Artificial intelligence system can diagnose heart disease

 

 

 

 

 

British scientists have developed a new artificial intelligence system that can diagnose heart disease in a timely manner, better than doctors. A second system does something similar to lung cancer. The first system, which was developed at Oxford’s John Radcliffe Hospital and can “see” the critical examinations out of the doctor’s eye, is expected to be used free of charge in the National Health System (NSI) hospitals in Britain by this summer.

The system is thought to be able to save several billion pounds, thanks to the early diagnosis of illnesses and hence their more effective treatment. Oxford University Professor of Medicine Sir John Belle told the BBC that artificial intelligence “can save the NHS”, which is facing ever greater costs.

Artificial Intelligence is estimated to significantly reduce the costs of the British NHS (at least 300 million pounds per year) as, amongst other things, many patient interventions could be avoided thanks to the most timely and accurate diagnoses. According to British estimates, about one in five cardiac examinations is not diagnosed correctly today.

So far, the Ultromics system, developed by a team of researchers under Cardiac Professor Paul Lizon, has been tested in six cardiac clinics, and the official results of clinical trials are expected to be published this year. According to the researchers, efficacy seems to go beyond that of doctors in diagnosis and in assessing the likelihood of each patient becoming infected in the future.

Ultromics was initially trained to study the examinations of 1,000 patients who had been hospitalized over the past seven years, along with the analysis of additional information as to whether each patient eventually developed heart disease. Along the way, the system learned to diagnose itself.

“As cardiologists we have to admit at present that we are not always doing the right diagnosis. But with the new system, there is a chance that we will do better now. If this is confirmed, the new system will become available free of charge to all NHS hospitals in the country, “said Dr. Lizon.

A similar artificial intelligence system has been developed for the early diagnosis of lung cancer. The system detects the pulmonary nodes and distinguishes them harmless from the dangerous ones. Today doctors can not be certain whether some nodules will develop into cancerous patients, so patients need to perform periodic imaging tests to determine the progression of the nodules.

The new “smart” system, as shown by its clinical trials so far, can save patients suffering from cancer from stress for many months, as well as being able to diagnose cancer cases earlier than doctors.

The commercial exploitation of the system is being undertaken by the newly established Optellium, whose scientist Dr. Timor Kadir estimated that, if the system was widely used by British and European hospitals, it could achieve savings of 10 billion euros in medical expenses.
