Tech breakthrough offers an early warning system for heart attacks

Oct. 5, 2018

A new method of analyzing images from CT scans can predict which patients are at risk of a heart attack years before it occurs, researchers say.

The technology, developed by teams at Oxford University and institutions in Germany and the U.S., uses algorithms to examine the fat surrounding coronary arteries as it shows up on computed tomography (CT) heart scans.

That fat gets altered when an artery becomes inflamed, serving as an early warning system for what one of the researchers believes could be up 30% of heart attacks.

Most heart attacks are caused by a build-up of plaque—a fatty deposit—inside the artery, which interrupts the flow of blood.

Currently, CT scans tell a doctor when an artery has already become narrowed by plaque.

With the new technology, for which the researchers hope to gain regulatory approval on both sides of the Atlantic within a year, doctors will be able to say which arteries are at risk of narrowing.

Heart disease and stroke are the two biggest causes of death worldwide.

An Oxford University spin-off company is now developing a service to analyze CT scans from across the globe in around 24 hours.

The research was published in late August in medical journal The Lancet.
