What is restrictive cardiomyopathy?

Restrictive cardiomyopathy is a disease of heart muscle that prevents the muscle from contracting (squeezing) with normal force.

When restrictive cardiomyopathy occurs, the heart has a restricted ability to contract because the inner lining of the heart becomes stiff. The result is that the heart doesn’t pump blood well. .Cardiomyopathy can lead to heart failure.

Know the causes

What causes restrictive cardiomyopathy?

Restrictive cardiomyopathy is a rare disease. The most common cause is degeneration of starch (condition of abnormally high protein and blood cells) and unexplained scarring in the heart (myocardial fibrosis primary). The disease can also occur after a heart transplant.

Other causes of restrictive cardiomyopathy include:

  • Carcinoid heart disease
  • Diseases of the heart lining (endocardium), such as endomyocardial fibrosis and Loeffler’s syndrome (rare)
  • Iron overload (hemochromatosis)
  • Sarcoidosis
  • Scarring after radiation or chemotherapy
  • Scleroderma
  • Tumors of the heart

Know the risk factors

What increases my risk for restrictive cardiomyopathy?

Certain factors may increase your risk of developing Restrctive cardiomyopathy:

  • Family history. People with a family history of cardiomyopathy, heart failure and sudden cardiac arrest are more likely to develop cardiomyopathy than are those without a family history of heart problems.
  • Obesity. Excess weight makes the heart work harder, which may increase the risk of cardiomyopathy and heart failure.
  • Alcoholism. People who abuse alcohol can damage their hearts, and cardiomyopathy can be a consequence. The risk increases significantly after more than five years of drinking seven to eight drinks daily.
  • Illicit drug use. Drugs, such as cocaine, amphetamines and anabolic steroids, may increase the risk of cardiomyopathy
  •  Certain chemotherapy drugs and radiation therapy can increase the risk of cardiomyopathy.
  • Diabetes and Thyroid disorders.
  • Hemochromatosis. This disorder causes the body to store excess iron, and it has been linked to an increased risk of dilated cardiomyopathy.

Not having risk factors does not mean you can not get hamstring strians. These factors are for reference only. You should consult  your doctor for more details.

The doctor may also order echocaradiography (ultrasound examination of the heart) to check the heart’s pumping action. Blood tests may also be done to look for other causes.

Besides, in some cases, cardiac catheterization and biopsy of heart tissue may be done to confirm the diagnosis.

How is restrictive cardiomyopathy treated?

Treatment is aimed at relieving symptoms of heart failure ad correcting abnormal heart rhymths (arrhythmias)

Treatment theraphy may include:

Medications known as diuretics reduce fluid I the blood to decrease the work of the heart

The doctor may prescribe drugs that regulate the heartbeat or drugs that suppress immune function (corticosteroids) to fight conditions causing the cardiomyopathy.

  • Chemotherapy (in some situations)

If the heart’s pumpig is very poor and symptoms of heart failure worsen, heart transplantation may be needed.
