Active clinical trials for "Heart Diseases"

To define pediatric sex-specific blood pressure percentiles that were a function of both age and height. Also, to define the precise age at which blood pressure distributions for different racial groups diverged.

To seek predictors of mortality, hospitalization, and dialysis using data from a hypertensive population which began treatment in 1974.

A detailed review was made of data pertinent to the occurrence of chronic Chagas disease in the United States.

To study calcium metabolism and the renin-angiotensin system in hypertensive and normal pregnancy.

To perform extensive analyses of data from the Dietary Intervention Study of Hypertension (DISH)..

To elucidate the interrelationship of level of cardiovascular disease knowledge and subsequent clinical health status by merging population-based cardiovascular disease risk factor survey data with patient-level hospital data. The overall goal was to assess outcomes in the positive/negative association between level of cardiovascular disease knowledge and incidence and relative degree of morbidity among a cohort with and without major cardiovascular disease risk factors.

To continue the work of the Collaborative Studies Coordinating Center (CSCC) on international studies in cardiopulmonary disease epidemiology. The work was being performed under bilateral agreements that the NHLBI had entered into with Russia, The People's Republic of China and Pakistan. The contract provided nutritional, epidemiologic and biostatistical services in support of these studies.

To continue a prospective study of the ability of ambulatory blood pressure to predict cardiovascular morbidity in patients with mild hypertension.

To use a new statistical method, the Logical Analysis of Data (LAD), to predict cardiac surgery risk.

To localize and identify new genes related to variation in blood pressure (BP) responses to a low dietary sodium intake, a high dietary sodium intake, oral potassium supplementation, and the cold pressor test.
