title: Therapeutic management of dilated cardiomyopathy.
abstract: The therapeutic approach to dilated cardiomyopathy (DCM) still remains nonspecific and symptomatic, since no specific etiology is identified. Nevertheless, the recent introduction of angiotensin converting enzyme (ACE) inhibitors and beta-blockers greatly improved the treatment of DCM. The poor prognosis of patients with DCM encourages maximal aggressive attempts to prevent progression of ventricular dysfunction rather than to wait for treatable symptoms. To achieve this goal, vasodilators, particularly ACE inhibitors, now appear to be essential for the treatment of DCM. Digitalis is added unless contraindicated by adverse effects. Diuretics should be used only to relieve congestive symptoms. In the presence of sinus tachycardia or ventricular arrhythmias, beta-blockers are the next choice in our practice. When congestive symptoms or low output state are not controlled with vasodilators, diuretics, and digitalis, inotropic agents are indicated, with or without mechanical assist devices. For severely ill patients unresponsive to maximal medical management, heart transplantation is needed.
