Human studies have found biopsy evidence of cardiac inflammation in adults with idiopathic dilated cardiomyopathyAntiviral therapy might have its greatest efficacy in the very early stages of myocarditis. Myocarditis in children and detection of viruses in myocardial tissue: implications for immunosuppressive therapy. Pediatric myocarditis is a common pediatric illness most commonly secondary to a preceding viral infection. Unable to load your collection due to an error Treatment of viral myocarditis is mainly supportive, with debatable role of anti-inflammatory, immunosuppressing immunomodulators and anti-viral therapy.

Myocarditis can affect your heart muscle and your heart's electrical system, reducing your heart's ability to pump and causing rapid or abnormal heart rhythms (arrhythmias).A viral infection usually causes myocarditis, but it can result from a reaction to a drug or be part of a more general inflammatory condition.
