  Fig. 1. Kaplan–Meier analysis of adverse event rates. The Kaplan–Meier curves for adverse clinical events comparing the Digital Management group and the Conventional Management group, including all-cause death (a), MACCE (b), cardiovascular death (c), myocardial infarction (d), recurrent angina (e) revascularization (f), stroke (g), and heart failure (h). The red line is the Digital Management group, and the green line is the Conventional Management group. * MACCE composite endpoint event of all-cause death, myocardial infarction, revascularization, and stroke.

  Fig. 2. Subgroup analyses of MACCE events. Subgroup analyses of digital management efficacy in MACCE events, stratified by sex, age, and ACS status, are presented. * MACCE composite endpoint event of all-cause death, myocardial infarction, revascularization, and stroke; ACS acute coronary syndrome.

  Fig. 3. Operating diagram of heartmed medical digital management system. “Heartmed medical digital management system” integrates smartphones, wearable devices, and medical data platforms to achieve secondary prevention of coronary heart disease. Through bidirectional data transmission between participants and caregivers, the system facilitates the transmission of educational knowledge, real-time assessment of risk factors, personalized reminders for lifestyle changes and rehabilitation exercises, recording of medication usage, and reminders for follow-up appointments. The system simultaneously adjusts the health management status based on the risk stratification and providing personalized disease management plans. *CAD coronary artery disease, GDMT guideline-directed medical therapy; LDL low-density lipoprotein.
