Deep learning-derived biological age from preoperative chest radiographs predicts mortality following surgical and transcatheter procedures for structural heart disease beyond EuroSCORE II

A chest X-ray analysis can estimate biological aging to better predict surgical risk beyond existing heart surgery scores.

A deep learning model extracted biological age from routine preoperative chest X-rays and demonstrated this metric adds independent mortality prediction power beyond the established EuroSCORE II cardiac surgical risk score. This positions CXR-based biological age as a non-invasive, universally available imaging biomarker for perioperative cardiac risk stratification.
