The treatment of dilated cardiomyopathy is primarily concerned with that of congestive heart failure. Digitalis is widely use in dilated cardiomyopathy but an improvement in the prognosis has not yet been demonstrated. Furthermore, the effects of digitalis in patients with sinus rhythm are debatable. ⋯ Unlike other substances, ACE inhibitors have been demonstrated to improve prognosis of patients with congestive heart failure. At present, combined diuretic therapy and angiotensin conversion enzyme inhibition would seem the most reasonable treatment for patients with dilated cardiomyopathy and sinus rhythm. If atrial fibrillation and tachyarrhythmia develop, additional digitalis therapy is effective.
