Some chest pain may also be associated with this disease. The liver may be enlarged. Neck veins may be distended. Heart biopsy may be helpful to distinguish dilated cardiomyopathy from other diseases. Lab tests vary depending on the suspected cause.
Treatment is focused on relief of symptoms.
Digitalis or other cardiac medications, diuretics, nutritional supplements, and other medications may be prescribed to reduce symptoms. A low-salt diet may be prescribed and fluid may be restricted in some cases. Activity may often continue as tolerated. A heart transplant may be considered if the heart function is very poor. Daily monitoring of body weight may be advised.
