Active clinical trials for "Heart Diseases"

To determine the factors associated with progression of sub-clinical atherosclerosis and to evaluate the associations between the progression of sub-clinical atherosclerosis and the development of clinically manifest atherosclerosis.

To monitor trends in congestive heart failure in Olmsted County, Minnesota.

To evaluate whether genetic variation in selected candidate genes is associated with risk of sudden cardiac death in the general population.

To test the hypothesis that breast arterial calcification (BAC) seen on mammograms can identify women with an increased risk of coronary artery disease (CAD).

To continue surveillance of cardiovascular disease risk factors in the seven-county area of Minneapolis-St. Paul.

To determine the predictors of perioperative cardiac morbidity and mortality in patients at high risk who underwent major noncardiac surgery with general anesthesia.

To develop a prototype questionnaire for the detection of angina pectoris in Blacks.

To detect by Doppler echocardiography the incidence of cardiac abnormalities in HIV-positive patients in a prospective, longitudinal study.

To explain the extremely low cardiovascular mortality among Physicians' Health Study (PHS) participants by ascertaining all cardiovascular and total deaths among the 90,457 physicians who returned enrollment forms but were not randomized into the study. Also, to compare the mortality experience of randomized physicians with various subgroups of non-participants.

To examine the natural history of mortality due to coronary heart disease in post-myocardial infarction patients from the Beta-Blocker Heart Attack Trial (BHAT) and the Aspirin Myocardial Infarction Study (AMIS).
