AI-PPG Age: A Novel Digital Biomarker
The study introduces Artificial Intelligence-derived Photoplethysmography (AI-PPG) age, a novel deep learning-based estimate of biological age from raw PPG signals. Unlike traditional methods, AI-PPG age is derived non-invasively from widely available wearable sensors, making it ideal for large-scale, population-level screening. A higher AI-PPG age gap (AI-PPG age minus calendar age) signifies accelerated vascular aging and is strongly associated with increased risk of major adverse cardiovascular and cerebrovascular events (MACCE), as well as specific outcomes like coronary heart disease, myocardial infarction, stroke, and all-cause mortality. This provides a clear, intuitive metric for individuals to understand their cardiovascular health status.

Case Study: MIMIC-III External Validation
The AI-PPG age gap was rigorously validated using the independent MIMIC-III-derived cohort, comprising 2,343 critical ill patients. This external validation demonstrated a significant association between an overestimated AI-PPG age gap and increased in-hospital mortality. Specifically, each one-year increase in AI-PPG age gap was associated with an odds ratio of 1.02 (p = 0.01) for higher in-hospital mortality. This finding underscores the model's generalizability and its potential clinical utility for risk stratification in diverse and high-risk patient populations, extending beyond general population screening to critical care settings where timely assessment is crucial.
