An AI trained on the heart's electrical activity alerted physicians about patients at high risk of dying, significantly reducing deaths in a clinical trial with almost 16,000 patients at two hospitals

An artificial intelligence system has proven it can save lives by warning physicians to check on patients whose heart test results indicate a high risk of dying. In a randomised clinical trial with almost 16,000 patients at two hospitals, the AI reduced overall deaths among high-risk patients by 31 per cent.at the Scripps Research Translational Institute in California, who was not involved in the research.

The researchers then tested the AI alert system with 39 physicians at two different hospitals. As nurses uploaded each new patient’s ECG tests to a computer server, the AI system would analyse the results and quickly alert physicians if it identified the patient as being high risk. In addition to reducing the risk of death from all causes, the AI system reduced high-risk patients’ deaths from heart issues by more than 90 per cent.may help focus attention on the highest risk group – physicians usually followed up on alerts with more diagnostic tests and additional treatment.“This can be implemented in every hospital around the world – it shouldn’t be expensive,” says Topol. “It should be the standard of care when you see this extent of magnitude of benefit.
