Abstract

A multicenter, double-blind, randomized, placebo-controlled trial was conducted to assess the effects of verapamil on total mortality, cardiac mortality, reinfarction, and angina after an acute myocardial infarction. All patients, aged 30 to 75 years, consecutively admitted for acute myocardial infarction between 1985 and 1987 to the participating centers, and without contraindications to verapamil or history of severe heart failure were enrolled. Seven to 21 days (mean 13.8) after myocardial infarction, 531 patients were randomized to verapamil retard 360 mg/day, and 542 patients to placebo. At baseline, the 2 groups of patients had similar characteristics. Mean age was 55.5 years and 91% were men. During a mean follow-up of 23.5 months, 5.5% of the patients died. No differences between verapamil and placebo were observed in total mortality (n = 30 and 29, respectively) and cardiac death (n = 21 and 22, respectively). The verapamil group had nonsignificant lower reinfarction rates (n = 39 vs 49). The number of patients developing angina was significantly less in the verapamil group (n = 100 vs 132, RR = 0.8, 95% confidence interval 0.5 to 0.9). There were no differences in discontinuation of therapy caused by adverse reactions. This trial showed no effect of verapamil on mortality. The lower reinfarction rates found in the verapamil group are in agreement with the results of other studies.
