Cardiomyopathy is a broad term for diseases of the heart muscle. It may sound intimidating, but understanding the different types and how we treat them can take away some of the fear.

There are three primary types:

  1. Dilated Cardiomyopathy: The heart chambers enlarge and can’t pump blood effectively. This is the most common form and often leads to heart failure.
  2. Hypertrophic Cardiomyopathy: The heart muscle thickens, making it harder for the heart to pump. It can be genetic and is a leading cause of sudden cardiac death in young athletes.
  3. Restrictive Cardiomyopathy: The heart becomes stiff and less flexible, limiting how it fills with blood.

Causes can vary and include genetics, viral infections, chronic high blood pressure, alcohol abuse, chemotherapy, and unknown factors can all play a role.

Symptoms include:

  • Shortness of breath
  • Fatigue
  • Swelling in the legs
  • Irregular heartbeats
  • Chest pain

Diagnosis involves EKGs, echocardiograms, MRIs, and sometimes genetic testing. Treatment depends on the type and severity but may include medications, lifestyle changes, or devices like defibrillators or pacemakers. In severe cases, a heart transplant may be considered.

With early detection and good management, many people live full lives with cardiomyopathy. It’s not a death sentence, it’s a diagnosis that empowers you to take control.
