Enteroviruses, especially coxsackievirus B, and adenovirus and parvovirus B19 are often associated with acute myocarditis. Exposure to drug treatment, physical stimuli such as radiation and heat, metabolic disorders, immune disorders, and pregnancy are also causes of myocarditis. Many cases of myocarditis are idiopathic. Myocarditis presents with non-specific symptoms including chest pain, dyspnea, and palpitations, and thus often mimics more common disorders such as coronary artery disease. In some patients, cardiac MRI and endomyocardial biopsy can help identify myocarditis, predict risk of cardiovascular events, and guide treatment. UMLS:C0027059 Inflammation of the myocardium.
