What is Cardiomyopathy?
Cardiomyopathy refers to diseases of the heart muscle. The heart muscle becomes enlarged, thick or rigid in cardiomyopathy, and in rare cases the muscle tissue is replaced with scar tissue. As the condition worsens, the heart becomes weaker and less able to pump blood through the body and maintain a normal electrical rhythm. The result can be heart failure
or irregular heartbeats called arrhythmias
. A weakened heart also can cause other complications, such as heart valve problems.
