Effects of an eHealth Cardiac Exercise Rehabilitation Platform for Patients After Percutaneous Coronary Intervention Based on the Persuasive Systems Design Model: Randomized Controlled Trial

Q: What are the key findings of this study?

An eHealth cardiac exercise rehabilitation platform significantly increased physical activity levels by 937.29 MET-minutes/week compared to standard care in patients after percutaneous coronary intervention.

Q: What is the clinical evidence from this study?

Study design: RCT. Population: Coronary Heart Disease. Intervention: eHealth Cardiac Exercise Rehabilitation Platform vs. Standard care (in-hospital education, exercise guidance, and follow-up support). Primary outcome: Physical activity level (Metabolic Equivalent Task minutes per week) (β coefficient 937.29, 95% CI 867.61-1006.97, p=<.001).

Key result

eHealth CR boosts post-PCI physical activity ~114% and improves quality of life vs standard care.

β coefficient 937.29
95% CI 867.61-1006.97
P<.001

Why the study?

Participation and compliance with cardiac exercise rehabilitation after PCI remain suboptimal, and remote rehabilitation via mobile health technology can help overcome traditional rehabilitation barriers.

Does an eHealth cardiac rehabilitation platform added to standard care improve physical activity levels in patients with coronary heart disease after percutaneous coronary intervention?

Implication

Supports eHealth cardiac rehabilitation post-PCI; strengthens RCT evidence for digital platforms in coronary disease.

Key Points

To evaluate the effects of an eHealth cardiac rehabilitation platform based on the persuasive systems design model, added to standard care, on physical activity, endurance, fatigue, self-efficacy, and quality of life after percutaneous coronary intervention.
Single-blinded, parallel randomized controlled trial conducted at a tertiary hospital in Hangzhou, China, enrolling 180 eligible patients with coronary heart disease (1:1 allocation to intervention or control, n=90 per group).
Participants engaged in a 24-week eHealth cardiac rehabilitation program, with assessments at baseline (T0), 12 weeks of intervention (T1), and follow-up at 4 (T2), 8 (T3), and 12 (T4) weeks analyzed via generalized estimating equation models.
Generalized estimating equation analyses revealed significant group-by-time interactions across all measured outcomes (all P<.001).
At 12 weeks of follow-up (T4), the intervention group achieved higher physical activity (median 1723.00 vs 805.50 Metabolic Equivalent Task minutes per week; β=937.29, 95% CI 867.61-1006.97, P<.001) and greater 6-minute walk distance (median 436.00 vs 405.00 m; β=31.00, P<.001).
The intervention arm also displayed reduced fatigue (median 9.00 vs 10.00; β=–1.00, P<.001; no difference at T1 with P=.50), higher exercise self-efficacy (61.11 vs 27.78; β=33.33, P<.001), and higher SF-36 scores (91.19 vs 84.13; β=7.06, P<.001) at T4.

Intervention

24-week eHealth cardiac rehabilitation (CR) program based on the persuasive systems design model (delivered via WeChat) in addition to standard CR

Comparator

Standard cardiac rehabilitation (in-hospital education, exercise guidance, and follow-up support)

Outcome

Physical activity (PA) level measured in Metabolic Equivalent Task (MET) minutes per week at 24 weeks (T4)patient reported

Main Result

Mean Difference: 937.29 (95% CI 867.61–1006.97)

Absolute Event Rate: 1723% vs 805.5%

p-value: p=<.001

An eHealth cardiac rehabilitation platform based on the persuasive systems design model significantly improved physical activity, exercise endurance, and quality of life in patients after PCI.
