Key result
Multi-modal wearable system integrates machine learning and explainable AI to generate continuous cardiovascular risk scores.
Why the study?
Heart conditions often worsen before symptoms appear, and current wearable pipelines rely on single signals and coarse normal versus abnormal labels that arrive too late for prevention.
A proposed multi-modal wearable pipeline using machine learning and explainable AI aims to shift cardiovascular monitoring from reactive to personalized, continuous risk prediction.
Supports feasibility of multi-modal ECG-PPG wearables for early detection; leaves open whether it improves outcomes in prospective trials.
Heart and circulatory conditions remain a leading cause of death globally, and they often worsen quietly before obvious symptoms appear. Consumer wearables now make it practical to collect physiology around the clock, yet many pipelines still lean on one signal at a time and collapse decisions into coarse “normal vs abnormal” labels that arrive late for prevention. This work outlines a personalized, multi-modal wearable pipeline that jointly uses ECG, photoplethysmography (PPG), heart-rate variability (HRV), blood-oxygen saturation (SpO₂), and sleep-related cues. Machine learning sits on top of adaptive baselines so the model can learn what is typical for a given person, not only population averages, and it emits a continuous risk score from 0 to 100 that is easier to track over days and weeks. Explainable AI (XAI) is folded in so users and clinicians can see which factors moved the score, supporting trust and safer follow-up. Overall, the aim is to shift monitoring from reactive firefighting toward earlier, individualized cardiovascular vigilance.
