At NYU Langone’s Hypertrophic Cardiomyopathy Program, our cardiologists and heart surgeons have more than 25 years of experience treating people with hypertrophic cardiomyopathy, also known as HCM.

NYU Langone is one of only a handful of institutions in the United States to offer comprehensive management of hypertrophic cardiomyopathy. Ours is one of two programs in New York State to be accredited by the Hypertrophic Cardiomyopathy Association as a Center of Excellence. We are widely recognized for our commitment to patients and success in providing the highest quality specialized healthcare.

Hypertrophic cardiomyopathy is a heart condition caused by a thickening of the heart muscle. Symptoms include shortness of breath, chest pressure, blackouts, and lightheadedness. In some people, the heart becomes stiff and cannot fill properly. In others, the flow of blood out of the heart is obstructed.

Because of these abnormalities, the heart cannot pump enough blood to the rest of the body. This is especially true during exercise. Hypertrophic cardiomyopathy can be associated with irregular heart rhythms that in some people can be dangerous.

Our team includes a cardiologist who discusses diagnosis and treatment options with you in detail, a surgeon who is an expert and innovator in the repair of hypertrophic cardiomyopathy, specialists from the Heart Rhythm Center who diagnose heart rhythm irregularities, and experts in the insertion and management of devices that correct heart rhythm.

We also offer genetic screening, DNA analysis, and counseling for family members of people with hypertrophic cardiomyopathy. Such information can reveal which members of your family might have inherited a predisposition to the condition.
