Active clinical trials for "Heart Diseases"

To examine the vagal, vascular sympathetic, and mechno-structural components of baroreflex regulation in coronary artery disease (CAD) patients and healthy age-matched controls during rest and acute laboratory stress.

To identify genes causing hypertensive end-stage renal disease (H-ESRD) in high risk African-American populations

To conduct a multicenter prevalence survey for characterizing pathologically the extent of atherosclerosis in the aortas and coronary arteries of young persons dying from accidental causes, suicide, or homicide.

To investigate the differential diagnosis and longitudinal course of medical outpatients complaining of palpitations. Also, to further examine the process of cardiac perception, the psychological factors which influence it, and the accurate awareness of cardiac arrhythmias.

To determine inflammation markers over time in cardiovascular disease. To test the hypothesis that measures of coagulation and fibrinolysis correlate with the incidence of coronary heart disease (CHD) and other thrombosis related disorders, and to help identify those individuals at greatest risk, using the Cardiovascular Health Study (CHS) and Honolulu Heart Program (HHP) populations. These two genetically distinct populations had different event rates for CHD, and offered a unique opportunity to test associations that were uncovered by comparing results across populations.

To develop a comprehensive database publication (databook) utilizing available published and unpublished data on the prevalence of hypertension and its treatment and control in selected minority populations in the United States -- Hispanic, Asian and American Indian.

Originally from 1991 to 1991, to test the hypothesis that differences in hypertension prevalence in Nigerian workers were primarily related to differences in socioeconomic status (SES). At renewal in 1996, to determine the importance of weight gain and weight-related factors in blood pressure.

To study the personality and environmental factors that may determine the short-term and long-term sequelae of coronary artery bypass surgery (CABS).

To relate distribution of adipose tissue measured by a then new imaging technique, Magnetic Resonance Imaging (MRI) to extracranial carotid atherosclerosis, cardiovascular disease risk factors, and to more conventional measures of fat distribution such as body mass index (BMI) and waist/hip ratio. The primary hypothesis was that patients with extracranial carotid atherosclerosis (cases) had more intra-abdominal fat and a higher ratio of intra-abdominal fat to total or subcutaneous fat than age-sex-race matched controls.

To prospectively examine changes in lipids, lipoproteins, and blood pressure among 295 young adults who had been followed for sixteen years in the Beaver County Lipid Study. The Beaver County Lipid Study tracked the cholesterol values of 295 children, ages 11 to 14 at baseline.
