A Study to Objectively Measure Physical Activity and Sedentary Behavior During Cardiac Rehabilitation

Participants enrolled in either home-based or center-based cardiac rehabilitation will be instructed to wear an accelerometer device for 7-days at baseline, 4-weeks, 8-weeks, and 12-weeks, to objectively measure their physical activity level during the cardiac rehabilitation program. A questionnaire will also be completed by the participant at baseline and 12-weeks to subjectively measure their physical activity level, based on self-report activities over the previous 7-days. Enrollment in home-based versus center-based cardiac rehabilitation will be based on the availability of cardiac rehabilitation facilities and/or patient preference. There is no random allocation or assignment to groups by the study team.
