Etiology, evaluation, and management of acute myocarditis

Abstract

The evaluation and management of acute myocarditis remain two of the most difficult challenges that general internists and cardiologists face today. Although the majority of cases are subclinical and self-limited, the true prevalence of myocarditis in the general population is unknown. In its most severe form, patients with myocarditis may present with rapidly progressive heart failure, cardiogenic shock, or complex arrhythmia. Indeed, acute myocarditis should be in the differential diagnosis of acute heart failure, particularly in young and previously healthy individuals.
