Foundation Model for Post-MI Cardiovascular Event Alert Using Huawei Watch
1,050 participantsStarted 2026-04-01
Plain-language summary
The goal of this randomized controlled trial is to evaluate whether a HUAWEI smartwatch integrated with a foundation model can enhance daily monitoring and management of AMI patients during outpatient cardiac rehabilitation after PCI.
Can a HUAWEI smartwatch with a foundation model improve daily monitoring/management of post-PCI AMI patients during 3-month outpatient CR, vs routine management or smartwatch without AI? Does the AI-enabled smartwatch (Intervention I) reduce 3-month cardiovascular-related hospital/emergency visits vs the other two groups? Do smartwatches (with/without AI) enhance quality of life and activity function post 3-month CR? Does the AI-enabled smartwatch lower 1-year major adverse cardiovascular events (MACEs) and related hospital/emergency visits vs other groups? How accurate is the AI-enabled smartwatch's alert system (vs hospital diagnostic results) for cardiovascular abnormalities? What is the usability of the AI-enabled smartwatch for patients and doctors?
Participants will:
Sign informed consent; complete baseline exams (MET, SF-36, 6-minute walk, exercise tolerance test) and questionnaires (demographics, medical history, medications).
Receive 3-month outpatient CR. Attend follow-ups; report all adverse events promptly.
Intervention I (AI-Enabled Smartwatch) group Wear the smartwatch continuously for 3 months (sleep wear recommended); actively collect ≥30s ECG via the watch's crown.
Pause activity if heart rate exceeds anaerobic threshold; adjust exercise intensity if METs mismatch prescription.
Contact doctors immediately upon receiving abnormality alerts (e.g., heart failure); follow expert recommendations for further care; complete usability questionnaires.
Intervention II (Non-AI Smartwatch) group Wear the smartwatch continuously for 3 months (sleep wear recommended) to track activity/sleep, monitor real-time heart rate/MET.
Pause activity if heart rate exceeds anaerobic threshold; adjust exercise intensity if METs mismatch prescription.
Control Group Complete routine outpatient CR and follow-ups (no smartwatch use).
