AI tool maps three recovery paths for heart attack survivors

Researchers from the University of Surrey have identified three distinct health trajectories that heart attack survivors follow over five years, using an AI tool that could enable earlier, tailored care. The study, published in the Journal of the American Medical Informatics Association, analyzed health records of 12,701 UK Biobank participants. It found 63 percent developed cardiometabolic conditions, 23 percent suffered organ decline linked to smoking, and 14 percent developed structural heart issues. The smoking-related group had a 44 percent mortality rate, over three times higher than the largest group. Genetic analysis confirmed each trajectory mapped to distinct molecular pathways, with researchers noting the AI tool could predict outcomes at the event itself.
