High Intensity Exercise for Increasing Fitness in Patients With Hypertrophic Cardiomyopathy – Full Text View

Regular exercise reduces the risk of all-cause and cardiovascular mortality in the general population. Specifically, higher cardiorespiratory fitness is associated with a 10 – 20 % reduction in mortality risk for every 1 MET (metabolic equivalent tasks) improvement in fitness. A high degree of fitness is also protective against the development of heart failure and exercise training has become the standard of care for most patients with cardiovascular disease to improve functional capacity, and reduce morbidity and mortality. However, hypertrophic cardiomyopathy, the most common inherited cardiovascular disease, may be an exception. For more than 30 years, hypertrophic cardiomyopathy (HCM) has been identified as the most common cause of death in young athletes, and patients with HCM are excluded from participation in competitive sports. The fear of provocation of sudden cardiac death has often been extended to non-competitive athletic activities in such patients, though there is a distinct lack of evidence
