Cardiomyopathy is disease of abnormal heart muscle in which the heart muscle becomes weakened, stretched, or has another structural problem. It often contributes to the heart's inability to pump or function well.
Many people with cardiomyopathy have heart failure.
There are many types of cardiomyopathy, with different causes. Some of the more common ones are:
When possible, the cause of cardiomyopathy is treated. Medicines and lifestyle changes are often needed to treat the symptoms of heart failure, angina and abnormal heart rhythms.
Procedures or surgeries may also be used, including:
Partially and fully implantable mechanical heart pumps have been developed. These may be used for very severe cases. However, not all people need this advanced treatment.
The outlook depends on many different things, including:
Heart failure is most often a long-term (chronic) illness. It may get worse over time. Some people develop severe heart failure. In this case, medicines, surgery, and other treatments may no longer help.
People with certain types of cardiomyopathy are at risk for dangerous heart rhythm problems.
