Active clinical trials for "Myocardial Infarction"

The Dallas Heart Study (DHS-1) is a large, multi-ethnic, population-based epidemiological study designed to identify determinants of atherosclerotic heart disease (ASHD) in a representative United States (US) urban environment. This study completed enrollment in 2003. Our objective is to pinpoint factors contributing to progression: from health to ASHD risk; from ASHD risk to subclinical ASHD; and from subclinical to clinical ASHD. Identification of the critical factors in these transitions will enable targeted implementation of appropriate therapy to interdict before clinical ASHD develops.

Magnetic resonance imaging (MRI) and echocardiography are two imaging methods that are used to obtain pictures of the heart and assess heart function. This study will evaluate a new, four-dimensional echocardiography approach of obtaining heart images to determine if it is as effective at evaluating heart function as MRI.

compare measurements of left ventricular volumes and LVEF obtained by 2DE, 3DE, and CMR after a ST elevation myocardial infarction (STEMI) complicated by systolic left ventricular dysfunction

Reperfusion delay in STEMI has been shown to be excessive in our community. In order to improve delay a fast track (direct transfer in catheterization laboratory) has been implemented. The present study aims at evaluating the benefits of this procedure.

The purpose of this study is to describe the efficacy and safety of prehospital administration of bivalirudin, as a substitute for heparin, in patients with acute myocardial infarction redirected for primary angioplasty bypassing local hospitals, immediately after the diagnosis is confirmed via tele-transmission of a 12-lead electrocardiogram.

To examine the association of subclinical hypothyroidism and risk of myocardial infarction and stroke in a large prospective cohort of post-menopausal women.

To examine the relationship between genetic and dietary factors that modify the risk of coronary heart disease (CHD).

To evaluate very low density lipoprotein (VLDL) and low density lipoprotein (LDL) particle types as predictors of initial coronary events.

To evaluate the relationship of baseline toenail chromium concentrations to weight loss, as well as the interaction between heavy metals and the beneficial effects of weight loss.

To determine the incidence of type II diabetes and cardiovascular disease among Mexican-American and non-Hispanic whites in a 15 to 24 year follow-up of the San Antonio Heart Study 1 participants. Also, to perform a 15 to 24 year mortality follow-up of the cohort and to examine the "Hispanic paradox".
