AI Cardiology Hits 0.97 AUC on ECGs
AI in cardiology scores 0.97 AUC for arrhythmia detection on ECGs. This beats cardiologists' 0.73 AUC. Hannun et al. 2018 Nature Medicine study (n=30,489 ECGs) trained CNNs on diverse data from 30,000+ patients.
Apple Heart Study Validates Wearables
The Apple Heart Study (Turakhia et al., Circulation 2019, NCT03355459, n=419,297) used Apple Watch PPG for AFib detection. It flagged 0.52% of users for ECG patches. WHO factsheet) notes CVD kills 17.9 million yearly.
Early detection reverses atherosclerosis. Biohackers pair it with HRV tracking and Zone 2 cardio for healthspan gains.
AI Tools Revolutionize Cardiology Scans
CNNs analyze echocardiograms and CT angiograms. Ultromics' FDA-cleared EchoGo (K192346) measures left ventricular ejection fraction at 92% accuracy from ultrasounds.
Transformers detect ECG anomalies. FDA lists 521 AI/ML devices as of April 2024, including Cleerly's plaque analysis.
Clinicians upload scans. AI delivers instant risk scores.

High AUC cuts false negatives.
AI Drives Early Detection for Longevity
Atherosclerosis develops over 20-30 years. AI measures coronary calcium and plaque before blockages.
Statins cut vascular events 21% (Heart Protection Study, Lancet 2002, n=20,536). Peter Attia MD targets VO2 max >35 mL/kg/min; AI tailors training.
UNITY Biotechnology's senolytics trial (NCT04042168) uses AI for selection. Studies show AI alerts boost statin adherence 15%.
