Active clinical trials for "Heart Diseases"

To examine associations between various dietary elements and the risk of coronary heart disease and stroke.

To evaluate the role of known genes involved in lipid metabolism on serum lipid and apolipoprotein levels in Samoans residing in American and Western Samoa, who were exposed to the biobehavioral changes of modernization.

To examine the separate and interactive effects of hostility, depressive symptomatology and socioeconomic status (SES) in predicting coronary heart disease risk.

To conduct gene mapping studies for quantitative traits.

To determine the effects of behavioral stress and reproductive hormones on coronary heart disease (CHD) risk.

To investigate the prevalence and incidence rates of cardiovascular disease morbidity and mortality in people with Type 1 diabetes of long duration.

To determine if risk factors measured in childhood can predict the development of atherosclerotic coronary and carotid artery disease in adulthood.

To evaluate children undergoing catheter ablation at pediatric centers in North America in order to provide information on the incidence rate of serious cardiac damage as a result of ablation, the incidence rate and time course of recurrence after initially successful ablation, and the incidence rate of proarrhythmia following ablation.

To determine mechanisms of low levels of apolipoprotein B.

To investigate the genetics and epidemiology of fasting and postprandial lipid, lipoprotein, and apolipoprotein levels.
