Discovery of the day
A transformer-based artificial intelligence ECG model trained exclusively on 341,151 publicly available electrocardiograms demonstrated accurate prediction of 30-day and 1-year mortality following transcatheter aortic valve replacement. In a prospective cohort of 439 TAVR patients, a single pre-procedural ECG yielded an AUC of 0.85 for 30-day mortality and 0.74 for 1-year mortality, with the derived AI-ECG risk score independently associated with 1-year mortality (adjusted OR 1.70). This finding is directly relevant to clinical practice as it provides a transparent, shareable, and generalisable tool for pre-procedural risk stratification, enabling clinicians to identify high-risk patients and guide acute care decision-making in a real-world setting.
