Cardiomyopathy is a disease of the heart muscle that may becomes stretched (enlarged) or abnormally thick or rigid. Sometimes extensive scarring occurs.
There are three types of cardiomyopathy:
The terms Systolic or Diastolic dysfunction are often used to describe where in your heart cycle this occurs:
A dilated cardiomyopathy can be inherited or caused by a variety of diseases that include :
- Coronary artery disease and previous heart attacks (ischemic cardiomyopathy)
- Infections, especially viral infections that cause the heart muscle to become inflamed (myocarditis)
- Alcohol, especially when a person has a poor diet (alcoholic cardiomyopathy)
- Complications during the last month of pregnancy or within 5 months of birth (peripartum cardiomyopathy)
- Certain drugs, such as cocaine, amphetamines, and some cancer medications
- Diseases such as diabetes and thyroid disease
- Hemochromatosis, a condition in which too much iron is deposited into tissues, including heart tissue
- Amyloidosis, a disease in which abnormal proteins are deposited into heart tissue
- Sarcoidosis, a disease in which inflammation produces tiny lumps of cells in various organs in the body, including the heart
- Connective tissue disorders
Not everyone with cardiomyopathy needs treatment and some patients recover on their own. Patients without symptoms may not need treatment.
