Filter by:To determine if estrogen therapy in postmenopausal women with unstable angina reduces the incidence of ischemic episodes.
To determine whether combined therapy with the lipid lowering agents colestipol hydrochloride plus niacin would produce significant change in coronary, carotid, and femoral artery atherosclerosis and coronary bypass graft lesions as determined by angiography. Also, to determine possible correlations between lesion changes and plasma lipid and lipoprotein cholesterol levels and to explore interrelationships of atherosclerosis change in femoral, coronary, and carotid arteries.
To determine the effect in men and postmenopausal women with elevated LDL-cholesterol and low HDL-cholesterol of an exercise regimen with or without the National Cholesterol Education Program (NCEP) Step Two diet compared to usual care control group on HDL- and LDL-cholesterol.
To determine whether lowering of cholesterol with cholestyramine in a population with Type II hyperlipidemia led to a decreased rate of progression (a regression of coronary artery disease) as demonstrated by death, myocardial infarction, or progression of disease on angiography.
To determine if dual chamber rate-modulated pacing (DDDR) in patients with sick sinus syndrome is superior to single chamber pacing (VVIR) with respect to subsequent frequency of adverse clinical events such as stroke, quality of life and function, and cost effectiveness.
To determine if addition of a beta-blocker to standard therapy in Class III and Class IV heart failure patients reduced total mortality.
To determine the effects, in postmenopausal women, of hormone replacement therapy on progression/regression of coronary heart disease, as measured by quantitative angiography.
To determine whether the addition of angiotensin converting enzyme (ACE) inhibitor to standard therapy in patients with known coronary artery disease and preserved left ventricular function will prevent cardiovascular mortality and reduce the risk of myocardial infarction.
To evaluate the effect of psychosocial intervention on mortality and reinfarction in coronary heart disease patients at high psychosocial risk.
To compare two standard treatment strategies for atrial fibrillation: ventricular rate control and anticoagulation vs. rhythm control and anticoagulation.
