Hypertrophic cardiomyopathy is a condition where the heart muscle becomes thick. It is often caused by gene mutations in the heart muscle. The thickened heart muscle can become stiff, reducing the heart's ability to pump blood adequately.
Your doctor may ask these questions to check for this disease:
There is currently no specific medication for hypertrophic cardiomyopathy. Treatment focuses on controlling symptoms and reducing the risk of complications with medications and lifestyle changes.

Q.
Chest Pain? Hypertrophic Cardiomyopathy: Medically Approved Next Steps
A.
There are several medically important steps to consider if chest pain raises concern for hypertrophic cardiomyopathy: treat severe or sudden symptoms as an emergency, and otherwise arrange a prompt evaluation with a clinician. See below for red flag symptoms, what to tell your doctor, and why ruling out a heart attack matters. Below you will also find the standard tests used to confirm HCM, how doctors assess risks like arrhythmia and sudden cardiac arrest, the full range of treatments from medications to septal reduction or an ICD, plus lifestyle guidance and when to pursue family screening and genetic testing.
