Eligibility Criteria

Age 18+ · All Participants · 3 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
You have a heart condition called hypertrophic cardiomyopathy (HCM) which causes your heart muscle to thicken abnormally. This is diagnosed if your heart's left ventricular wall thickness is greater than or equal to 15 millimeters (mm) or greater than or equal to 13 mm if you have a family history of HCM, and there are no other known heart or systemic diseases causing the thickening. The diagnosis will be confirmed by a specialized laboratory.
Your heart's left ventricular outflow tract pressure gradient should be less than 30 mm Hg while at rest, and less than 50 mm Hg when undergoing certain tests to provoke a response from your heart.
You have heart problems that fall under Class II or III of the New York Heart Association (NYHA) classification.
