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.

Medical information is increasingly processed electronically. This study will describe the similarities and differences in the data recorded by different databases of electronic healthcare database. These will include the General Practice Research Database (GPRD) and the Myocardial Ischaemia National Audit Project (MINAP) and hospital episode statistics (HES).

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.

This study is being done to learn more about platelet reactivity (how well the small cells in the bloodstream work) in people who undergo Percutaneous coronary intervention (PCI) for stable and unstable (acute myocardial infarction) indications. Stable means you have not demonstrated any acute injury to your heart prior to your PCI; unstable means you have demonstrated some acute injury to your heart prior to your PCI. The investigators intend to determine if there is a change in platelet reactivity from the time of PCI to 30days post-PCI and does this change differ depending upon the conduction in which you present for PCI. This is going to be done with a variety of platelet reactivity assays.

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.

The Sweetheart register (Risk management of Diabetics with acute myocardial infarction) documents both the prevalence of pathologic glucose metabolism in consecutive high-risk patients with STEMI and NSTEMI in daily hospital routine as well as the anti-diabetic acute and long-term therapy. Furthermore the register will provide data about the implementation of new guidelines for the interventional and adjuvant medical therapy of STEMI and NSTEMI.

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.

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.

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

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
