title: [Treatment of patients with exercise-induced angina pectoris with korinfar and isoptin].
abstract: Forty-eight patients with stable angina of effort of II and III functional classes were investigated to compare the efficacy of the calcium antagonists corinfar and isoptin, using placebo and a simple cross-over design of the study. The two drugs were found to have a high antianginal effect expressed in a statistically significant reduction of the incidence of anginal attacks and an increased tolerance to load as compared to placebo. The degree of the antianginal action of corinfar in a daily dose of 40 mg and isoptin in a dose of 240 mg was approximately the same. In some patients the antianginal effect of corinfar and isoptin was associated with an elevation in the pulse-pressure index at the peak of the load, which may be accounted for by the direct coronarodilatory action of these drugs.
