New AI Model Can Predict Heart Attacks Years in Advance

A new artificial intelligence tool can predict the risk of a heart attack up to five years before it happens, according to a study published Tuesday. The system analyzes routine CT scans to detect hidden inflammation in arteries, a key warning sign that doctors often miss. Researchers developed the AI by training it on thousands of scan images. The technology identifies subtle patterns of plaque buildup and artery wall changes that are invisible to the human eye. In tests, the AI correctly flagged 80% of patients who later suffered a heart attack. Doctors say the tool could transform preventative care. Currently, many patients learn about their heart disease risk only after a major event. The AI allows for early intervention, such as prescribing statins or recommending lifestyle changes. The study’s lead author stated that the system is ready for clinical use pending regulatory approval. “This gives us a window to act before the damage is done,” he said. The team plans to offer the software to hospitals within two years.
