🧪 AI Research of the Week

AI Prediction of Heart Failure Risk from Routine Cardiac CT Scans
University of Oxford

Jake’s Take: There's a little pocket of fat sitting around your heart, and that fat quietly changes texture when your heart muscle is starting to struggle. Years before you'd feel anything. Years before a doctor would catch it. Your eyes can't see the change on a scan.

The Oxford team built an AI that can. They trained it on CT scans from about 59k people in England, then tested it on another 13k or so. It correctly flagged future heart failure about 86% of the time, five years before the condition showed up. People it tagged as high-risk were 20 times more likely to get sick than the low-risk group.

What makes this more impressive is that nobody needs a new test; these are scans hospitals already do for chest pain or other reasons. The AI model just reads the pictures sitting in the system and spots something humans can't. Heart failure usually gets diagnosed late, once the muscle is already damaged. Catching it five years out changes what's possible. The team is now working to make it read any chest CT, not just heart-specific ones.
