- Aims to broaden heart-failure screening via inexpensive, everyday ECG + AI
- Peerbridge Health, 2024–2027, recruiting
Peerbridge Health's trial (NCT06699056) validates the accuracy of medical AI software that estimates the heart's pumping metric, ejection fraction (EF), from a wearable ECG.
Per the registry summary, this is a prospective, multicenter, cluster-randomized controlled study of an investigational AI Software-as-a-Medical-Device (SaMD). The AI analyzes continuous ECG waveform data from the FDA-cleared "Peerbridge COR ECG Wearable Monitor" (an ambulatory patch worn during daily activities) to compute EF severity on the American Society of Echocardiography's 4-category scale. EF severity is determined from a 5-minute ECG recording taken during a 15-minute seated rest, and compared against EF severity from an FDA-cleared non-contrast transthoracic echocardiogram (TTE) predicate. Target enrollment is 2,000; November 2024 – November 2027; recruiting.
EF indicates how well the heart pumps blood and is used to diagnose and classify heart failure. It is usually assessed via echocardiography or cardiac MRI, which require specialized equipment and operators. Estimating severity from an inexpensive, everyday wearable ECG plus AI could broaden early detection and screening for heart failure.
Why it matters
Wearable-plus-AI cardiac screening is a widely watched area. Validating AI as a medical device (SaMD) against an established gold standard (echocardiography) is a useful example for the regulation and deployment of medical AI.
