Restrictive Cardiomyopathy

Restrictive cardiomyopathy, the rarest form of cardiomyopathy in which the walls of the lower chambers of the heart (the ventricles) become very rigid and lack the flexibility to expand as the ventricles fill with blood. As time passes, the heart loses the ability to pump blood properly, which leads to heart failure.

The causes for restrictive cardiomyopathy are

  • Buildup of scar tissue
  • Abnormal levels of proteins in the heart muscle
  • chest exposed to radiation
  • Excess iron in the heart

Symptoms for restrictive cardiomyopathy are

  • Shortness of breath
  • Fatigue
  • Inability to exercise
  • Swelling of the legs and feet
  • Weight gain
  • Bloating, which is related to fluid retention
  • Palpitations

Restrictive cardiomyopathy treatments include

Medications: Drugs like beta-blocker and angiotensin-converting enzyme (ACE) inhibitor are used in treating the symptoms of restrictive cardiomyopathy and also managing heart failure.

In severe conditions, heart transplant surgery may be considered for restrictive cardiomyopathy.
