Filter by:To determine the role of the prorenin-renin-angiotensin-aldosterone system (RAAS) in normal and hypertensive pregnancy.
To determine if low dietary calcium intake and disturbances in maternal calcium metabolism were associated with increases in blood pressure in late pregnancy.
To determine the incidence of type II diabetes and cardiovascular disease among Mexican-American and non-Hispanic whites in a 15 to 24 year follow-up of the San Antonio Heart Study 1 participants. Also, to perform a 15 to 24 year mortality follow-up of the cohort and to examine the "Hispanic paradox".
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.
To perform genetic studies of low density lipoprotein (LDL) subclasses in 160 families in whom the probands had metabolically defined hypercholesterolemia.
To validate two models which categorized patients with syncope into high and low risk for either sudden death or diagnostic arrhythmias based on data available from the initial history, physical examination, and electrocardiogram.
To evaluate possible early neurogenic influence in essential hypertension by monitoring heart growth in adolescents over a two year interval.
To determine the natural history of coronary heart disease in the biethnic community of Corpus Christi, Texas.
To determine the predictors of perioperative cardiac morbidity and mortality in patients at high risk who underwent major noncardiac surgery with general anesthesia.
To examine time trends in the incidence rates of acute myocardial infarction and out-of-hospital coronary heart disease deaths as well as changes in the in-hospital and long-term case-fatality rates of acute myocardial infarction in the Worcester, Massachusetts Standard Metropolitan Statistical Area (SMSA).
