In most cases, HCM is a genetic or inherited type of heart disease. Though patients rarely have thickening at birth, they are often born with the genetic instructions that encourage their heart to thicken abnormally over the course of their lifetime. For a small subset of patients with this condition, it can even lead to sudden cardiac death. HCM can be diagnosed at any age, but typically symptoms develop by middle age.
AHN is prepared to diagnose and treat people with hypertrophic cardiomyopathy, giving them the ability to lead a normal life once again.

While many HCM patients do not experience any symptoms from this thickening of the heart muscle, others may experience one or more of the following:
At the AHN Cardiovascular Institute, experienced and dedicated specialists provide support that you can depend on; they are subspecialty-trained providers with access to the latest diagnostic techniques and treatments, including both
medical and surgical interventions. Patients with HCM have access to expert cardiology providers who specialize in comprehensive cardiomyopathy care and imaging.
The most common way to diagnose HCM is through an echocardiogram (also known as an “echo” or “TTE”), which is an ultrasound of the heart. This is a noninvasive, painless imaging test that uses sound waves to generate a picture of your heart and valves to determine how efficiently they are working.
In some cases, an electrocardiogram (ECG/EKG) can detect unusual thickening of the heart muscle and/or abnormal heart rhythms that may be a sign of underlying HCM.
HCM is typically an inherited heart condition, with a 50% chance of being passed on to the next generation.* Most importantly, inheriting this condition from a parent carries a risk of developing HCM. A relative who carries an HCM mutation must be monitored over time with doctor visits and noninvasive imaging to detect any subtle signs of HCM appearing. Commercial testing is now available to identify the presence of a common genetic mutation as the cause of HCM. This test is performed by providing a saliva sample or, if preferred, by a blood test. It is sent to the lab for processing with results returning in three to four weeks.
This test monitors a patient’s response to physical activity and provides valuable information about changes in symptoms, heart rate, and blood pressure with exercise. It is always paired with continuous EKG monitoring to assess for abnormal heart rhythms during exercise. Most often, it is also paired with an echocardiogram to demonstrate visually how the heart and valves respond to exercise.
This test records the electrical activity of the heart over time, ranging from 24 hours to several weeks. It can help detect abnormal heart rhythms that may contribute to symptoms.
This sophisticated imaging of the heart provides additional information beyond that of an echocardiogram to guide treatment and prognosis. In addition to
identifying classic anatomic features of HCM, or even conditions that mimic HCM, it also helps identify some patients with higher-risk features for abnormal heart rhythms relating to the condition. Learn more from the American Journal of Roentgenology about using MRI for HCM.

The goal of any treatment is to relieve symptoms, protect those at higher risk of abnormal heart rhythms, and identify family members who warrant regular monitoring. Treatment may include:
Medications can help to maximize the efficiency of a thickened heart muscle and commonly include:
If medication alone isn’t enough to fully treat your condition, AHN provides dedicated care with our surgeon and interventional cardiologists who are experienced at performing procedures that can thin your heart’s walls. AHN electrophysiologists can also implant small devices called defibrillators (also known as ICDs) that monitor your heart’s rhythm and can immediately recognize and treat a life-threatening rhythm if one were to occur.
