Occlusion rate of distal anastomoses was 11 % in the aspirin plus dipyridamole group, 15% in the aspirin group and 13% in the oral anticoagulation group. Clinical events occurred in 20.3% of patients receiving aspirin plus dipyridamole, compared to 13.9% of the aspirin group and 16.9% of the oral anticoagulants group. Addition of dipyridamole to 50 mg/day aspirin did not significantly improve patency rates and increased the overall clinical events rate. Oral anticoagulants provided no benefit as compared to aspirin. In a subgroup of 127 patients, there were no differences in symptoms of angina pectoris or exercise capacity between the three groups
