Early Research Suggests Promising Use of AI to Predict Risk of Heart Attack or Stroke Using a Single Chest X-Ray
by CNN Health
Preliminary findings presented at the recent annual meeting of the Radiological Society of North America suggests artificial intelligence (AI) could be used to predict the 10-year risk of death from a heart attack or stroke from just one chest X-ray. Researchers trained an AI program on nearly 150,000 chest X-rays to find patterns in the images associated with risk from major cardiovascular disease events. By testing the algorithm on a separate cohort of 11,000 people, they found a “significant association” between the risk level forecast by the AI and the actual incidence of a major cardiovascular disease event. Statin therapy is recommended for people with a 10-year risk of 7.5 percent or above, and the AI model applies the same risk thresholds as the established risk calculator. “This is exactly the kind of application that AI is best for,” said Donald Lloyd-Jones at Northwestern University's Feinberg School of Medicine. “So we need to continue to do things like this to really understand if we can find, particularly, patients who would otherwise slip through the cracks.”
