title: [Dipyridamole and low-dose aspirin in patients with aortocoronary bypass--comparison with anticoagulation].
abstract: The effects of antiplatelet therapy (AP; dipyridamole 400 mg [beginning 2 days preoperatively] + aspirin 50 mg/day) and anticoagulation (AC) were compared prospectively in 251 patients with coronary artery bypass grafting (CABG). Two weeks postoperatively, 85.2% of AP and 81% of AC patients had all grafts patent with graft patency rates of 93.6% and 91.3% respectively (p = n.s.) Significant differences in favour of AP therapy were found in subgroups with multiple grafts and with low intraoperative graft flow. Up to 3 months postoperatively, severe complications occurred in 22 AC patients (11 bleedings) but only in 9 patients on AP therapy (p less than 0.01). Overall, AP therapy should therefore be preferred to AC in patients with CABG surgery.
