when our heart is abnormally enlarged or hardened. Due to which the ability of the heart muscle to pump blood decreases, due to which the heart rate can stop. And there is a backup of blood in the lungs or the rest of the body, which we call cardiomyopathy or heart muscle disease.

It is a type of progressive heart disease. It can also cause abnormal heart rhythm, heart failure, and valvular heart disease.   Cardiomyopathy is called weakness of the heart in simple language.


The main cause of cardiomyopathy is still unknown. But in some people, it may be due to the following reasons.


  1. Inherited from parents.
  2. Prolonged hypertension.
  3. Lack of essential vitamin or mineral nutrients.
  4. Heart tissue loss due to heart attack.
  5. Complication in pregnancy.
  6. Obesity, having a metabolic disorder such as thyroid disease or diabetes.
  7. Heart valve problem.
  8. Too much alcohol consumption.
  9. Use of cocaine, amphetamine or anabolic steroids.
  10. Heart – building infection.
  11. Lumps of cells in the heart and other organs cause inflammatory condition.
  12. Use of chemotherapy drugs and radiation.
  13. Iron buildup in heart muscle.
  14. Disorders caused by abnormal protein formation.
  15. Infection of COVID-19 (corona virus).
  16. Connective tissue disorder.


There are mainly 5 types of cardiomyopathy disease

  1. Dilated cardiomyopathy (DCM) :-

When the heart muscle becomes thin, or the lower left chamber of the heart becomes large and thin, the heart becomes unable to filter blood efficiently, reducing the amount of blood in the body. Such a condition is called dilated cardiomyopathy.

  1. Hypertrophic cardiomyopathy (HCM) :-

When the lower left chamber of the heart becomes thick, or when the muscles become thick, it can block blood flow to the aorta. This is called “outflow tract obstruction”. And this condition is called hypertrophic cardiomyopathy.

  1. Restrictive cardiomyopathy (RCM) :-

When the heart muscle becomes stiff, causing the blood becomes restless or unable to stretch and fill the blood. Which causes abnormal heart rhythm and heart failure symptoms? Such a condition is called restrictive cardiomyopathy.

  1. Left ventricular Non – Compaction cardiomyopathy (LVNC) :-

When the bundles or pieces of muscle in the lower left chamber of the heart become enlarged. Which is called left ventricular noncondensate cardiomyopathy.

  1. Arrhythmogenic Right Ventricular Dysplasia (ARVD) :-

When the lower right chamber of the heart is enlarged and causes contraction problems, the heart is not able to pump blood properly. This can increase the risk of arrhythmia, sudden cardiac arrest, or death. We call this arrhythmogenic right ventricular dysplasia.


Symptoms of cardiomyopathy are seen only when there is an increase in its condition, its symptoms are not detected in the initial stages.

Its symptoms include:-

  1. To be tired.
  2. Feeling of a heartbeat or tremor.
  3. Swelling of ankles and feet.
  4. Chest discomfort even to rest.
  5. Dizziness, laziness and fainting.
  6. Flatulence due to fluid buildup.
  7. Cough while sleeping or lying down.
