Clinical Report: Evaluation of a Digital Health Intervention Following PCI
Overview
This study evaluated the effectiveness of a multimodal digital health intervention (SK-121) in reducing recurrent cardiovascular events post-percutaneous coronary intervention (PCI). The intervention did not significantly lower the SMART2 risk score overall. However, it improved disease knowledge, medication adherence, and diastolic blood pressure in participants.
Background
Coronary artery disease (CAD) is a leading cause of mortality globally, with many risk factors being modifiable. There is a notable gap between clinical guidelines for CAD management and real-world implementation. Digital health technologies may offer solutions to enhance adherence to lifestyle changes for patients following PCI.

Key Findings
The digital health intervention did not significantly reduce the SMART2 risk score in the overall population.
Participants in the intervention group showed significant improvements in disease knowledge at both 6 and 12 months (P < 0.001).
Medication adherence was significantly higher in the intervention group at 6 months (P = 0.030).
Diastolic blood pressure was significantly lower in the intervention group at 12 months (−3.7 mmHg; P = 0.003).
In overweight participants, the intervention significantly reduced SMART2 scores at 12 months (−3.7%; P = 0.033).
Clinical Implications
The findings indicate that while the digital health intervention did not reduce cardiovascular risk scores broadly, it improved disease knowledge and medication adherence.
Conclusion
The multimodal digital health intervention demonstrated positive effects on knowledge and adherence but did not achieve the primary endpoint of reducing cardiovascular risk scores in the overall cohort.

In a multicenter registry study, genetic diagnoses were associated with substantially lower cognitive, language, and motor scores; while birth weight, surgical timing, hospitalization burden, and caregiver education were also associated with outcomes.
