CHICAGO — A patient’s risk of a heart attack or stroke in the next 10 years can be predicted from just one chest X-ray by a new computer system.
Researchers with the Radiological Society of North America say it combines AI (artificial intelligence) with a standard X-ray to find patterns associated with hardening of the arteries. The technique offers hope that doctors will be able to prescribe vulnerable individuals cholesterol-reducing drugs before it’s too late.
“Our deep learning model offers a potential solution for population-based opportunistic screening of cardiovascular disease risk using existing chest X-ray images,” says study lead author Jakob Weiss, M.D., a radiologist affiliated with the Cardiovascular Imaging Research Center at Massachusetts General Hospital and the AI in Medicine program at the Brigham and Women’s Hospital in Boston, in a media release.
“This type of screening could be used to identify individuals who would benefit from statin medication but are currently untreated.”
Eating plenty of fish, fruit and vegetables, and going for brisk walks or bike rides are also protective habits that can lower heart disease risk.
Deep learning is a complex series of algorithms that enable machines to make forecasts based on patterns in data. The method, presented at the annual meeting of the RSNA in Chicago, could revolutionize heart therapy.
Current guidelines recommend estimating a patient’s 10-year risk to establish who should take statins for primary prevention. This is based on the ASCVD (atherosclerotic cardiovascular disease) risk score which takes into account a host of factors. They include age, sex, race, high blood pressure, smoking history, Type 2 diabetes, and blood tests. Those scoring 7.5 percent or more should receive statins.
“The variables necessary to calculate ASCVD risk are often not available, which makes approaches for population-based screening desirable,” Dr. Weiss says. “As chest X-rays are commonly available, our approach may help identify individuals at high risk.”
The U.S. team trained the model, known as CXR-CVD risk, to predict death from cardiovascular disease using 147,497 chest X-rays from 40,643 participants in a cancer screening trial.
“We’ve long recognized that X-rays capture information beyond traditional diagnostic findings, but we haven’t used this data because we haven’t had robust, reliable methods,” Dr. Weiss continues. “Advances in AI are making it possible now.”
In tests, the system accurately predicted heart attacks and strokes in a group who had routine chest X-rays at Mass General Brigham. About 10 percent of the 11,430 outpatients suffered a major cardiac event over the average follow-up of just over a decade. The system also identified those who were eligible for potentially life-saving statin therapy.
“The beauty of this approach is you only need an X-ray, which is acquired millions of times a day across the world,” the study author explains. “Based on a single existing chest X-ray image, our deep learning model predicts future major adverse cardiovascular events with similar performance and incremental value to the established clinical standard.”
If a controlled, randomized trial validates the results it could support doctors in making the right decisions for treatment.
“What we’ve shown is a chest X-ray is more than a chest X-ray,” Dr. Weiss concludes. “With an approach like this, we get a quantitative measure, which allows us to provide both diagnostic and prognostic information that helps the clinician and the patient.”
Cardiovascular disease is the world’s number one killer – claiming almost 18 million lives a year.

So what metrics in the x-rays are the AI analyzing. And what is it’s technique? And where is the source code for this? I’ve read so many articles about AI being able to do so much, yet rarely does it deliver.
And it’s not like they can’t patent or copyright source code. If you make claims about something you better be able to prove them. Source code or this isn’t true.
I read that statins for over 75 age did more harm then good?
f my cholesterol is 250 doc said well we can test it again in 6 mos. No statins for now.
so do i need statins? who is to say. Im confused. both parents died of heart diease, h blood p
h cholesterol etc. Am I doomed?
Study was based on chest x-rays from a cancer screening program, presumably smokers, so any conclusion about results is limited to that group. Similar findings might also exist in non-smokers, but this would require a separate study.
AI once predicted that I was going to die someday. Genius!
Jab takers have a huge risk of a heart attack or stroke in the next 10 years.
Your proof?cite your source. Fool
Exercise and good food are important, but a healthy spirit is most important. Not holding grudges and being kind will add years to one’s health.
I wish that was true. My brother in law, one of the most zen and kind persons I have ever known, had a catastrophic cardiac arrest two weeks ago and is about to be removed from life support. He’d had some cardiac symptoms he ignored for months, thinking oh, it’s nothing. I truly wish his healthy spirit had been able to overcome this fatal cardiac event, but what the family has taken from this tragedy is that one must not ignore heart symptoms.
Welcome to the new world of medicine made possible by Artificial Intelligence:
“A patient’s risk of a heart attack or stroke in the next 10 years can be predicted from just one chest X-ray.”
And we ain’t seen nothing yet. Hold on to your hats.
They say this stuff, but they never prove it with the source code. I can tell you that I made a computer program that will accurately predict when the sky will fall. You can say anything if you’re not being called on to prove your claims.
Most of this article’s attention was dedicated to statin use as a primary way to prevent MI and CVA. Thankfully, you did include, “Eating plenty of fish, fruit and vegetables, and going for brisk walks or bike rides are also protective habits that can lower heart disease risk.” As a therapist on a stroke unit, I would argue that dietary changes, exercise regiments, blood sugar regulation, smoking cessation, and learning ways to manage stress would go a long way toward preventing the need for statins in the first place. As exciting as AI is with its ability to predict illness, let’s not forget about the “low hanging fruit” of lifestyle changes. As an added benefit, diet and exercise don’t come with side-effects.
But is it low hanging fruit? We have know for decades what lifestyle changes to make to reduce CVD and have made little progress or have slipped further.
That is a good point. Exercise simply isn’t an option for people who weren’t born into wealth. Neither is a healthy diet. Knowing the scientifically-proven best approach doesn’t mean you can afford it.
