MyDigiTwin: A Privacy-Preserving Framework for Personalized Cardiovascular Risk Prediction and Scenario Exploration
This addresses the need for scalable, privacy-preserving personalized care in cardiovascular health, though it appears incremental as it builds on existing federated learning and digital twin concepts.
The paper tackles the problem of personalized cardiovascular disease prevention by introducing MyDigiTwin, a framework that integrates health digital twins with federated learning to train predictive models without transferring raw data, and demonstrates its feasibility through a proof-of-concept for CVD prediction.
Cardiovascular disease (CVD) remains a leading cause of death, and primary prevention through personalized interventions is crucial. This paper introduces MyDigiTwin, a framework that integrates health digital twins with personal health environments to empower patients in exploring personalized health scenarios while ensuring data privacy. MyDigiTwin uses federated learning to train predictive models across distributed datasets without transferring raw data, and a novel data harmonization framework addresses semantic and format inconsistencies in health data. A proof-of-concept demonstrates the feasibility of harmonizing and using cohort data to train privacy-preserving CVD prediction models. This framework offers a scalable solution for proactive, personalized cardiovascular care and sets the stage for future applications in real-world healthcare settings.
