Vigorous exercise and sports participation in individuals with hypertrophic cardiomyopathy.

Historically, individuals with HCM have been restricted from vigorous competitive sports due to concerns for risk of sudden death. More recently, prospective data are emerging that individuals with HCM who participate in vigorous sports do not have increased arrhythmic risk compared to the less active, and series of athletes with HCM continuing to compete, while small, have not shown high risk. Guidelines are evolving, and while differences exist, all now recommend an individualized approach and shared decision-making for athletes with HCM wishing to return to play.
