Filter by:To conduct a pooled analysis of NHANES I/II data on race, gender, and coronary heart disease.
To identify and measure DNA sequence variation in 13 genes that play a central role in key physiological functions involved in the development of cardiovascular disease, that is, genes involved in lipid metabolism, carbohydrate metabolism, and blood pressure regulation.
To identify the role of salt-sensitivity of blood pressure in the pathogenesis of hypertension.
To examine the impact of an interaction between common genetic susceptibility markers and environmental exposures on risk for early onset myocardial infarction in cases with myocardial infarction and matching controls.
To describe the distribution of homocysteine and prevalence of hyperhomocysteinemia with emphasis on race, sex and age. To determine the extent to which hyperhomocysteinemia is associated with status of folate and vitamin B12. Finally, to describe the relationships between prevalence of hyperhomocysteinemia and prevalence of cardiovascular disease and assess the importance of this risk factor as a cause of vascular disease among US adults. The study was renewed for one year to investigate normal homocysteine concentrations among children and to identify nutritional and non-nutritional determinants of total homocysteine concentrations in children.
To test the hypotheses that the risk of myocardial infarction and/or stroke is associated with elevated plasma levels of homocysteine, and low plasma levels of folate, vitamins B12 and B6.
To determine the nature, extent and molecular mechanisms responsible for impaired fibrinolysis in White, Black, Hispanic and American Indian populations with respect to the presence or absence of diabetes. The overall objective is to determine whether impairments of fibrinolysis underlie subclinical and clinical vascular disease in diabetes in specific populations with and without accelerated microvascular disease.
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 better understand the excess cardiovascular disease associated with diabetes mellitus.
To elucidate the changes in body size, composition, and configuration occurring in adolescence, because these are important precursors of change in blood pressure and blood lipids.
