Cardiomyopathy is a broad term describing cardiac muscle illnesses in which the heart chamber walls have become stretched, thickened, or rigid. This has an impact on the heart’s ability to circulate blood throughout the body.

Cardiomyopathy is caused by defective heart muscle, not by blocked arteries in the heart (coronary artery disease), high blood pressure (hypertension), disease of the heart valves (valvular disease), or congenital heart disease.

The majority of cardiomyopathies are hereditary and manifest themselves in children and young adults.
Cardiomyopathy diagnosis
Cardiomyopathy can be detected using a variety of cardiac scans and tests, including:

electrocardiography (ECG) (ECG)

echocardiogram

Magnetic resonance imaging (MRI)

monitor your heartbeat (24 or 48-hour ECG monitor)

tests of physical activity

For the diagnosis of cardiomyopathy, a complete family tree constructed by specialists may be required.

Changes in your way of life
Regardless of whether cardiomyopathy is caused by genetics or not, it should typically benefit to:

Eat a balanced diet and get some mild exercise.

smoking cessation (if you smoke)

if you’re overweight, lose weight

Alcohol should be avoided or consumed in moderation.

get adequate rest (as well as diagnose and treat any underlying sleep apnoea)

control your anxiety

Ascertain that any underlying conditions, such as diabetes, are adequately managed.
