Study Highlights the Limits of AI in Heart Care
There are limits in applying AI to images of the heart, a new study from the Smidt Heart Institute at Cedars-Sinai reveals. The findings were published in the Journal of the American Society of Echocardiography.
Investigators trained multiple artificial intelligence models to read images from echocardiograms, a type of ultrasound test that evaluates the structure and function of the heart. Their goal was to determine whether AI could use these images to calculate measurements like inflammation and scarring that are normally obtained through another, more costly test called cardiac magnetic resonance imaging (CMRI). By examining findings from 1453 patients who had undergone both tests, they found the AI models could not accomplish this task.
“As compared to echocardiograms, cardiac MRI machines are expensive and not available for many patients, especially those in rural areas, so we had hoped that AI could reduce the need for it,” said Alan Kwan, MD, assistant professor in the Department of Cardiology in the Smidt Heart Institute at Cedars-Sinai and co-senior author of the study. “Our results showed the limited powers of AI in this area.”
