In the modern era, due to the busy routine, the number of heart patients is increasing continuously. In a recent research, scientists claim to have created an artificial intelligence-equipped device that can predict a person’s chances of having a heart attack. The findings of this study have been published in The Lancet Digital Health.
The device, created by investigators at Messiers-Sinai, accurately predicted which patients would have a heart attack over five years based on the amount and composition of plaque in the arteries that supply blood to the heart.
Study senior author Damini Day and her colleagues, director of the Quantitative Image Analysis Laboratory at the Biomedical Imaging Research Institute at Cedars-Sinai, and her colleagues collected CTAs from 1,196 people who underwent coronary CTA at 11 sites in Australia, Germany, Japan, Scotland and the United States. Images analyzed.
The investigators trained an AI algorithm to measure plaque by learning from coronary CTA images from 921 people, which had already been analyzed by trained doctors.
The algorithm works by first profiling coronary arteries in 3D images, then identifying blood and plaque deposits within the coronary arteries.
The investigators found that the instrument’s measurements were consistent with the plaque volume seen in coronary CTAs. They matched the results with images taken by intravascular ultrasound and catheter-based coronary angiography, two tests considered highly accurate in assessing coronary artery plaque and narrowing.
In the end, the investigators found that measurements made by an AI algorithm from CTA images accurately predicted heart attack risk within five years for 1,611 people who were part of a multicenter trial called the Scott-Hart trial.
More study is needed, Day said, but it is possible that we can predict whether a person is likely to have a heart attack based on the amount and composition of plaque painted with this standard test.
Day and his colleagues are continuously studying how well their AI algorithm determines the amount of plaque deposits in patients undergoing coronary CTA.
Let’s guess like this-
The accumulation of plaque can narrow the arteries, making it difficult for blood to reach the heart, which increases the chances of a heart attack.
A medical test called coronary computed tomography angiography (CTA) takes 3D images of the heart and arteries and can give doctors an idea of how narrowed a patient’s arteries have become. Until now, however, there has not been a simple, automatic and rapid way to measure the plaque visible in CTA images.
test in six seconds
Coronary plaque isn’t often measured, Day said, because there isn’t a fully automated way to do it. When it is measured, it takes at least 25 to 30 minutes, but now we can use it to measure plaque in CTA images in just five to six seconds.
