Scientists have developed an artificial intelligence (AI) system that can better predict the risk of death in patients with heart disease than human experts. In a study published in the journal PLOS One, researchers showed how the AI could revolutionise health care.<br />” <br />”The model was designed using the electronic health data of over 80,000 patients, collected as part of routine care. Coronary artery disease develops when the major blood vessels that supply the heart with blood, oxygen and nutrients become damaged or narrowed by fatty deposits. Eventually, restricted blood flow to the heart can cause a heart attack.<br />” <br />”An expert-constructed prognostic model for coronary artery disease made predictions based on 27 variables chosen by medical experts, such as age, gender and chest pains.<br />”<br />”<span style="color: #222222;">By contrast, the AI algorithms to train themselves, search for patterns and make predictions based on a set of 600 variables.</span><br />
