idiopathic dilated cardiomyopathy

Abbreviation: IDC
Cardiomyopathy of occult or uncertain cause, possibly due to viral infections, unrecognized toxic exposures, or a genetic predisposition, but not to ischemia, hypothyroidism, hypertension, valvular disease, or alcohol abuse.

Treatment

General supportive therapy includes rest, weight control, abstinence from tobacco, and moderate exercise at a level that does not cause symptoms. A salt-restricted diet is recommended. Therapy includes the use of vasodilators, such as ACE inhibitors, and diuretics like furosemide. Anticoagulants are important to prevent thrombus formation. IDC is a principal indication for cardiac transplant.
