Active clinical trials for "Heart Diseases"

To conduct a population-based study of the prevalence of asymptomatic ventricular dysfunction.

To investigate coronary artery calcium (CAC), detected by electron beam computed tomography (EBCT), as a predictor of coronary heart disease (CHD) mortality and morbidity, stroke, and all-cause mortality in a historical cohort epidemiological study.

To develop effective strategies for enhancing adherence to therapeutic interventions designed to improve care for hypertensive minority populations.

To develop and to test a brief telephone intervention following clinic treatment for smoking cessation.

To conduct focused studies of lipoprotein physiology and pathophysiology in genetically characterized patients with the objectives of understanding disease mechanisms, developing better treatments, and identifying and preventing early vascular disease.

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 conduct a randomized controlled smoking prevention trial to evaluate quality of implementation and effectiveness, as a function of provider type (school teacher vs. nurse) and training (mediated vs. interactive).

To examine the mechanism through which social support affects morbidity and mortality from coronary heart disease.

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 investigate the relationship between coronary heart disease risk factors and coronary artery calcification in middle age adults from the Muscatine Study. From 1992 through 1995, ultrafast computed tomography was used to measure coronary artery calcification. The study has been extended through January, 2001 in order to examine the role of electron beam computed tomography in detecting the presence and quantity of coronary artery calcification, a marker of the atherosclerotic process.
