Abstract
Hypertrophic cardiomyopathy (HCM), characterized by left ventricular hypertrophy in the absence of causative loading conditions, is one of the most common inheritable cardiac diseases. Mild phenotypic expression of HCM can overlap with some of the physiological adaptive changes seen in the athlete’s heart and can present a diagnostic challenge.
HCM has been strongly associated with sudden cardiac death in athletes. As a result, individuals with HCM have traditionally been excluded from participation in most sporting endeavors. Recent data, however, highlight the risks of a sedentary lifestyle and the benefits of exercise in those with HCM. Recognizing the importance of patient-centered care and the heterogeneity of the disease expression and outcomes in HCM, decisions regarding competitive sporting participation are evolving in lower-risk individuals to an individualized shared decision-making process. This chapter explores these issues to provide a diagnostic and management framework for practitioners involved in the care of athletes with HCM.
