The trial has been extended through November 2002 to complete the minimum ten-year followup on all BARI patients, determine the relative efficacy of PTCA versus CABG in subgroups of women, Blacks, diabetics, and elderly, and assess the public health impact of BARI. In the followup, all currently enrolled patients will have annual telephone interviews. At ten years, the electrocardiogram will be obtained on all patients and blood lipid levels will be performed on randomized patients only. All hospitalizations that occurred since the last contact will be identified on the annual telephone contact. Angina will be assessed for the preceding six weeks. At each patient contact, patients will be instructed in behavior modification in the areas of smoking cessation, exercise, and diet. Angiographic studies will also be conducted as part of the ten-year follow-up. The four centers which participated in the first phase of these BARI activities will again conduct the angiograms. Patients will consist of the established cohort drawn from the randomized participants who completed one and five year angiograms.
