Statins as Antiarrhythmics: A Systematic Review Part II: Effects on Risk of Ventricular Arrhythmias

Background: Recent studies have demonstrated that statins may possess antiarrhythmic properties in addition to their lipid-lowering effects. Methods: Studies which reported the association of statins with the incidence of ventricular arrhythmias were identified through a systematic review of the published literature. Results: Statins have been associated with significant reduction in ventricular arrhythmia in cardiomyopathy patients with an implantable cardioverter defibrillator, although randomized trials have not been completed. Conclusions: Published data suggest that statins may possess antiarrhythmic properties that reduce the propensity for ventricular arrhythmias. Most of this data is observational; more randomized, placebo-controlled trials are needed.
