Abstract

A total of 109 male patients with acute transmural myocardial infarction (MI) were studied. 26 patients received a dose of acetylsalicylic acid (aspirin, ASA) 500 mg/d and 29 patients of 50 mg/d. 27 patients were given diclofenac (25 mg/d). 27 patients received no antiplatelet therapy. We observed thrombocyte hyperaggregation on the 1st MI day, a rapid increase in platelet activity by the 7th day and a considerable decrease in platelet aggregation during the 3rd and 4th weeks of illness in the group without antiaggregative treatment. The present study clearly demonstrated high antiaggregatory efficacy of ASA in dose of 50 mg/d which was significantly higher than that in daily dose of 500 mg ASA. Low-dose aspirin had fewer side-effects than aspirin 500 mg/d. However, although daily dose of 50 mg aspirin significantly inhibited platelet hyperaggregation on 7th day of MI, the hyperactivity of thrombocytes was not abolished. Diclofenac 25 mg daily had only a moderate antiaggregative efficacy in acute MI patients.
