Among patients undergoing elective primary coronary artery bypass graft (CABG), the principal objective of this randomized trial was to compare the efficacy of two strategies of intra-operative hemodynamic management during cardiopulmonary bypass in preventing peri-operative cardiac, cognitive and neurologic morbidity and mortality, and post-operative deterioration in patients' quality of life as measured by the SF-36.
To provide a comprehensive description of smoking beliefs and behavior among rural Blacks, and to test the effectiveness of smoking cessation strategies delivered through Black churches.
To test the hypothesis that the aggressive treatment of plasma LDL and oxidized LDL will result in improvements in the activity of ischemia in patients with coronary artery disease and will reverse characteristic cell/vessel wall dysfunctions in the arteries of these patients.
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 conduct a multicenter prevalence survey for characterizing pathologically the extent of atherosclerosis in the aortas and coronary arteries of young persons dying from accidental causes, suicide, or homicide.
To foster collaboration between the World Health Organization MONICA Project and the NHLBI Study of Atherosclerosis Risk in Communities (ARIC). To ensure that valid comparisons could made between findings in MONICA and ARIC by supporting activities to standardize coding, classification, and analysis of coronary and stroke events, risk factors, and medical care according to MONICA protocol.
To evaluate the long-term efficacy of percutaneous transluminal coronary angioplasty (PTCA) and alternative angioplasty devices in patients with coronary heart disease. There are four registries. The first registry followed 3,079 patients who received PTCA between 1977 and 1982. The second registry followed 1,500 patients from the first registry for a minimum of five years and followed 2,000 newly entered patients who received PTCA in 1985 and 1986 so that the second cohort would also be followed for five years. The third registry, the New Approaches to Coronary Intervention (NACI), followed approximately 4,424 patients between November 1990 and February 1997. The dynamic evaluation study will follow a total of 6,000 procedures.
To investigate the relative contributions of high density lipoprotein-C (HDL-C) subspecies to risk for coronary heart disease (CHD) in two distinct existing populations (samples from the VA-HIT study and the Framingham Offspring Study [FOS]) as well as the response of these subfractions to gemfibrozil treatment.
This study will examine the health-related quality of life in patients being treated for chronic heart disease. Patients 18 years or older with chronic ischemic heart disease and left ventricular dysfunction enrolled in protocols in the National Heart Lung and Blood Institute's Cardiology Branch may participate in this study. Participants will complete five questionnaires at 3 separate times during the study-once during hospitalization at the NIH Clinical Center and again at home 6 months and 1 year later. The questionnaires, described below, require a total of about 30 minutes to complete. 1. Demographic Information Sheet -General information such as age, marital status, employment, education, and history of cardiac medical procedures. 2.
