Objective:

To summarize evidence on nutritional adherence in cardiac rehabilitation for patients with coronary heart disease after PCI using mobile healthcare systems.

Approach:

• Evidence Summary Protocol: The study employed the PIPOST model to formulate evidence-based questions focusing on patients with coronary heart disease after PCI and interventions related to nutritional adherence using mobile healthcare systems.
• Search Strategy: A systematic search was conducted using the '5S' pyramid model, prioritizing high-level evidence from clinical decision support systems, evidence summaries, guidelines, and systematic reviews, supplemented by primary studies.
• Inclusion and Exclusion Criteria: Inclusion criteria focused on patients aged ≥18 years with coronary heart disease post-PCI, while exclusion criteria eliminated duplicate publications and literature that did not pass quality assessment.

Key Findings:

• Nutritional adherence post-PCI is often less than 32%.
• Mobile healthcare systems can enhance dietary behavior in cardiac rehabilitation.

Interpretation:

Improving nutritional adherence is crucial for reducing cardiovascular mortality among patients with coronary heart disease after PCI.

Limitations:

• Existing research on nutritional adherence in cardiac rehabilitation is limited and scattered.
• Challenges in dietary behavior change include complexity in dietary recording and social/cultural influences.

Conclusion:

The study aims to synthesize evidence on nutritional adherence management using mobile health technologies.
