. METHODS A multicenter retrospective review of 154 consecutive DCs for large territory cerebral infarctions performed from 2005 to 2020 were analyzed. Patients were divided into ICA and MCA groups depending on the territory of infarction. Variables, including age, sex, medical comorbidities, laterality of the infarction, preoperative neurological status, primary stroke treatment, and the time from stroke onset to DC, were recorded. Univariable and multivariable analyses were performed for the clinical exposures for functional outcomes (modified Rankin Scale [mRS] score) on discharge and at the 1- and 6-month follow-ups, and for mortality, both inpatient and at the 1-year follow-up. A favorable mRS score was defined as 0–2. RESULTS There were 67 patients (43.5%) and 87 patients (56.5%) in the ICA and MCA groups, respectively. Univariable analysis showed that the ICA group had a comparably favorable mRS (OR 0.15 [95% CI 0.18–1.21], p = 0.077). Inpatient mortality (OR 1.79 [95% CI 0.79–4.03], p = 0.16) and 1-year mortality (OR 2.07 [95% CI 0.98–4.37], p = 0.054) were comparable between the groups. After adjustment, a favorable mRS score at 6 months (OR 0.17 [95% CI 0.018–1.59], p = 0.12), inpatient mortality (OR 1.02 [95% CI 0.29–3.57], p = 0.97), and 1-year mortality (OR 0.94 [95% CI 0.41–2.69], p = 0.88) were similar in both groups. The overall survival, plotted using the Cox proportional hazard regression, did not show a significant difference between the ICA and MCA groups (HR 0.581). CONCLUSIONS Unlike previous smaller studies, this study found that patients with malignant ICA infarction had a functional outcome and survival that was similar to those with MCA infarction after DC. Therefore, DC can be offered for malignant ICA infarction for life-saving purposes with limited functional recovery.

Abstract:
Acute myocardial infarction (AMI) results in the activation of the innate immune system with monocytes playing critical roles in both the initial inflammation following myocardial ischaemia and subsequent recovery. Monocytes are a heterogeneous cell population and observations from experimental models demonstrate that immediately following myocardial injury, classical inflammatory monocytes, which are highly phagocytic, are recruited to ischaemic myocardium from the bone marrow and spleen and peak at 48 hours. This is followed by the recruitment of non-classical monocytes that are involved in repair and healing, peaking at day 5. The monocyte response in humans following AMI is currently poorly understood. Due to their central role in the pathogenesis of AMI, monocytes are attractive both as potential biomarkers to inform of extent of myocardial injury (and recovery) and also as therapeutic targets with the specific targeting of monocytes in experimental models resulting in reduced infarction size and improved LV remodelling. However, in spite of these promising results and our greater understanding of the pathogenesis of AMI, no immune-modulating therapeutic has been translated into routine clinical practice. We therefore hypothesized that characterisation of the monocyte response to AMI by flow cytometry and gene expression profiling in both experimental models and humans would give novel insights into underlying biological processes and function (both locally in the myocardium and systemically), identify novel therapeutic targets, enable their use as cellular biomarkers of disease, and test conservation between species validating the experimental model for future investigation. Classical inflammatory monocytes were found to significantly increase in the peripheral blood 48 hours following AMI in both mice and humans, with the magnitude of the monocyte response correlating with the extent of myocardial injury in both species. Gene expression profiling of peripheral circulating monocytes following AMI identified a number of candidate genes, biological pathways and upstream regulators that were conserved between species and that could represent novel therapeutic targets. Furthermore, in an experimental model of AMI, leukocytes appeared to have effects beyond the ischaemic myocardium, with leukocyte recruitment in remote myocardium and in kidneys associated with elevated inflammatory markers and endothelial activation.

Abstract:
This study was designed to discover the coping behaviours used by patients six to twelve months following a myocardial infarction (MI). The conceptualization of coping behaviours was based on the UBC Model for Nursing which directed the researcher to examine coping behaviours used to meet the patients' basic human needs. The specific research question was, "What new or already established coping behaviours have patients utilized after an MI in an attempt to satisfy their basic human needs?" Seven participants who had experienced an MI six to twelve months previously, were recruited from cardiologists. Data were collected from the participants during interviews using semi-structured open-ended questioning technique. Data were coded and analyzed using the constant comparative method developed by Glaser and Strauss. Three themes that emerged from the data were: 1) coping behaviours related to risk reduction, 2) coping behaviours related to returning to normal, 3) coping behaviours related to reaching a new normal. The findings supported the need for lifestyle changes involving the use of existing coping behaviours and/or the development of new coping behaviours to meet subjects' basic human needs. Certain unmet basic human needs were identified following an MI which required the development of new coping behaviours to meet them. Nurses are in a unique position to assist MI patients in developing coping behaviours to meet their basic human needs. The descriptions and explanations of coping behaviours identified in this study may serve as a useful guide for nurses to help patients deal with changes in their lives and develop necessary coping behaviours to meet their basic human needs.

Abstract:
Although previous research has pointed to worry as one of the highest causal attributions reported by MI patients, no studies have primarily investigated the concept of worry in this cohort. This study aimed to determine the prevalence of pathological worry in MI patients who reported worry as a causal factor to their MI (Experimental group), compared to MI patients that did not implicate worry as a causal attribute (Control group). A central hypothesis to this study was that higher pathological worry would be found in the Experimental group, and would be significantly associated with meta-worry (worry about worry), rather than health worry. The design was cross-sectional, and consisted of administering self-report questionnaires to a total of 34 post-MI patients (n=17 in each group). The questionnaire measured: pathological worry, meta-worry, anxiety, depression, and thought control strategies. Participants in the Experimental group were found to be significantly younger than the Control group, and a higher proportion were employed. The main results indicated that no differences were found between the two groups in terms of worries relating to their health. However, pathological worry, meta-worry, social worry, anxiety and the use of thought control strategies were significantly higher in the Experimental group, compared with the Control group. Interestingly, none of the participants (N=34) reported symptoms of depression at a clinical level. Further analysis revealed that pathological worry significant correlated with meta-worry and the thought control strategy known as 'Punishment'. In conclusion MI patients who rated worry highly as causal to their MI were also found to be more pathologically worried after their MI than participants who implicated physical factors as causal attributes. However, this pathological worry was not related to worry about health, but was regarded as a coping response that is best understood from a metacognitive model of a generalised anxiety disorder.

Abstract:
Background: This study aimed to evaluate the incremental prognostic value of infarct size, microvascular obstruction (MO), myocardial salvage index (MSI), and left ventricular ejection fraction (LV-EFCMR) assessed by cardiac magnetic resonance imaging (CMR) in comparison to traditional outcome markers in patients with ST-elevation myocardial infarction (STEMI) reperfused by primary percutaneous intervention (PCI). Methods: STEMI patients reperfused by primary PCI (n = 278) within 12 hours after symptom onset underwent CMR three days after the index event (interquartile range [IQR] two to four). Infarct size and MO were measured 15 minutes after gadolinium injection. T2-weighted and contrast-enhanced CMR were used to calculate MSI. In addition, traditional outcome markers such as ST-segment resolution, pre- and post-PCI Thrombolysis In Myocardial Infarction (TIMI)-flow, maximum level of creatine kinase-MB, TIMI-risk score, and left ventricular ejection fraction assessed by echocardiography were determined in all patients. Clinical follow-up was conducted after 19 months (IQR 10 to 27). The primary endpoint was defined as a composite of death, myocardial reinfarction, and congestive heart failure (MACE). Results: In multivariable Cox regression analysis, adjusting for all traditional outcome parameters significantly associated with the primary endpoint in univariable analysis, MSI was identified as an independent predictor for the occurrence of MACE (Hazard ratio 0.94, 95% CI 0.92 to 0.96, P <0.001). Further, C-statistics comparing a model including only traditional outcome markers to a model including CMR parameters on top of traditional outcome markers revealed an incremental prognostic value of CMR parameters (0.74 versus 0.94, P <0.001). Conclusions: CMR parameters such as infarct size, MO, MSI, and LV-EFCMR add incremental prognostic value above traditional outcome markers alone in acute reperfused STEMI.

Abstract:
18 patients presenting with acute carotid territory stroke, secondary to angiographically demonstrated occlusion of the middle cerebral artery (MCA), have been treated within 8 hours of the onset of acute symptoms by local intra-arterial infusion of urokinase or streptokinase. All patients were screened by baseline CT cerebral scan to exclude intracerebral hemorrhage as a cause of the acute stroke. 14 patients demonstrated complete, 2 partial, and 2 no recanalization (reopening) of the previously occluded artery following a 1 to 2 hour infusion of the fibrinolytic agent.10 of the 14 patients displaying complete recanalization had complete neurological recovery or improvement with residual neurological deficits, while the 2 patients who did not display recanalization did not improve clinically. No clinical improvement was observed in the absence of recanalization.Hemorrhagic transformation of cerebral ischemic areas may be classified as hemorrhagic infarction (minimal hemorrhage, no clinical deterioraton) and parenchymatous hemorrhage (mass effect, clinical deterioration). Minor infarction-related hemorrhages without detectable neurological sequelae (hemorrhagic infarctions) were found by CT scan in 4 patients; all displayed complete recanalization; and all hemorrhagic infarctions resolved.This uncontrolled prospective clinical experience suggests that early local infusion of thrombolytic agents in selected patients may be efficacious and safe.

Abstract:
Taurine, an amino acid that is present in high concentrations in the heart, is released from the heart after myocardial damage. There is evidence that the concentration of taurine in whole blood is raised after myocardial infarction (MI), and it has been suggested that blood taurine may be a measure of the degree of infarction. We have obtained serial measurements of blood taurine in patients admitted to a coronary care unit and have compared the results with those obtained for two cardiac enzymes (AST and HBD) and other blood parameters.The patients were divided into two groups: those for whom there was a peak of AST activity (> 40 i.u./l) (Group 1, n = 24) and those for whom AST and HBD was not raised (Group 2, n = 15). For Group 1 patients, mean results were obtained for each of the parameters for the day on which AST peaked (designated Day 0) and for preceeding and subsequent days. For Group 2 a single mean was obtained. Results marked * in the table differ significantly (p < 0.05 or lower) from those for Group 2:It can be seen that blood taurine was significantly raised after MI and followed a pattern similar to the neutrophil count. Furthermore, several positive correlations (r = 0.63-0.79) were obtained between taurine and neutrophil count in both groups, but not between taurine and AST or HBD.In another investigation we measured the amounts of taurine in neutrophils, platelets and plasma from patients with MI (n = 5) and controls (n = 9). We found no differences in the amounts present per neutrophil, per platelet or per ml of plasma.Our data suggest that the increased level of taurine in blood after MI merely reflects the increased number of neutrophils present in blood following the event.

Abstract:
Abstract Diseases of the heart and blood vessels are the number one causes of patient mortality in the United States. Of these conditions, myocardial infarctions, more commonly known as heart attacks, are the most feared of cardiovascular pathologies. The American Heart Association has dedicated billions of dollars over the past four decades to basic science and clinical research to help prevent and treat heart attacks. Detailed assessment of three dimensional stress, strain, and deformation histories is important because it has been noted that reduced transmural strain and left ventricular torsion may be indicative of myocardial infarction resulting from ischemia [1]. Previous studies have been limited to clinical and experimental modalities of study. With the evolution of high speed computers and finite element softwares, detailed and effective biomechanical modeling of complex physiological systems such as the heart have been undertaken. The objective of this study is to utilize finite element analysis to assess local and global deformation and stress patterns in normal vs. imposed conditions of myocardial infarction. Such knowledge obtained a priori could be utilized by cardiothoracic surgeons and cardiologists to improve the efficacy of treatment and treatment options for patients suffering from heart disease.

Abstract:
AMI is a major cause of morbidity and mortality in modern society Conventional treatment has no benefic effect on the size of infarct, alteration of left ventricular (LV) function and mortality. Intravenous (IV) thrombolysis reduces in hospital mortality by 23 % if infused within 3 hours of ischemia, 47 % if within 1 hour. It reduces the size of infarct by 51 % if reperfusion occurs within 1 hour of ischemia, 31 % if between 1 and 2 hours and 13 % if between 2 and 4 hours. The preservation of LV function is of 28 to 42%. These benefic effects, thanks to IV thrombolysis, can be obtained only if reperfusion occurs within 3 or 4 hours of ischemia. Unfortunately, a french prospective study “ENIM 84” estimates that the mean delay between onset of chest pain and arrival at hospital is 10,3 hours.Goals of the study were to show that “at home” thrombolysis: 1) is a feasible and a safe technique, 2) is responsible of a significant saving of time, 3) preserves LV function according to the precocity of treatment.Two groups of patients (pts) are compared : group A : 62 pts had “at home” thrombolysis by a trained medical staff aboard a mobile emergency care unit. Group B : 53 pts had thrombolysis at arrival at CCU. Protocol is simular in both groups : An IV infusion of 1 5 M iu of streptokinase over 45 to 60 min after an IV bolus of 100 mg Hydrocortisone. Criteriae and contra-indications are those usually used for thrombolysis. Radionuclide angiography was performed 4 days and 1 month after AMI to evaluate global and regional ejection fraction (EF). Only 1 hemorrhagic complication (a mild melaena) and 2 reversible ventricular fibrillations were reported. Reperfusion arrythmias were frequent (55 %) but do not need treatment. The number of candidates for thrombolysis is then increased. The saving of time is 73 min. Difference between the 4 days and 1 month EF is not significant in pts with conventional treatment or if reperfusion occurs after 4 hours of ischemia 48 ± 11 % vs 51 ± 13 %.But it is significant if before 4 hours 49 ± 11 % vs 56 ± 12 % and highly significant if before 2 hours 48 ± 12 % vs 59 ± 10 %.

Abstract:
Platelet aggregation has been implicated in the pathogenesis of atherosclerosis and its complications. We studied the prognostic value of the presence of spontaneous platelet aggregation (SPA) after myocardial infarction in 165 patients during a four years follow up period. Shortly after infarction 78 (47%) showed SPA and 87 (53%) showed no SPA. There were no differences in sex, age, infarct size or localisation and subsequent treatment between both groups. Patients in the SPA-positive group remained predominantely positive and patients in de SPA-negative group negative during the entire follow up period.In the SPA-positive group 25(32%) cardiac events (12 × cardiac death, 13× non fatal recurrent infarction) occurred.In the SPA-negative group 13(15%) cardiac events ( 5× cardiac death, 8× non fatal recurrent infarction) occurred (p < 0.01)In conclusion: the presence of spontaneous platelet aggregation after myocardial infarction is associated with a higher risk for fatal or non fatal recurrent myocardial infarction.

Abstract:
Review question / Objective: Whether acupuncture is effective for infarction size on myocardial ischemia rat models. Condition being studied: Myocardial ischemia is a typical pathological condition of coronary heart disease (CHD), which has been a global issue with high incidence and mortality. Myocardial infarction caused by myocardial ischemia leads to cardiac dysfunction, and the size of myocardial infarction also determines the recovery and prognosis of cardiac function. Acupuncture, a long history of traditional Chinese medicine, is widely used to treat symptoms like thoracalgia and palpitation. Many researches based on rat experiments have shown that acupuncture affects infarction size, cardiac function, myocardial enzyme or arrhythmias severity on myocardial ischemia models; nevertheless, few literatures have systematically reviewed these studies, assessing the risk of bias, quality of evidence, validity of results, and summarizing potential mechanisms. A systematic review of animal studies can benefit future experimental designs, promote the conduct and report of basic researches and provide some guidance to translate the achievements of basic researches to clinical application in acupuncture for myocardial ischemia. Therefore, we will conduct this systematic review and meta analysis to evaluate effects of acupuncture on infarction size on myocardial ischemia rat models.
