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.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
