Filter by:To examine markers of underlying chronic inflammation and infection as potential risk factors for future myocardial infarction (MI), stroke (CVA), and venous thromboembolism (VTE) in plasma samples collected at baseline from healthy participants in the Physicians' Health Study (PHS).
To evaluate the effectiveness of primary prevention of coronary heart disease risk factors by examining data from the National Health Examination Survey (NHES) and the National Health and Nutrition Examination Surveys (NHANES) to determine whether more recent birth cohorts were attaining lower blood pressure and cholesterol levels than earlier birth cohorts.
To compare rates of coronary heart disease (CHD), cancer, total mortality and exercise injuries in 68,000 runners and 68,000 walkers during four years of surveillance
To analyze existing data from the Physicians Health Study (PHS), a randomized primary prevention trial of low-dose aspirin and beta carotene conducted among 22,071 U.S. male physicians, to address questions concerning aspirin and cardiovascular (CV) disease that could not adequately be addressed during the randomized aspirin period.
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.
