Active clinical trials for "Myocardial Ischemia"

In the first study, to identify children at high and low risk for cardiovascular disease and study their nutritional and physical activity behaviors as they relate to cardiovascular disease. In the second study, to make yearly assessments over a four year period of diet and physical activity among children and their parents. The initial effort redefined and retested methods to collect data on dietary intake and activity levels of young children.

To determine if silent myocardial ischemia was associated with an increased risk of cardiac mortality and morbidity during a one to three year follow-up in patients with coronary heart disease.

To examine factors affecting heart rate variability (HRV) and the role of HRV in heart disease. Specifically, to examine the role of HRV: as a predictor of fatal and nonfatal ischemic heart disease over a six year follow-up of the Atherosclerosis Risk in Communities (ARIC) population based, bi-ethnic cohort; on the six year progression of carotid atherosclerosis measured by B-mode ultrasound; and on the incidence of hypertension. Also, to study the effect of elevated fasting insulin, glucose, diabetes mellitus, and other metabolic abnormalities on changes in HRV over nine years of follow-up.

To evaluate subclinical atherosclerotic disease in menopausal women.

To test the effectiveness of a community site neighborhood health worker/nurse (NHW/N) case management strategy for coronary heart disease risk reduction compared with usual care in apparently healthy African American siblings of persons with documented premature coronary heart disease.

To quantify the role of dietary factors in the etiology of coronary heart disease by pooling data from 10 major prospective studies on diet and coronary heart disease.

To examine the effect on health and disease of the work environment, psychological workload, control over work pacing and content, opportunity for use of skills, social support at work; the moderating effect on these relationships of social supports; and, the interaction between these psychosocial factors and other established risk factors in the etiology of chronic disease.

To continue analysis of data from a longitudinal study of 246 urban Black preschool children and their families in order to identify the long-term effects of social and environmental influences on nutrition and activity and the consequences of these influences for the children's cardiovascular disease (CVD) risk status.

To evaluate the cost-effectiveness of cholesterol-lowering strategies in the United States population. The study used the Coronary Heart Disease (CHD) Policy Model, a state-transition computer simulation model used to obtain forecasts of the public health impact and economic cost of CHD in the United States population.

This prospective, observational study evaluates the accuracy of stress testing with the MyoStrain SENC CMR Imaging System to detect myocardial ischemia and viability in patients with suspected coronary artery disease using low levels of stress.
