How is hypertrophic cardiomyopathy (HCM) diagnosed?
The diagnosis of HCM is based on:
- Medical history: Your doctor will ask you questions about your symptoms and family history.
- Physical exam: Your doctor will listen to your heart and lungs. Patients with hypertrophic obstructive cardiomyopathy (HOCM) may have a heart murmur.
- Tests: An echocardiogram is the most common test used to diagnose HCM, as the characteristic thickening of the heart walls is usually visible on the echo. Other tests may include blood tests, electrocardiogram, chest X-ray, exercise stress echo test, cardiac catheterization and magnetic resonance imaging (MRI).
