Smartwatch Photoplethysmography-Derived Heart Age via ECG-Guided Cross-Modal Pretraining as a Digital Biomarker of Vascular Aging

2026-08-05

Abstract excerpt

<title>Abstract</title> <p>Digital biomarkers of cardiovascular aging derived from physiological signals, commonly referred to as heart age or vascular age, have been extensively studied and shown to associate with a range of diseases and cardiovascular outcomes. However, most existing work relies on resting electrocardiography (ECG), imaging, or specialized clinical vascular function measurements, and studies th...
