Effect of the Antiarrhythmic Agent Moricizine on Survival after Myocardial Infarction

Abstract

As with the antiarrhythmic agents used in CAST-I (flecainide and encainide), the use of moricizine in CAST-II to suppress asymptomatic or mildly symptomatic ventricular premature depolarizations to try to reduce mortality after myocardial infarction is not only ineffective but also harmful.
