Get StartedSymptoms
By Mayo Clinic staffSome people who develop cardiomyopathy may have no signs and symptoms in the early stages of the disease. But as the condition advances, signs and symptoms usually appear. Signs and symptoms of cardiomyopathy may include:
- Breathlessness with exertion or even at rest
- Swelling of the legs, ankles and feet
- Bloating (distention) of the abdomen with fluid
- Fatigue
- Irregular heartbeats that feel rapid, pounding or fluttering
- Dizziness, lightheadedness and fainting
No matter what type of cardiomyopathy you have, signs and symptoms tend to get worse unless treated. In certain people, this worsening happens quickly; while in others, the disease may not worsen for a long time.
