A team of clinicians and scientists from Tempus and Geisinger found that a new artificial intelligence model can accurately identify patients at increased risk of undiagnosed structural heart disease. Structural heart disease (SHD) is a group of conditions that adversely affect the heart's valves, walls, chambers, or muscles. The Tempus and Geisinger study sought to address this diagnostic gap by developing a novel machine learning model that uses data from a 12-lead electrocardiogram to identify patients at elevated risk of undiagnosed SHD. Published in Circulation (DOI:10.1161/CIRCULATIONAHA.121.057869), the rECHOmmend model can predict any one of seven structural heart diseases diagnosable by an ultrasound of the heart. Overall, the study found that the model achieved excellent performance, exceeding the performance of any previously published model predicting any single disease.
