Filter by:To determine whether a dietary supplement of n-3 polyunsaturated fatty acids (PUFAs) derived from fish oil would decrease the restenosis rate in patients undergoing percutaneous transluminal coronary angioplasty (PTCA).
The Thrombolysis in Myocardial Ischemia Trial (TIMI III) focused on unstable angina and non-Q-wave myocardial infarction. The trial was designed to determine by coronary arteriography the incidence of coronary thrombi in these conditions and the response of these thrombi to tissue-type plasminogen activator (t-PA) in TIMI IIIA and the effects of thrombolytic therapy and of an early invasive strategy on clinical outcome in TIMI IIIB. There was also a registry with two components. A roster enumerated all patients with unstable angina or non-Q-wave myocardial infarction enrolled at cooperating hospitals. From the roster, a study population of 1,893 subjects was selected and followed prospectively for the year to determine incidence of death or myocardial infarction.
To assess long-term effects of a strict lifestyle change program on lipids, blood pressure, myocardial perfusion, and coronary atherosclerosis.
To compare the influence of two surgical anesthetic techniques, hypothermia with circulatory arrest or hypothermia with low-flow bypass perfusion, on neurologic functioning in infants undergoing heart surgery.
To determine whether warfarin or lovastatin alone or in combination retarded the progression of atherosclerotic plaques in the carotid arteries of high risk individuals with asymptomatic carotid stenosis. Also, to determine if a full scale trial was feasible.
To determine the practicality, benefit, and safety of paramedic administration of thrombolytic therapy for acute myocardial infarction. The feasibility of paramedics correctly identifying candidates for thrombolytic therapy following myocardial infarction was assessed in Phase I. In Phase II, pre-hospital thrombolytic therapy was compared with in-hospital thrombolytic therapy.
To assess the effectiveness of school-based risk reduction interventions involving three components: environmental changes related to food consumption, physical activity, and smoking policy in the school; classroom curriculum; and family and home-based education.
To assess the effects of various postmenopausal estrogen replacement therapies on selected cardiovascular risk factors, including high density lipoprotein cholesterol, systolic blood pressure, fibrinogen, and insulin and on osteoporosis risk factors. Conducted in collaboration with the National Institute of Child Health and Human Development, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, The National Institute of Diabetes and Digestive and Kidney Diseases, and the National Institute on Aging. The extended follow-up is for 3 years focusing on endometrium and breast evaluation.
To compare the efficacy of coronary artery bypass graft (CABG) surgery with percutaneous transluminal coronary angioplasty (PTCA) in patients with multiple vessel coronary heart disease.
To compare the efficacy of amiodarone to conventional anti-arrhythmic therapy in individuals who had survived one episode of out-of-hospital cardiac arrest.
