Eye Scan Predicts Heart Attack & Stroke Risk
AI Detects Heart Attack and Stroke Risk from Eye Scans

An innovative artificial intelligence tool can predict the likelihood of a heart attack or stroke within a decade by analyzing scans of the back of the eye, a breakthrough that could revolutionize cardiovascular risk assessment.
A Window to the Heart
The AI technology, developed by researchers, examines the intricate network of blood vessels in the retina. “If there is damage or narrowing of the blood vessels at the back of the eye, there is a good chance that will also be seen in the blood vessels further inside the body, supplying the heart, which could lead to a heart attack or stroke,” explained Dr. Pearse Mordi,a lead researcher on the project.
The AI was initially trained to identify warning signs such as blood vessel narrowing or blockages. It was then allowed to analyze othre details like the size and arrangement of these vessels. After being trained on 4,200 images, the AI demonstrated a remarkable ability to predict major cardiovascular events, including heart attacks and strokes, within a ten-year timeframe wiht 70% accuracy.
A simple, Powerful Tool
dr. Mordi highlighted the practicality of this new approach. “This is a one-stop scan which is routinely performed and takes less than a minute,” he stated. “It could be an crucial part of the package, alongside blood pressure and cholesterol checks, in identifying people who could benefit from medication or lifestyle changes.”
This AI-driven analysis offers a non-invasive and efficient method for early detection, perhaps enabling timely interventions to prevent life-threatening events.
Expert Endorsements and future Outlook
Professor Bryan Williams, chief scientific and medical officer at the British Heart Foundation (BHF), acknowledged the potential of such cutting-edge innovations. “Cutting-edge innovations like the AI tool could play a role in improving risk prediction,” he commented. However, he also stressed the need for further research: “More research is needed to show this prediction accuracy is robust, and to determine the feasibility of incorporating retinal scans into clinical practice.”
Echoing this sentiment, Dr. Clare Jonas, research lead at the Stroke Association, expressed optimism about the role of AI in healthcare. “AI analyses of health data have exciting potential for better early detection,” she said. “advances like these could make it easier for people at risk of stroke to take the right steps to stop it from happening.”
Dr. Jonas added, “Whilst there are still many practical questions to answer about whether, when and how AI could be used in clinical practice, we hope the government’s 10 Year Health Plan will take such technological advances into account to stop more strokes from devastating people’s lives.”
The integration of AI into routine eye examinations could represent a critically important leap forward in proactive cardiovascular healthcare, offering a simple yet powerful method to identify individuals at high risk and empower them to take preventative action.
