A 12-week smartphone app-based exercise tutoring program with wearable heart rate monitoring was feasible in stable CHD patients, achieving a 90.3% completion rate and improving peak VO2 (P=0.041).
Does a smartphone app for prescribed exercise tutoring combined with wearable heart rate monitoring improve exercise compliance and clinical outcomes in patients with stable coronary heart disease?
A 12-week remote digital cardiac rehabilitation program using a smartphone app and wearable heart rate monitor is feasible and improves cardiorespiratory endurance, LDL, and psychological well-being in patients with stable CHD.
Background Digital health technologies have potential to address the challenges associated with traditional cardiac rehabilitation (CR). However, it is not complete enough for prescribed exercise guidance and remote monitoring. Objective We aimed to evaluate the feasibility of a smartphone app for prescribed exercise tutoring by exercise videos combined with wearable devices to monitor heart rate in patients with stable coronary heart disease (CHD). Methods The study is a quasi-experimental design study with a single group. A total of 31 patients were included with an average age of 56.2 years (SD 13.4). They participated in a 12-week remote digital CR program. We employed a wearable heart rate monitoring device connected with an app to monitor the patients’ exercise intensity. The app can display the videos corresponding to an exercise prescription to guide the exercise. Cardiorespiratory endurance, blood pressure, blood glucose, cholesterol, blood uric acid, left ventricular ejection fraction and quality of life (QoL) were assessed at the beginning and end of the intervention. Compliance and safety events were recorded as well. Results Completion rate reached 90.3%. Average daily effective exercise time was 39.4 min (SD 17.8), and 92.9% of the patients could exercise in the prescribed intensity for at least 20 min per day. Average effective exercise days per week were 4.6 days (SD 2.2), and 67.9% of the patients could exercise in the prescribed intensity for at least 3 days per week. Patients’ peak VO 2 ( P = 0.041) and peak metabolic equivalents ( P = 0.018) were significantly increased, low-density lipoprotein ( P = 0.036) and diastolic blood pressure at rest ( P = 0.044) were significantly decreased, and depression (GAD-7, P = 0.014) and anxiety (PHQ-9, P = 0.013) were significantly improved. Conclusions It is feasible, safe, and helpful for stable CHD patients to use the app for prescribed exercise tutoring with videos combined with wearable devices to monitor heart rate.

Xia et al. (Sun,) conducted a other in stable coronary heart disease (CHD) (n=31). Smartphone app for prescribed exercise tutoring with wearable heart rate monitoring was evaluated on Feasibility (completion rate). A 12-week smartphone app-based exercise tutoring program with wearable heart rate monitoring was feasible in stable CHD patients, achieving a 90.3% completion rate and improving peak VO2 (P=0.041).
