New AI tool can detect heart failure up to 5 years in advance

A new AI tool developed by Oxford researchers predicts heart failure risk up to five years in advance using routine cardiac CT scans, analysing hidden heart fat with 86% accuracy. Trained on over 70,000 NHS patients, it identifies high-risk individuals (1-in-4 chance within five years) 20 times more likely than low-risk ones, enabling early prevention.
