INCENTIVE: Increasing Exercise Adherence After Percutaneous Coronary Intervention With the Fitbit Charge HR Device
Study Details
Study Description
Brief Summary
Design: Single center, prospective, randomized study that will compare activity levels in patients who complete cardiac rehabilitation after clinically indicated percutaneous coronary intervention with and without use of the wrist-worn Fitbit Charge HR device and mobile platform application.
Primary Endpoint: The average number of steps taken per day will serve as the main marker of daily physical activity.
Control: Patients who do not receive the device (Fitbit Charge HR).
Secondary Endpoints: (1) change in daily energy expenditure (2) change in number of activity and sedentary bouts (3) change in sleep efficiency (4) change in weekly time of moderate/vigorous physical activity (5) change in quality of life (6) change in indicators of depression (7) change in medication adherence(8) change in HDL and LDL cholesterol (9) change in BMI and waist circumference (10) change in resting heart rate and blood pressure (11) change in exercise stress test performance (timeframe for all: baseline - 12 weeks)

|---|---|
| Active Comparator: Fitbit Charge HR Use of the Fitbit Charge HR, a simple, user-friendly, wrist-worn, commercially available device which provides feedback on exercise goal adherence, in combination with the Fitbit mobile platform application. All patients will wear the Actigraph wGT3X-BT, from which data is extracted. Actigraph does not provide patient any feedback. |
Device: Fitbit Charge HR
Patients randomized to the FitBit group will receive Fitbit Charge HR, a simple, user-friendly, wrist-worn, commercially available device which provides feedback on exercise goal adherence, in combination with the Fitbit mobile platform application.

| No Intervention: No Device No Fitbit used and no feedback on exercise goal adherence. All patients will wear the Actigraph wGT3X-BT, from which data is extracted. Actigraph does not provide patient any feedback. |
Outcome Measures
Primary Outcome Measures
- Relative change in average number of steps taken per day [Baseline and 12 weeks after completion of cardiac rehabilitation]
Secondary Outcome Measures
- Relative change in average daily energy expenditure measured in % change in the average number of calories (kcal) expended per day [Baseline and 12 weeks after completion of cardiac rehabilitation]
Average daily energy expenditure will be measured in kcal/day by the Actigraph wGT3X-BT device.
- Relative change in average number of daily activity bouts measured in % change in the average number of activity bouts per day [Baseline and 12 weeks after completion of cardiac rehabilitation]
Activity bouts will be measured as periods of continuous activity recorded by the Actigraph wGT3X-BT device.
- Relative change in average number of daily sedentary bouts measured in % change in the average number of sedentary bouts per day [Baseline and 12 weeks after completion of cardiac rehabilitation]
Sedentary bouts will be measured as periods of prolonged inactivity recorded by the Actigraph wGT3X-BT device. Non-wear time periods are excluded from this analysis.
- Relative change in average daily sleep efficiency measured in % change in average sleep efficiency. Sleep efficiency will also be measured in %. [Baseline and 12 weeks after completion of cardiac rehabilitation]
Sleep efficiency will be measured in % using data from the Actigraph wGT3X-BT device.
- Relative change in average weekly moderate/vigorous physical activity, measured in % change in minutes spent in moderate/vigorous physical activity per week [Baseline and 12 weeks after completion of cardiac rehabilitation]
change in weekly time of moderate/vigorous physical activity (MVPA, defined as activity intensity of ≥3.0 metabolic equivalents [MET] or ≥100 steps/min) (minutes).
- Relative change in quality of life, measured in % change in SF-36 health survey questionnaire score [Baseline and 12 weeks after completion of cardiac rehabilitation]
change in quality of life (as assessed by the Short Form Health (SF36) questionnaire).
- Relative change in indicators of depression, measured in % change in PHQ9 questionnaire score [Baseline and 12 weeks after completion of cardiac rehabilitation]
change in indicators of depression (as assessed by the Patient Health (PHQ9) questionnaire).
- Relative change in medication adherence, measured in % change in MMAS questionnaire score [Baseline and 12 weeks after completion of cardiac rehabilitation]
change in medication adherence (as assessed by the Morisky Medication Adherence Scale (MMAS-8).
- Relative change in HDL and LDL cholesterol [Baseline and 12 weeks after completion of cardiac rehabilitation]
- Relative change in BMI [Baseline and 12 weeks after completion of cardiac rehabilitation]
- Relative change in resting heart rate [Baseline and 12 weeks after completion of cardiac rehabilitation]
- Relative change in exercise stress test performance [Baseline and 12 weeks after completion of cardiac rehabilitation]
- Relative change in blood pressure (BP) [Baseline and 12 weeks after completion of cardiac rehabilitation]
- Relative change in waist circumference [Baseline and 12 weeks after completion of cardiac rehabilitation]
