PHILADELPHIA – An artificial intelligence platform that sends alerts based on electrocardiography results enabled cardiologists and emergency department physicians at a major hospital in Taiwan to move patients with ST-elevation myocardial infarction (STEMI) into the catheterization laboratory 9 minutes sooner than the conventional protocol that did not use AI.
"This is the first randomized clinical trial to demonstrate the reduction of electrocardiography to coronary cath lab activation time," from 52.3 to 43.3 minutes (P = .003), Chin Sheng Lin, MD, PhD, director of cardiology at the National Defense Medical Center Tri-Service General Hospital in Taipei City, said in presenting the results at the American Heart Association scientific sessions.
Dr. Lin reported results from the Artificial Intelligence Enabled Rapid Identify of ST-Elevation Myocardial Infarction Using Electrocardiogram (ARISE) trial. The trial included 43,994 patients who came to the hospital's emergency and inpatient departments with at least one ECG but no history of coronary angiography (CAG) in the previous 3 days between May 2022 and April 2023.
They were randomly assigned by date to either AI-ECG for rapid identification and triage of STEMI or standard care. Overall, 145 patients were finally diagnosed with STEMI based on CAG, 77 in the intervention group and 68 in the control group.
