Cardiomyopathy

Also known as: Heart muscle disease Specialty: Cardiology

Overview

Cardiomyopathy is a condition affecting the heart muscle itself. The heart may become enlarged, weakened, stiff, or less able to pump blood effectively. Over time, this can affect circulation, energy levels, breathing, and overall heart function.

Some people develop symptoms gradually, while others may only discover the condition during evaluation for heart-related symptoms or routine testing. Cardiomyopathy may be linked to inherited conditions, infections, high blood pressure, or other heart diseases.

With proper monitoring and treatment, many people are able to manage symptoms and support long-term heart function.

Symptoms

Symptoms can vary depending on the type and severity of cardiomyopathy. You may experience:

  • Shortness of breath
  • Fatigue or reduced exercise tolerance
  • Swelling of the legs or feet
  • Chest discomfort
  • Palpitations or irregular heartbeat
  • Dizziness or fainting episodes

Some people may have mild symptoms early in the condition.

Causes & Risk Factors

  • Have a family history of heart muscle disease
  • Have long-standing high blood pressure
