Cardiomyopathy refers to a disease caused to the heart muscle. These diseases have many and different causes, signs and symptoms, and treatments which may differ with person to person and may be required to do so.

In cardiomyopathy, the heart muscles swell out becoming enlarged from their original size, thick, or rigid which disrupt the normal functioning of the heart. In rare cases, the muscle tissue which is affected in the heart is replaced by or with scar tissue.

As cardiomyopathy worsens, the heart becomes weaker and it becomes difficult for it to function properly. It becomes less able to pump enough blood through the body and maintain a normal count of electrical rhythm. This can lead to heart failure in some case or irregular heartbeats in other called arrhythmias. In turn, heart failure can cause the fluid to build up in the legs, lungs, feet, ankles, feet, or abdomen.

The weakening of the heart can also cause other complications to the person, such as heart valve problems.


In the early stages of the disease, people with cardiomyopathy may not have or show any signs and symptoms to the person. But as the condition advances to higher stages, signs and symptoms usually start to appear. Cardiomyopathy signs and symptoms may include:

  • Breathlessness with physical exertion or even at rest

  • Swelling of the legs, ankles, and feet

  • Bloating of the abdomen due to buildup of fluid

  • Fatigue

  • Cough while lying down to rest

  • Irregular heartbeat that feels rapid, pounding or fluttering

  • Pain in Chest

  • Fainting, Dizziness, and lightheadedness

No matter what type of cardiomyopathy we have, signs and symptoms tend to get worse unless they are treated. In certain people, this worsening happens quickly, while in others, cardiomyopathy cannot worsen for a long time.


Often, the cause leading to the cardiomyopathy is unknown. In some people, however, the doctor is able to identify it some contributing factors. Possible causes of cardiomyopathy include:

  •     Genetic condition
  • Long-term high blood pressures

  • Heart tissue damages from the previous heart attacks

  • Chronic rapid heart rates

  • Heart valve problem

  • Metabolic disorder, such as obesity, thyroid disease or diabetes

  • Nutritional deficiencies of the essential vitamins or minerals, such as thiamin (vitamin B-1)

  • Pregnancy complication

  • Drinking too much of alcohol over many years

  • Use of the cocaine, amphetamines or anabolic steroids

  • Use of some the chemotherapy drugs and radiation to treat the cancer

  • Certain infections, which can injure the heart and trigger cardiomyopathy
