Technology that identifies people at risk of a heart attack in the next 10 years has been hailed as "game changing" by scientists.
The artificial intelligence (AI) model detects inflammation in the heart that does not show up on CT scans, which involve a combination of X-rays and computer technology.
A pilot project, supported by NHS England, is running at five hospital trusts in Oxford, Milton Keynes, Leicester, Liverpool and Wolverhampton.
A decision on its use within the NHS is expected within months.
Its developer, Oxford University spinout company Caristo Diagnostics, said it was already working to adapt the technology to prevent strokes and diabetes.
