Active clinical trials for "Heart Diseases"

To assess in four large Chicago population cohorts whether young adult and middle-aged risk factor status has an impact not only on average annual Medicare costs, but also on cumulative and lifetime Medicare costs, to ages 70, 75, 80, >80, including to death, and during the last one to two years of life.

To document cardiovascular disease and cardiovascular disease risk factors among 1,200 Native Alaskans who are members of approximately 40 families.

To determine the genetics and epidemiology of different types of early familial coronary disease. Accurate markers of major gene syndromes for early coronary disease were identified using a genetic segregation and linkage study of lipids, lipoproteins, apolipoproteins, and DNA probes in 36 large Utah pedigrees.

To estimate probabilities of death by cause for a representative United States population, according to age, sex, race, occupation, industry, income, education, residence, country of birth, calendar year, and a number of other demographic and epidemiologic factors. The representative population is derived from selected Bureau of the Census files and is matched to the National Death Index maintained by the National Center for Health Statistics. The Bureau of the Census provides the data processing, coding and management necessary to complete this objective.

To assess the association of immunogenetic factors with onset of coronary heart disease and the interrelationship of these factors with standard coronary heart disease risk factors.

To determine whether the degree of carotid artery atherosclerosis, as measured by B-mode ultrasound, predicts the development of myocardial infarction, stroke, and all-cause mortality in patients with angiographically defined coronary status. Also, to quantify the rate of progression of carotid artery disease and to evaluate the risk factors associated with progression of carotid atherosclerosis.

To study the relationship between diabetes and various macro- and microvascular complications in Oklahoma Indians.

To establish a registry in order to collect and analyze baseline and outcome data on patients with severe valvular stenosis treated with balloon valvuloplasty.

To evaluate possible early neurogenic influence in essential hypertension by monitoring heart growth in adolescents over a two year interval.

To determine if hypertensives and normotensives of similar ages had, on average, different ratios of 24-hour to overnight excretion of sodium, potassium, and water. Also, to determine the number of 24-hour collections needed to characterize individuals with respect to the ratios of 24-hour to overnight excretion and to determine if the ratios of 24-hour to overnight excretion vary by age and other factors related to blood pressure.
