Active clinical trials for "Myocardial Infarction"

This study is performed to observe the incidence of major cardiovascular events in Korean patients with AMI after giving pitavastatin 2mg and 4mg longer than 1 year.

The purpose of this study is to determine if heredity influences the risk of life-threatening heart rhythms (ventricular tachycardia and ventricular fibrillation) after heart attack (myocardial infarction).

This study uses the PharMetrics and MarketScan US health care insurance claims database to estimate relative risks for non-fatal venous thromboembolism (including cerebral venous sinus thrombosis), ischemic stroke, and acute myocardial infarction (heart attack), in current users of ORTHO EVRA (norelgestromin and ethinyl estradiol contraceptive patch) compared to current users of oral levonorgestrel-containing oral contraceptives with 30 micrograms ethinyl estradiol, with special attention to duration of use.

The Copenhagen City Heart Study is an ongoing cardiovascular population study initiated in 1976 which has examined approximately 25,000 individuals from the general population. The initial sample has been re-invited up to four times and supplemented by younger individuals. The study includes questionnaires, clinical assessment and biomarkers. The population have been followed in a number of outcome registries and more than 900 scientific papers have been published.

The purpose of this study is to examine the incidence of acute myocardial infarction (MI) occurring after an influenza-like illness using linked primary care and disease registry databases.

Practice in management of myocardial ischemia and infarction has changed significantly over the past 20 years, both in terms of immediate management and secondary prevention. The aim of this observational study is to utilize the established record linkage data available in Tayside to investigate the trends in survivors of myocardial infarction in Tayside since 1994.

Diabetes mellitus is a major risk factor for the development of ischemic heart disease, and patients with diabetes mellitus have a worse outcome following an acute myocardial infarction than non-diabetic patients. Furthermore, abnormal glucose metabolism below the diagnostic threshold of diabetes mellitus is also associated with increased risk of death compared to patients with a normal glucose metabolism. The frequency of abnormal glucose metabolism in acute myocardial infarction is high, and approximately 70% of myocardial infarction patients have diabetes mellitus, newly diagnosed diabetes mellitus or impaired glucose tolerance, leaving only 30% with normal glucose metabolism. The increased mortality among patients with acute myocardial infarction and abnormal glucose metabolism seems mainly related to a higher occurrence of congestive heart failure, suggesting that an abnormal glucose metabolism may play an important role among others in endothelial dysfunction, infarct healing and overall left ventricle function. This raises the question, whether patients with acute myocardial infarction and abnormal glucose metabolism have increased frequency of micro- or macrovascular disease or both. Coronary flow velocity reserve reflects the patency of the epicardial coronary artery in combination with vasodilator capacity of the microcirculation and may therefore offer a tool for assessment of macro- and microcirculation. This study will focus on the relation between coronary flow velocity reserve estimated by transthoracal Doppler echocardiography and mortality, risk for heart failure and left ventricle function after acute myocardial infarction stratified according to glycometabolic state

This is a cross-sectional study of post myocardial infarction patients which is designed to determine the prevalence of left ventricular thrombi (blood clots) using non-contrast echocardiography and to compare this with the prevalence of left ventricular thrombi using contrast echocardiography. Secondary aims of this study are (1) to identify clinical and imaging correlates of left ventricular thrombi, and (2) to compare quantitative measurements of left ventricular chamber size, function, and myocardial mass using contrast and non-contrast echocardiography.

The main objective of this case-referent study is to assess the impact of statins usage on the risk of having a first myocardial infarction (MI) in a real life situation in France

TEG is an established technique to assess the quality of clot formation' used mainly in surgery and obstetrics to determine possible bleeding diathesis. Recently it became to be used in cardiology, where it can be a valuable tool to assess a response to antiplatelet therapy and its association with the outcome. However, there is a few data about use of TEG in STEMI patients undergoing PCI. Our study is designed to assess by TEG the platelet's response to clopidogrel treatment during acute STEMI in patients undergoing primary PCI and the correlation of this response with the long term outcome, and ability to dose adjustment according to a specific measurement by TEG in order to prevent future MACE.
