Active clinical trials for "Infarction"

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.

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.

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 test the hypothesis that low levels of free protein S, a natural anticoagulant protein in plasma, were associated with an increased incidence of myocardial infarction in middle aged men and women.

To determine prospectively the extent to which structural and functional aspects of social support influences 'hard' cardiac events such as death and non-fatal myocardial infarction in patients with coronary artery disease (CAD) and to identify the behavioral and biological mediators of these influences.

To evaluate the safety of calcium-channel blockers in the secondary prevention of myocardial infarction in women.
