    This is the best summary I could come up with:

    The study, funded by the British Heart Foundation (BHF), looked at how AI might improve the accuracy of cardiac CT scans, which are used to detect blockages or narrowing in the arteries.

    Prof Charalambos Antoniades, chair of cardiovascular medicine at the BHF and director of the acute multidisciplinary imaging and interventional centre at Oxford, said: “Our study found that some patients presenting in hospital with chest pain – who are often reassured and sent back home – are at high risk of having a heart attack in the next decade, even in the absence of any sign of disease in their heart arteries.

    About 350,000 people in the UK have a CT scan each year but, according to the BHF, many patients later die of heart attacks due to their failure in picking up small, undetectable narrowings.

    Researchers analysed the data of more than 40,000 patients undergoing routine cardiac CT scans at eight UK hospitals, with a median follow-up time of 2.7 years.

    Antoniades added: “We hope that this AI tool will soon be implemented across the NHS, helping prevent thousands of avoidable deaths from heart attacks every year in the UK.”

    Prof Sir Nilesh Samani, medical director at the BHF, said the research “shows the valuable role AI-based technology can play” in identifying those most at risk of future heart attacks.
