Cardiomyopathy includes diseases of the heart muscle that reduce the heart’s ability to pump effectively. These diseases enlarge your heart muscle or make it thicker and more rigid than normal.

There are many types of cardiomyopathy. Some of the more common are:

  • Dilated cardiomyopathy - a condition in which the heart becomes weak and the chambers get large. As a result, the heart cannot pump enough blood out to the body.
  • Hypertrophic cardiomyopathy - a condition in which the heart muscle becomes thick. This makes it harder for blood to leave the heart.
  • Ischemic cardiomyopathy - caused by a narrowing of the arteries that supply the heart with blood. It makes the heart walls thin so they do not pump well.
  • Restrictive cardiomyopathy - a group of disorders. The heart chambers are unable to fill with blood because the heart muscle is stiff.
  • Peripartum cardiomyopathy - occurs during pregnancy or in the first 5 months afterward.

The causes of cardiomyopathy are not always known. It can be inherited, meaning that it’s caused by genes passed down from your parents. It can also be acquired, meaning that you develop it because of another condition or risk factor.

Cardiomyopathy Risk Factors

Conditions and risk factors that may lead to cardiomyopathy include:

Cardiomyopathy Symptoms

As cardiomyopathy progresses and the heart weakens, signs and symptoms of heart failure usually occur. These include:

  • Shortness of breath or trouble breathing, especially with physical activity
  • Fatigue
  • Swelling in the feet, ankles, legs, abdomen or veins in the neck
  • Abdominal bloating caused by fluid buildup
  • Cough
  • Irregular heartbeats
  • Dizziness, lightheadedness or fainting

Because cardiomyopathy weakens the heart, it’s important to get treated. Treatment can prevent the disease from getting worse, control symptoms and reduce your risk for serious complications, including:
