Overview

Supportive measures

Physical activity may continue as long as the patient can tolerate it.

Diet restrictions vary with the extent of cardiomyopathy and heart failure. These may include salt and/or fluid restrictions.

Pharmacotherapy

Diuretics (water pills) may be given to remove excess fluid.

Digoxin may be used cautiously to improve heart control in patients with atrial fibrillation.

Daily weight measurement may be recommended. A weight gain of 3 or 4 pounds or more over 1 or 2 days can indicate excessive fluid accumulation.

Some people benefit from chemotherapy or prednisone.

Pacemaker

A pacemaker may be needed if the conduction system is involved.
