IntroductionMyocarditis is a serious condition that carries with it a high rate of morbidity and mortality.ObjectiveThis review highlights the pearls and pitfalls of myocarditis, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.DiscussionMyocarditis is an inflammatory syndrome of myocardium, most often resulting from a viral infection, that can cause life-threatening cardiovascular collapse. It has a highly variable presentation and no widely available specific diagnostic test, making it a challenging diagnosis. Emergency clinicians should obtain an electrocardiogram and perform bedside ultrasound to assess cardiac function. Treatment in the ED is largely supportive, focusing on resuscitation, cardiovascular support, cardiology specialist consultation, and appropriate disposition.ConclusionsAn understanding of myocarditis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.Published by Elsevier Inc.
