Hypertrophic Cardiomyopathy

Abstract

Hypertrophic cardiomyopathy (HCM) is a condition characterized by a nondilated and hypertrophied left ventricle (LV), in the absence of a physiologic derangement that may account for the observed increased wall thickness. Data from exercise testing has an important role in the assessment and risk stratification of these patients. An abnormal blood pressure response to exercise, provocable left ventricular outflow tract gradient, or the detection of exercise-induced arrhythmias has important clinical implications. Cardiopulmonary exercise test data can also influence decisions regarding referral for heart transplantation.
