Key result
A smartphone-based cardiac rehabilitation application significantly reduced total cholesterol, LDL, and anxiety, and improved exercise capacity and quality of life in post-PCI patients (P<0.05).
Why the study?
Cardiac rehabilitation is underused worldwide, especially in Asian regions, prompting evaluation of a mobile health application to support self-care and improve phase II cardiac rehabilitation effects after PCI in Macao.
Does a smartphone-based mobile health application improve cardiac rehabilitation outcomes in patients post percutaneous coronary intervention?
RCT (n=140)
No
Does a smartphone-based mobile health application improve cardiac rehabilitation outcomes in patients post percutaneous coronary intervention?
p-value: p=<.05
A smartphone-based mobile health application is feasible and effective in improving clinical, psychological, and functional outcomes during phase II cardiac rehabilitation post-PCI.
Supports mHealth CR app feasibility in Macao post-PCI patients; leaves open efficacy and scalability for larger trials.
BACKGROUND: Cardiac rehabilitation (CR) referral and participation are generally found to be underused worldwide. The data in Asian regions suggest significant underutilization compared with western countries. OBJECTIVES: To promote the continuity and effects of CR, this study aimed at supporting self-care and improving CR effects in phase II CR with mobile health application for Macao patients who have undergone percutaneous coronary intervention. METHODS: The study was a randomized controlled trial conducted between January 2018 and June 2020 in a nongovernmental Hospital. Social cognitive theory was applied in the intervention for an experimental group. Measurements including anxiety and depression level, medication adherence, exercise capacity, physical activity level, cardiovascular risk modification, self-efficacy, quality of life, use of healthcare resources, mHealth CR utility, and satisfaction were analyzed. RESULTS: One hundred forty eligible patients were recruited, and 110 patients completed the study. Significant interventional effects of the experimental group were found on the reduction of total cholesterol, low-density lipoprotein, sitting time, anxiety level, and total anxiety and depression level ( P < .05). In addition, significant improvement on the 6-minute walk test, regular exercise performance, self-efficacy of cardiac exercise and diet, and quality of life were found as interventional effects in the experimental group ( P < .05). The feasibility of intervention was achieved in a satisfactory level. CONCLUSIONS: This theoretically grounded mobile health CR study was a unique program tailor-made to meet the care needs of patients post percutaneous coronary intervention. It was feasible and effective to support CR effects and adherence and would inform further design of clinical practice and public policies.

Lao et al. (2023) conducted an RCT in Post percutaneous coronary intervention (n=140). Smartphone-based mobile health application for cardiac rehabilitation vs. Control group was evaluated on Anxiety and depression level, medication adherence, exercise capacity, physical activity level, cardiovascular risk modification, self-efficacy, quality of life, use of healthcare resources, mHealth CR utility, and satisfaction (p=<.05). A smartphone-based cardiac rehabilitation application significantly reduced total cholesterol, LDL, and anxiety, and improved exercise capacity and quality of life in post-PCI patients (P<0.05).
