What is the most common cause of restrictive cardiomyopathy?
Amyloidosis, an abnormal buildup of protein in organs and tissues. This is the most common cause of RCM. Hemochromatosis, a condition that occurs from an iron overload in the heart and body. Sarcoidosis, a disease that causes scarring of the heart.
What are the symptoms of restrictive cardiomyopathy?
Symptoms and Causes Shortness of breath (at first with exercise; but over time it occurs at rest) Fatigue (feeling overly tired) Inability to exercise. Swelling of the legs and feet.
How long can you live with restrictive cardiomyopathy?
Outlook (Prognosis) People with restrictive cardiomyopathy may be heart transplant candidates. The outlook depends on the cause of the condition, but it is usually poor. Survival after diagnosis may exceed 10 years.
What diseases are common causes of restrictive cardiomyopathy?
Other causes of restrictive cardiomyopathy include:
- Cardiac amyloidosis.
- Carcinoid heart disease.
- Diseases of the heart lining (endocardium), such as endomyocardial fibrosis and Loeffler syndrome (rare)
- Iron overload (hemochromatosis)
- Sarcoidosis.
- Scarring after radiation or chemotherapy.
- Scleroderma.
- Tumors of the heart.
Is there a cure for restrictive cardiomyopathy?
Restrictive cardiomyopathy (RCM) has no specific treatment.
Can you reverse restrictive cardiomyopathy?

- Quitting smoking.
- Losing excess weight.
- Avoiding alcohol and illegal drugs.
- Getting enough sleep and rest.

- Treating underlying conditions, such as diabetes and high blood pressure.
Is restrictive cardiomyopathy a rare disease?
Restrictive cardiomyopathy (RCM) is a rare disease of the myocardium and is the least common of the three clinically recognized and described cardiomyopathies. It is characterized by diastolic dysfunction with restrictive ventricular physiology, whereas systolic function often remains normal.
Which is a secondary cause of restrictive cardiomyopathy?
Causes of secondary restrictive cardiomyopathy include infiltrative diseases (eg, amyloidosis, sarcoidosis, radiation carditis) and storage diseases (eg, hemochromatosis, glycogen storage disorders, Fabry’s disease).
