Active clinical trials for "Myocardial Infarction"

the objective of the Israeli MGurad Registry is to evaluate the 'Real World' Clinical Performance of the InspireMD MGuard Coronary Stent System

Letigen® was a combination drug containing ephedrine, an adrenergic agonist with lipolytic and appetite-inhibiting properties. The drug was used as adjuvant treatment of obesity from 1990 and up to 2002 when it was withdrawn from the market by the manufacturer. The basis for this was a number of spontaneous reports about patients that died during treatment with Letigen®. The causal relation has never been addressed. There are only sparse data from randomised studies and the above-mentioned reports are not conclusive. We propose a controlled study based on data from Statistics Denmark that hold a complete copy of the Prescription Register of the Danish Medicines Agency and the Danish Hospital Discharge Register. The aim of the study would be to determine whether there is an excess frequency of deaths and serious cardiovascular events that can not be explained by particular characteristics of users of the drug. A well-known problem in such observational studies is a fundamental incomparability between users and non-users of drugs. In the present setting, it should be expected that use of Letigen® is associated with high BMI, smoking, alcohol abuse, type-2 diabetes, mild hypertension, low physical activity and other indicators of unhealthy lifestyle. Thus, an uncritical comparison between users and non-users of Letigen® regarding serious cardiovascular events will probably show an excess frequency that can not necessarily be attributed to the drug. This problem can be addressed by a special epidemiological technique - the case-crossover design - which is particularly robust to such comparability problems. In brief, only cases should be included. Controls are the same persons at an earlier time, , where the case-defining disease has not yet developed. The exposure of cases will be compared with the exposure of the same persons' case history. To account for the effect of chronic exposure, we also perform, as a secondary analysis, a conventional case-control study nested within the cohort of Letigen users, and employing a risk-set sampling technique.

Our study is to investigate the effect of N-3 Fatty Acids for the prevention of atrial fibrillation in patients with acute heart failure or acute myocardial infarction

The purpose of the PACE-MI (OBTAIN) registry is: Analyze beta-blocker dose response effect on outcome over two years Explore gender and minority differences in beta-blocker utilization and outcomes. In patients with Myocardial Infarction (MI) discharged from the hospital, beta-blocker dose will be predictive of survival. Exploratory analyses: Gender and racial effects-gender and race are, similarly, hypothesized to be predictive of post-MI survival. The existence of interactions between gender and beta-blocker effect as well as race and beta-blocker effect will also be evaluated.

The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.

To investigate the association of selected genetic markers of inflammation and endothelial activation with the occurrence of non-fatal acute myocardial infarction (MI).

To explore whether reduced systemic pain perception in response to painful stimuli and personality pain related variables characterizes silent MI patients.

The VIAMI-trial investigates the effects of balloon angioplasty with stenting of the infarct-vessel in the early phase after acute myocardial infarction. The study concerns patients who have residual viable tissue in the infarct-area after being treated with thrombolysis. It is postulated that only patients with remaining viable tissue are at high-risk for recurrent infarction or anginal attacks and that stenting of the infarct-vessel will reduce this risk considerably.

To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.

To determine if silent myocardial ischemia was associated with an increased risk of cardiac mortality and morbidity during a one to three year follow-up in patients with coronary heart disease.
