Oxford AI flags five-year heart failure risk from routine CT scans

Oxford researchers have created an AI tool that analyzes fat around the heart on routine cardiac CT scans to predict five-year heart‑failure risk with about 86% accuracy; trained on 72,000 patients across nine NHS trusts and followed for a decade, the model outputs an absolute risk score to guide monitoring and treatment, with those at highest risk up to 20 times more likely to develop heart failure within five years.
