Heart attack signs? The ophthalmologist has something to say

Editor's Note Heart disease is the leading cause of death worldwide, and early diagnosis and treatment can help prevent heart attacks and strokes. So how can we detect the signs of heart attack early? Ophthalmologists may be able to spot signs of heart disease during a comprehensive eye exam, as "eye strokes" are often seen in the retina of heart patients, a new study suggests. What is "eye stroke"? "Ocular stroke" mainly refers to sudden vision loss or loss caused by central retinal artery occlusion (CRAO), mainly caused by embolic embolism, atherosclerosis, endarteritis or arterial spasm, unless the occlusion is very brief, And remove the block in time, otherwise it will cause permanent visual damage. Because the central retinal artery is responsible for providing blood supply to the neural retina, its occlusion can lead to retinal infarction and edema. Therefore, optic disc edema and unclear boundary can be seen in the fundus of eye stroke patients, and retinal arterioles can be seen narrowed. Because of the blood supply from the choroid in the macular area, So it appears as a cherry red spot (pictured). Image via D D Varma's 2013 article in Eye How does an eye exam detect heart disease? The eye is the only living organ in the body where doctors can see blood vessels, nerves, and connecting tissue without relying on invasive surgery, which is why ophthalmologists often spot health problems such as high blood pressure, high cholesterol, and stroke first. Ocular strokes occur when the eye is ischemia and lack of oxygen, causing cells to die, creating traces that ophthalmologists can detect when they look closely at the retina using imaging tools such as optical coherence tomography (OCT). In fact, retinal OCT is an effective way to detect disease and dysfunction in various parts of the body, and eye scans can detect signs of Alzheimer's disease, Parkinson's disease, and other underlying health conditions. Healthy people had fewer stroke marks in the eyes, but people with heart disease had more stroke marks in the eyes. The researchers reviewed the medical records of 84 heart patients and 76 healthy people who underwent retinal OCT scans, and concluded that the retina of heart patients often showed signs of eye stroke. Early detection of heart disease can save lives Putting eye exams on your health checklist may help detect heart disease early, in the words of the researchers -- your eye doctor may see images of your fundus earlier than before , thereby helping you detect cardiovascular disease, which is undoubtedly good news for heart disease patients with a very high mortality rate. In the future, if an ophthalmologist detects signs of an eye stroke on an OCT scan, especially if the patient has not undergone a comprehensive health examination, or has a family history of heart disease, the ophthalmologist could refer the patient to a cardiologist, which is a life-saving behavior.
