An artificial intelligence (AI) model detects heart inflammation that conventional CT scans do not.
The pilot project, supported by the English National Health Service (NHS), is being carried out in five hospitals in the United Kingdom.
However, it is believed that the new technology will be rolled out across the country in the near future.
Caristo Diagnostics, a company founded at the University of Oxford, said it is already working to apply its technology to stroke and diabetes prevention.
“For the first time, we can identify biological processes invisible to the human eye that occur before the narrowing and occlusion of a blood vessel occurs,” said Professor Keith Channon of the University of Oxford, highlighting the advantages of the new technology.
In a pilot project, the artificial intelligence platform CaRi-Heart AI performs imaging analysis on patients with chest pain who would be scheduled for a CT scan according to the conventional algorithm.
The algorithm, which detects inflammation and plaque in the coronary arteries, is then evaluated by trained professionals to verify its accuracy.
The study found that increased inflammation is associated with a higher risk of cardiovascular disease and fatal heart attacks.
According to the British heart fund (BHF), about 7.6 million people in the United Kingdom (UK) suffer from heart disease. people and annual NHS spending of £7.4bn. pounds sterling (more than 8.6 billion euros).
About 350,000 cardiac CT scans are performed annually in the country. patients, says the BHF.
In a study published in the journal Lancet, which was attended by 40 thousand patients, it was found that 80 percent people were referred back to primary care professionals after the study without any prevention or treatment plan.
Researchers who looked at these patients found that if they had inflammation in their coronary arteries, they were 20 to 30 times more likely to die from a heart attack over the next 10 years.
During a study funded by the BHF, it was found that using artificial intelligence technology, 45 percent these patients were given medication or encouraged to make lifestyle changes to prevent them from having a heart attack.
Concerned about health
58-year-old British Ian Pickford in 2023. In November, he was sent for a CT scan because of constant pain in his chest.
The man has now been put on statin treatment, told to quit smoking and advised to increase exercise after an AI analysis showed he was at risk of a heart attack.
The results of the study led I. Pickford to worry about his health.
“When you see the results on paper, you understand how serious it is. “I have to change something,” I remind myself every day, I. Pickford said.
Research leader prof. Charalambos Antoniades said the tools available so far were primitive because the calculators could only assess general risk factors, such as whether a patient had diabetes, smoked or was obese.
“Now, using artificial intelligence technology, we know exactly which patient’s arteries are damaged before the disease has developed.
This means that we can take early action and stop the disease process and treat the patient so that the disease does not develop and then prevent a heart attack,” said Mr. Antoniades.
The technology is currently being assessed by the National Institute for Health and Care Excellence to determine whether it should be rolled out across the NHS. The decision is still to be made in the US, and the technology is already approved for use in the European Union and Australia.
