Artificial intelligence-based method predicts | EurêkAlert!


BOSTON – Atrial fibrillation, an irregular and often rapid heart rate, is a common condition that often leads to clots in the heart that can travel to the brain to cause a stroke. As described in a study Posted in Circulation, a team led by researchers at Massachusetts General Hospital (MGH) and the Broad Institute at MIT and Harvard developed an artificial intelligence-based method to identify patients at risk of developing atrial fibrillation and who might therefore benefit from preventive measures.

Researchers developed the artificial intelligence-based method to predict the risk of atrial fibrillation over the next five years based on EKG results (non-invasive tests that record electrical signals from the heart) in 45,770 patients receiving primary care at the MGH.

Next, the scientists applied their method to three large datasets from studies comprising a total of 83,162 individuals. The AI-based method predicted the risk of atrial fibrillation on its own and was synergistic when combined with clinical risk factors known to predict atrial fibrillation. The method was also highly predictive in subsets of individuals such as those with previous heart failure or stroke.

“We see a role for EKG-based artificial intelligence algorithms to help identify those most at risk for atrial fibrillation,” says lead author Steven A. Lubitz, MD, MPH, cardiac electrophysiologist at MGH and associate member at the Broad Institut. Co-lead author Shaan Khurshid, MD, MPH, researcher in electrophysiology and researcher at MGH, adds co-lead author: “The application of such algorithms could prompt clinicians to modify important risk factors for fibrillation. little finger, which could completely reduce the risk of developing the disease.

Lubitz adds that the algorithm could serve as a pre-screening tool for patients who may currently have undetected atrial fibrillation, prompting clinicians to look for atrial fibrillation using longer-term heart rate monitors, which in turn could lead to stroke prevention measures. .

The study results also demonstrate the potential power of AI, which in this case involves a specific type called machine learning, to advance medicine. “With the explosion of data science technologies and the vast amounts of clinical data now available, machine learning is poised to help clinicians and researchers make great strides in improving patient care. cardiology, ”said co-author Anthony Philippakis, MD, PhD, chief data officer. at Broad and co-director of the institute’s Eric and Wendy Schmidt Center. “As a data scientist and former cardiologist, I am excited to see how machine learning-based methods can work with the tests and clinical approaches we use daily to help us improve risk prediction and take into account supports patients with atrial fibrillation. “
