Abstract

In a prospective pilot trial of antithrombotic therapy in the acute coronary syndromes (ATACS) of resting and unstable angina pectoris or non-Q-wave myocardial infarction, 3 different antithrombotic regimens in the prevention of recurrent ischemic events were compared for efficacy. Ninety-three patients were randomized to receive aspirin (325 mg/day), or full-dose heparin followed by warfarin, or the combination of aspirin (80 mg/day) plus heparin and then warfarin. Trial antithrombotic therapy was added to standardized antianginal medication and continued for 3 months or until an end point was reached. Analysis, by intention-to-treat, of the 3-month end points, revealed the following: recurrent ischemia occurred in 7 patients (22%) after aspirin, in 6 patients (25%) after heparin and warfarin, and in 16 patients (43%) after aspirin combined with heparin and then warfarin; coronary revascularization occurred in 12 patients (38%) after aspirin, in 12 patients (50%) after heparin and warfarin, and in 22 patients (60%) after aspirin combined with heparin and then warfarin; myocardial infarction occurred in 1 patient (3%) after aspirin, in 3 patients (13%) after heparin and warfarin, and in no patient after aspirin combined with heparin and then warfarin; no deaths occurred after aspirin or after aspirin combined with heparin and then warfarin, but 1 patient (4%) died after warfarin alone; major bleeding occurred in 3 patients (9%) after aspirin, in 2 patients (8%) after heparin and warfarin, and in 3 patients (8%) after aspirin combined with heparin and then warfarin. Recurrent myocardial ischemia occurred at 3 +/- 3 days after randomization.(ABSTRACT TRUNCATED AT 250 WORDS).
