Brief Summary:
The long term health and cardiovascular benefits of a regular exercise program have been well-established. National guidelines recommend involvement in moderate aerobic fitness (i.e. walking, bicycling, light jogging, swimming) for patients with hypertrophic cardiomyopathy (HCM). However, data on potential benefits of recreational exercise, useful parameters for risk stratification, and methods of devising individual exercise prescriptions are completely lacking. The specific aims of this study are: 1) to devise a safe moderate intensity exercise training program in patients with HCM, and 2) to determine whether exercise training improves ability to perform activities and tasks, heart size and function, and quality of life in patients with HCM.

Condition or disease Intervention/treatment
Cardiomyopathy, Hypertrophic Behavioral: stop exercising
