Heart failure is among medicine's quieter crises — millions carry it without knowing, and the tools to catch it early have long been out of reach for many. Researchers at Wake Forest University School of Medicine have trained an artificial intelligence model on more than a million electrocardiograms, teaching it to recognize three distinct forms of heart dysfunction — including the notoriously elusive preserved ejection fraction type — from a test already present in nearly every clinical setting. The model works nearly as well from a single electrical lead, the kind a smartwatch can capture, s

AI-powered ECG analysis enables early detection of multiple heart failure types, potentially reducing diagnostic costs and expanding screening accessibility through wearable integration.
Consumers benefit from lower-cost, more accessible heart failure screening via routine ECGs and potentially wearables, reducing need for expensive echocardiograms and enabling earlier intervention, which improves health outcomes and reduces hospitalization costs.
FDA may need to establish regulatory pathways for AI-assisted diagnostic tools; CMS could expand reimbursement for AI-enhanced ECG analysis; healthcare systems may shift diagnostic protocols; data privacy regulations (HIPAA) require attention for wearable integration.
