Cardiomyopathy is any disease of the heart muscle that impairs the ability of the heart to pump normally. Cardiomyopathy may result in heart failure, where the heart can’t pump as much blood as the body needs.
Cardiomyopathy: What You Need to Know
- One common cause of cardiomyopathy is lack of blood flow to the heart muscle, usually as a result of a heart attack. Other causes include excess alcohol consumption, nutritional or hormonal imbalances, viral infection of the heart, chemotherapy and certain inherited diseases.
- Symptoms may not appear until the disease is at an advanced stage.
- Diagnosis may involve multiple tests. Some are noninvasive, such as an echocardiogram (ultrasound) or X-ray. Other tests may involve a biopsy of the heart or inserting a catheter (a thin plastic tube) through a blood vessel into the heart to inject dye or take measurements.
- Your doctor will treat any underlying conditions. Sometimes a heart transplant may be necessary.
