PURPOSE: To assess the feasibility of a technology-assisted intervention in a hybrid cardiac rehabilitation program among patients with coronary heart disease. METHODS: This study was a two-armed parallel randomized controlled trial. Twenty-eight patients with coronary heart disease were randomly assigned to either the intervention group, receiving a 12-week technology-assisted intervention (n = 14) or the control group (n = 14), receiving usual care. Guided by the Health Belief Model, the intervention group received three center-based, supervised exercise training sessions, a fitness watch that served as a cue to action, six educational videos and a weekly video call. The Self- Efficacy for Exercise, exercise capacity and Health Promoting Lifestyle Profile II were assessed at baseline and immediately post intervention (12-week). RESULTS: Amongst 28 patients who participated in this study, 85.7% completed the program with a relatively low attrition rate (14.3%). The number of exercise training sessions accomplished by the participants in the intervention group was 51.27 +/- 19.41 out of 60 sessions (85.5%) compared to 36.46 +/- 23.05 (60.8%) in the control group. No cardiac adverse events and hospitalization were reported throughout the study. Participants in the intervention group showed greater improvement in health promoting behavior when compared with control group at 12 weeks. Within group effects demonstrated improvement in exercise self-efficacy and exercise capacity among participants in the intervention group. A participant satisfaction survey conducted immediately post intervention revealed that participants were "very satisfied" (23.1%) and "satisfied" (76.9%) with the technology-assisted intervention. CONCLUSIONS: The findings demonstrated that technology-assisted intervention in a hybrid cardiac rehabilitation program was feasible and suggested to be beneficial in improving the exercise self-efficacy, exercise capacity and health promoting behavior among patients with coronary heart disease. A full-scale study is needed to determine its effectiveness in a long term. TRIAL AND PROTOCOL REGISTRATION: ClinicalTrials.gov NCT04862351https://clinicaltrials.gov/ct2/show/NCT04862351.
