Cardiovascular health is one of the leading causes of deaths all over the world. The Centers of Disease Control and Prevention states that every 34 seconds a person dies from cardiovascular disease (CVDs). Statistics show 919,032 deaths due to CVDs in the US in 2023. Globally the number is even bigger, hence why people are advised to take better care of their health, whether it is in terms of food, exercise or mental health. A big reason why we have been able to proactively avoid heart issues is because of the advancement in medicine through tests and research. These findings have helped us stay healthy and avoid issues in the future. Another such aid has been made through a recent study, which could predict heart events years before it even happens. A recent study done by the British Heart Foundation, suggest that a quick eye test, taking less than a minute, might be able to predict your risk of having a heart attack or stroke in the next ten years. Scientists have developed an advanced computer system that analyzes digital pictures of the back of your eye. This technology can quickly provide a personalized assessment of your risk. The hope is that this simple and easy test could become a regular part of health check-ups, just like measuring blood pressure or cholesterol, helping doctors spot potential problems as early as possible. Peering into the Eye's Blood Vessels This new technology uses the idea that the tiny blood vessels in your eyes can give important clues about the health of blood vessels throughout your entire body. This includes the ones that supply your heart and brain. It might seem surprising, but specialists say that your eyes are like a "window to your heart." If there's any damage or narrowing in the blood vessels at the back of your eye, it's likely that similar issues are happening in the blood vessels deeper inside your body, which could eventually lead to a heart attack or stroke. Learning from Diabetic Eye Scans Researchers taught this advanced computer system using eye scans from people who have type 2 diabetes. These individuals regularly have their eyes checked for a condition called diabetic retinopathy, where high blood sugar can harm the blood vessels in the retina. The system was first taught to recognize potential warning signs in these images, such as narrowed or blocked blood vessels. Then, it was allowed to examine every tiny detail within the pictures, including the size or shape of blood vessels, and was trained using a large collection of over 4,000 images. Accurately Predicting Cardiovascular Events The AI technology was quite successful in predicting which individuals would experience serious heart problems, like heart attacks or strokes, within a decade. It was accurate about 70% of the time. Experts point out that this is a single, quick scan that is already done routinely and takes less than a minute. They believe it could become a very important part of overall health checks, alongside blood pressure and cholesterol tests, to help identify people who could benefit from medications or changes to their lifestyle. Game-Changer for Heart Health Leaders in the field emphasize that the more precisely we can figure out someone's risk of a heart attack or stroke, the better we can prevent these events from happening. They see innovative advancements like using eye scans alongside other health checks as a key way to improve how we predict risk. This is very important if we want to reach the goal of preventing a significant number of heart attacks and strokes in the future. Experts also suggest that such advances could make it much easier for people at risk of stroke to take the necessary steps to prevent it. While there are still many practical questions about how and when this AI could be used in regular medical care, there's hope that future health plans will consider these technological advancements to save more lives.
