- PPG Heart Age via ECG-Guided Cross-Modal Pretraining (arXiv:2608.01620)2026 · arXiv preprint
This study estimates heart age from smartwatch PPG, using synchronized smartwatch ECG to guide pretraining so that only PPG is needed in use. It draws on three OPPO cohorts in China with 581,804 participants and 7,452,131 recordings. The PPG-only model estimated age with errors of 5.9 years (r = 0.82) and 4.3 years (r = 0.80) in two external cohorts, and a larger heart-age gap was linked to higher pulse wave velocity.
