Active clinical trials for "Heart Diseases"

To determine the role of environmental stressors in the development of hypertension in Black and white school-age children from hypertensive families.

To examine the relationships of obesity and fat patterning with morbidity and mortality in Black Americans.

To test the hypothesis that the incidence of coronary heart disease and cardiovascular mortality could be accurately predicted by the presence of coronary calcific deposits detected by cardiac fluoroscopy.

To examine the relationships among psychosocial factors and carotid atherosclerosis, myocardial ischemia, arrhythmias, and thrombosis.

To identify risk factors for idiopathic dilated cardiomyopathy and to examine prognostic factors over a follow-up period of two to three years.

To examine the relationship of obesity and body fat distribution to lipoprotein concentrations in members of the Strong Heart Study.

To elucidate dietary factors that elevate risk for cardiovascular disease (CVD) in conjunction with insulin resistance.

To understand the mechanism(s) underlying sodium-dependent blood pressure control, and to determine the consequences thereof.

Using subjects from the Rochester Family Heart Study (RFHS), to characterize predictors of coronary artery calcification (CAC), a potent marker of atherosclerosis, among individuals from the general population.

To establish the incidence, clinical spectrum, and natural history of cardiac dysautonomia as defined by heart rate spectral analysis in both HIV infected and noninfected children and to evaluate the value of heart rate spectral analysis for predicting dysrhythmias and sudden death in infants and children born to HIV infected mothers.
