LEEDS, United Kingdom (StudyFinds.org) — An artificial intelligence system is capable of spotting whether someone will have a heart attack within the next year — through a routine eye scan.
A team from the University of Leeds believes this AI tool opens the door to a cheap and simple screening program for the world’s number one killer. Their tests find the computer can predict patients at risk of a heart attack in the next 12 months with up to 80% accuracy. The breakthrough adds to evidence that our eyes are not just “windows to the soul,” but windows to overall health as well.
“Cardiovascular diseases, including heart attacks, are the leading cause of early death worldwide and the second-largest killer in the UK. This causes chronic ill-health and misery worldwide,” project supervisor Professor Alex Frangi says in a university release.
“This technique opens-up the possibility of revolutionizing the screening of cardiac disease. Retinal scans are comparatively cheap and routinely used in many optician practices. As a result of automated screening, patients who are at high risk of becoming ill could be referred for specialist cardiac services,” Frangi adds.
“The system could also be used to track early signs of heart disease.”
The retina is a small membrane at the back of the eye containing light sensitive cells. Doctors have found that changes to the tiny blood vessels can hint at vascular disease, including heart problems.
Study authors used an advanced type of AI, known as deep learning, to teach the machine to automatically read more than 5,000 eye scans. The scans come from routine eye tests during visits to opticians or eye clinics. All of the participants are part of the UK Biobank, which tracks the health of half a million adults.
Deep learning is a complex series of algorithms that enable machines to make forecasts based on patterns in data. The technique, described in the journal Nature Machine Intelligence, could revolutionize heart therapy, according to the researchers.
“The AI system has the potential to identify individuals attending routine eye screening who are at higher future risk of cardiovascular disease, whereby preventative treatments could be started earlier to prevent premature cardiovascular disease,” says co-author Professor Chris Gale, a consultant cardiologist at Leeds Teaching Hospitals NHS Trust.
The study identified associations between pathology in the retina and changes in the patient’s heart. Once the system learned each image pattern, the AI could estimate the size and pumping efficiency of the left ventricle from retinal scans alone.
This is one of the heart’s four chambers. An enlarged ventricle can increase the risk of heart disease. The computer combined the estimated size of the left ventricle and its pumping efficiency with data like age and sex.
Currently, doctors determine this information using an MRI (magnetic resonance imaging) or echocardiography scans of the heart. The diagnostic tests are expensive and are often only available in a hospital. The tests can be inaccessible for many people in countries with lesser health care systems. They also increase health care costs and waiting times in wealthy nations.
“The AI system is an excellent tool for unravelling the complex patterns that exist in nature, and that is what we have found – the intricate pattern of changes in the retina linked to changes in the heart,” adds co-author Sven Plein of the British Heart Foundation.
A recent study discovered a similar link between biological aging of the retina and mortality. Those with a retina “older” than their actual age were up to 67% more likely to die over the next decade.

SAVANNAH, Ga. (WSAV) – Second Harvest of the Coastal Empire that started in 1981 has come a long way from serving food out the back of a pickup truck to distributing over 28 million pounds of food in 2021.
“We serve around 147,000 people each year through coastal Georgia,” says executive director Mary Jane Crouch. “We actually serve 21 counties in coastal Georgia.”
BRUNSWICK, Ga. (WSAV) – Defense attorneys for two of the men convicted in Ahmaud Arbery’s murder are deliberating if they’ll withdraw guilty pleas after a federal judge rejected a plea deal on Monday.
Under the deal, Travis McMichael would have pleaded guilty, admitting he targeted Arbery based on his race. After the judge rejected Travis’ plea deal, the hearing for his father, Greg, was canceled.
POOLER, Ga. (WSAV) – The Children’s Museum of Pooler is continuing its monthly sensory-friendly mornings this month.
The events aim to create a space for children with developmental disabilities to explore without becoming overstimulated. They have been going on since the start of the museum almost two years ago and occur every second Wednesday of the month.
