Abstract

Aims. To compare the efficacy and tolerability of the antiplatelet agent triflusal with aspirin in the prevention of cardiovascular events following acute myocardial infarction. Methods and Results. In this double-blind, multicentre, sequential design study, patients were randomized within 24 h of acute myocardial infarction symptom onset to receive triflusal 600 mg or aspirin 300 mg once daily for 35 days. The primary end-point was death, non-fatal myocardial reinfarction or a non-fatal cerebrovascular event. The incidences of these individual outcomes and urgent revascularization were secondary end-points. The null hypothesis of no difference between treatments in the primary combined end-point was accepted with 80% power after recruiting 2124 validated patients (odds ratio (OR) for failure [95% confidence interval (CI)]: 0.882 [0.634-1.227]). Non-fatal cerebrovascular events were significantly less frequent with triflusal (OR [95% CI]: 0.364 [0.146-0.908]; P = 0.030). There was no significant difference between treatments for death (OR [95% CI]: 0.816 [0.564-1.179]; P = 0.278), non-fatal reinfarction (OR [95% CI]: 1.577 [0.873-2.848]; P = 0.131) or revascularization (OR [95% CI]: 0.864 [0.644-1.161]; P = 0.334). Overall, both drugs were well tolerated, although there was a trend towards fewer bleeding episodes with triflusal; significantly fewer central nervous system bleeding episodes were observed in triflusal-treated patients (0.27% vs 0.97%; P = 0.033). Conclusion. Triflusal and aspirin have similar efficacy in preventing further cardiovascular events after acute myocardial infarction, but triflusal showed a more favourable safety profile. Triflusal significantly reduced the incidence of non-fatal cerebrovascular events compared with aspirin. (C) 2000 The European Society of Cardiology.
