Washington DC: Scientists have developed an artificial intelligence (AI) based system that can better predict heart attacks and other cardiac events as compared to conventional risk models. Risk determination is an imperfect science, and popular existing models like the Framingham Risk Score have limitations, as they do not directly consider the condition of the coronary arteries. Coronary computed tomography arteriography (CCTA), that gives highly detailed images of the heart vessels, is a promising tool for refining risk assessment, according to a study published in the journal Radiology.

While CAD-RADS is an important and useful development in the management of cardiac patients, its focus on stenoses may leave out important information about the arteries, said Kevin M Johnson, associate professor at the Yale School of Medicine in the US.
