Sustaining Physical Activity Following Cardiac Rehabilitation Completion

Study Overview
=================
Brief Summary
-----------------
Cardiac rehabilitation participants will be enrolled during cardiac rehabilitation and provided an activity tracker to use.

Detailed Description
-----------------
Cardiac rehabilitation participants will be enrolled during cardiac rehabilitation and provided an activity tracker to use. Each week they will be provided a summary report of their steps and physical activity, that will continue to 6 weeks post discharge from cardiac rehabilitation.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average Steps Per Day (Preintervention Period) | Average steps per day measured by the activity tracker | pre-intervention (during cardiac rehab starting on the day the tracker was given to cardiac rehab discharge), a total of up to 10 weeks | 
| Average Physical Activity in Minutes Per Day (Preintervention Period) | Average very active minutes per day of physical activity measured by the activity tracker | pre-intervention (during cardiac rehab starting on the day the tracker was given to cardiac rehab discharge), a total of up to 10 weeks | 
| Average Steps Per Day (Intervention Period) | Average steps per day measured by the activity tracker | Intervention (day following cardiac rehab discharge to the day the last weekly report was sent), a total of up to 10 weeks | 
| Average Physical Activity in Minutes Per Day (Intervention Period) | Average very active minutes per day of physical activity measured by the activity tracker | Intervention (day following cardiac rehab discharge to the day the last weekly report was sent), a total of up to 10 weeks | 
| Average Steps Per Day (Maintenance Period) | Average steps per day measured by the activity tracker | Maintenance (day following when the last weekly report was sent to last day of tracking by staff), a total of up to 15 weeks | 
| Average Physical Activity Per Day (Maintenance Period) | Average very active minutes per day of physical activity measured by the activity tracker | Maintenance (day following when the last weekly report was sent to last day of tracking by staff), an overall total of up to 15 weeks |
