New Technology Predicts the Risk of Irregular Heartbeat

An artificial intelligence-based method for identifying patients who are at risk for developing atrial fibrillation was developed by a team of researchers at Massachusetts General Hospital (MGH) and the Broad Institute of MIT and Harvard.

Atrial fibrillation is an irregular and often rapid heart rate condition that often leads to the formation of clots in the heart that can travel to the brain to cause a stroke.

‘The artificial intelligence-based method can prompt clinicians to modify important risk factors for atrial fibrillation that may reduce the risk of developing the disease altogether.’

Therefore, people who are identified with risk for developing atrial fibrillation could benefit from preventative measures. The research findings are published in the journal, Circulation.

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

Next, they applied their method to three large data sets from studies including a total of 83,162 individuals.

The AI-based method predicted atrial fibrillation risk on its own and was synergistic when combined with known clinical risk factors for predicting atrial fibrillation. The method was also highly predictive in subsets of individuals such as those with prior heart failure or stroke.

"We see a role for electrocardiogram-based artificial intelligence algorithms to assist with the identification of individuals at greatest risk for atrial fibrillation," says senior author Steven A. Lubitz, MD, MPH, a cardiac electrophysiologist at MGH and associate member at the Broad Institute.

This method could serve as a form of pre-screening tool for patients who are currently experiencing undetected atrial fibrillation, prompting clinicians to search for atrial fibrillation using longer-term cardiac rhythm monitors, which could lead to stroke prevention measures.

These findings also demonstrate the potential power of AI, which involves a specific type called machine learning to advance medicine. Machine learning is also poised to help clinicians and researchers make great strides in enhancing cardiology care.
