The study recruited 364 siblings of individuals with early coronary disease. Eligible subjects were randomized to community-based care (CBC) or enhanced primary care (EPC) with a community health site neighborhood health worker/nurse for 1 year follow up. Intervention participants were stratified based on results of treadmill testing to either more or less aggressive management of their lipids according to National Cholesterol Education Program guidelines. All positive participants on the exercise stress test were directly referred to their physicians. Diabetics were referred to their primary physician for treatment. Intervention in the intervention group was carried out on traditional coronary heart disease (CHD) risk factors including diet, physical activity, blood pressure, LDL cholesterol, and cigarette smoking. The intervention built on a prior sibling study in Blacks and whites.
