Cardiomyopathy Symptoms

Call 9-1-1 if you are having trouble breathing or your symptoms last longer than a few minutes.

Some people with cardiomyopathy never have any symptoms. Other people may not have symptoms until the condition gets worse.

Common symptoms include the following:

  • Shortness of breath
  • Chest pain, especially after physical activity or heavy meals
  • Tiredness even after resting
  • Dizziness and fainting
  • Arrhythmias (irregular heartbeats)
  • Heart murmurs (extra or unusual sounds heard during a heartbeat)

Babies and young children may experience vomiting, diarrhea, difficulty eating and breathing, fussiness, and poor growth.

If your cardiomyopathy has caused heart failure, you may also have swelling in your stomach area, hands, legs, and feet. You may also have these symptoms if you have cardiomyopathy during pregnancy.
