AI improves detection of dangerous plaques linked to heart risk

The study linked AI-detected plaques to higher chances of repeat heart attacks and deaths.
AI analysis of artery scans predicts heart risk more accurately than manual review.

Researchers have shown that AI can analyse coronary scans after a heart attack and predict future risks better than traditional review. The findings come from the PECTUS-AI study, published in the European Heart Journal.

Using optical coherence tomography, the AI algorithm identified vulnerable plaques across entire artery segments.

Patients with these thin-cap fibroatheromas were found to have significantly higher rates of death, repeat heart attacks or unplanned procedures over two years.

Manual frame-by-frame review by specialists remains time-consuming and inconsistent, while AI delivers a faster and more standardised assessment.

Researchers say further validation is needed before routine adoption, but the technology could play an important role in secondary prevention.
