title: Efficacy of isosorbide-5-mononitrate versus nifedipine in preventing spontaneous and ergonovine-induced myocardial ischaemia. A double-blind, placebo-controlled study.
abstract: This study was designed to assess the efficacy of oral nifedipine as compared to oral isosorbide-5-mononitrate in the prevention of spontaneous and induced vasospastic myocardial ischaemia. Twenty-one patients admitted to the Coronary Care Unit as a result of angina at rest underwent both Holter monitoring and an echo-ergonovine test during placebo and following either isosorbide-5-mononitrate or nifedipine according to a double-blind randomized trial. Both drugs caused a statistically significant reduction in spontaneous (87% and 95%, respectively) and induced ischaemic attacks (66% and 75%, respectively). No significant difference was found between the two drugs.
