Overview

There are many causes of dilated cardiomyopathy. The most common cause is idiopathic in 50% of cases. The next most common cause is myocarditis which is responsible for 10% of cases. The high percentage of idiopathic dilated cardiomyopathy may be related to the difficulty in diagnosing viral myocarditis. Other common causes include substance abuse, connective tissue disease, pregnancy, medications, nutritional deficiencies, infiltrative diseases and toxins. There are varying degrees of severity of the disease. Some forms are reversible and some are irreversible; some patients may be completely asymptomatic and some may require cardiac transplantation.
