Filter by:To establish the incidence, clinical spectrum, and natural history of cardiac dysautonomia as defined by heart rate spectral analysis in both HIV infected and noninfected children and to evaluate the value of heart rate spectral analysis for predicting dysrhythmias and sudden death in infants and children born to HIV infected mothers.
To conduct a prospective, longitudinal, analysis of the psychophysiological effects of chronic exposure to environmental stress. The study took advantage of a unique, naturally occurring experiment caused by the relocation of a major international airport.
To determine the cost-effectiveness of alternative strategies for cholesterol reduction.
Using subjects from the Rochester Family Heart Study (RFHS), to characterize predictors of coronary artery calcification (CAC), a potent marker of atherosclerosis, among individuals from the general population.
To relate distribution of adipose tissue measured by a then new imaging technique, Magnetic Resonance Imaging (MRI) to extracranial carotid atherosclerosis, cardiovascular disease risk factors, and to more conventional measures of fat distribution such as body mass index (BMI) and waist/hip ratio. The primary hypothesis was that patients with extracranial carotid atherosclerosis (cases) had more intra-abdominal fat and a higher ratio of intra-abdominal fat to total or subcutaneous fat than age-sex-race matched controls.
To examine the associations between diet, nutrition and coronary heart disease (CHD) incidence over seven years using the Cycle V Framingham Offspring/Spouse examination ; to examine the cross-sectional associations between dietary variables and major cardiovascular disease risk factors, to examine changes in dietary behaviors and their determinants over seven years; and to characterize the influences of dietary behavior changes on risk factor status between 1984-88 and 1991-94.
To understand the mechanism(s) underlying sodium-dependent blood pressure control, and to determine the consequences thereof.
To conduct a genetic epidemiologic study of the coronary heart disease (CHD) risk factors of blood lipids and obesity in Black and white girls who participated in the NHLBI-supported National Growth and Health Study (NGHS). The study was ancillary to NGHS.
To determine prospectively the extent to which structural and functional aspects of social support influences 'hard' cardiac events such as death and non-fatal myocardial infarction in patients with coronary artery disease (CAD) and to identify the behavioral and biological mediators of these influences.
To examine the mechanism through which social support affects morbidity and mortality from coronary heart disease.
