Hypertrophic Cardiomyopathy (HCM) Resource Guide

At a Glance

Hypertrophic cardiomyopathy (HCM) is a genetic heart condition that causes thickening of the heart muscle. Although it is a lifelong diagnosis, modern treatments—including medications and specialized procedures—allow the vast majority of patients to live a full and normal lifespan.

Receiving a diagnosis of Hypertrophic Cardiomyopathy (HCM) can feel overwhelming. This guide is designed to empower you with evidence-based information so you can understand your condition, advocate for your care, and collaborate with your medical team.

HCM is a lifelong genetic heart condition, but with modern medical care, the majority of people live a full, normal lifespan. Navigating the initial diagnosis, understanding your test results, and exploring treatment options can be complex. We have broken this information down into manageable sections.

Common questions in this guide

Is Hypertrophic Cardiomyopathy (HCM) a fatal condition?
While HCM is a lifelong genetic heart condition, it is highly manageable. With modern medical care and appropriate monitoring, the vast majority of people diagnosed with HCM live a full, normal lifespan.
Do my family members need to be tested for HCM?
Yes, because HCM is an inherited genetic condition, it can be passed down through families. You should discuss your diagnosis with your doctor to determine when and how your close family members should be screened.
What are the different types of HCM?
HCM is generally categorized into two main subtypes: obstructive and non-obstructive. Understanding which subtype you have is critical, as it determines which symptoms you may experience and which treatments will be most effective for you.
What are the standard treatments for hypertrophic cardiomyopathy?
Treatment varies based on your specific symptoms and subtype. Common approaches include standard heart medications, targeted drugs like myosin inhibitors, and procedures such as septal reduction therapies or the placement of an implantable cardioverter-defibrillator (ICD).
Should I go to a specialized Center of Excellence for my HCM care?
Because HCM involves complex genetics and specialized treatment options, many patients benefit from visiting a Center of Excellence. These specialized clinics have extensive experience in diagnosing, monitoring, and treating hypertrophic cardiomyopathy.
