Quick answer
What is Cardiomyopathy?
Cardiomyopathy is a disease of the heart muscle itself, which becomes structurally abnormal — for example stretched and weakened (dilated), thickened (hypertrophic), or stiff (restrictive). This affects how effectively the heart pumps blood and can lead to heart failure, abnormal rhythms and, in some types, a raised risk of sudden problems.
- How it is treated: Treatment depends on the type and severity, and aims to relieve symptoms, support heart function, control rhythm problems and reduce risks.
- Self-care: Limiting alcohol, treating high blood pressure, staying active within advised limits, and following specialist guidance on exercise (which differs by type) all help.
- When to seek help: See a doctor about unexplained breathlessness, palpitations or swollen ankles.
What it is
Cardiomyopathy is a disease of the heart muscle itself, which becomes structurally abnormal — for example stretched and weakened (dilated), thickened (hypertrophic), or stiff (restrictive). This affects how effectively the heart pumps blood and can lead to heart failure, abnormal rhythms and, in some types, a raised risk of sudden problems. Some cardiomyopathies are inherited, so relatives may be screened; others result from causes such as previous heart damage, high blood pressure, alcohol or viral illness. Symptoms include breathlessness, tiredness, swollen ankles, palpitations and, in some, blackouts. Diagnosis uses an ECG, echocardiogram (heart ultrasound), and sometimes an MRI and genetic testing.
How it is treated
Treatment depends on the type and severity, and aims to relieve symptoms, support heart function, control rhythm problems and reduce risks. Many people are treated with the medicines used for heart failure to ease the heart's workload and improve outcomes. Rhythm problems may need specific treatment, and some people benefit from implanted devices (such as a defibrillator) to protect against dangerous rhythms. Inherited types involve family screening and lifestyle advice. Care is usually led by a cardiology team and tailored to the individual.
