A lot of people who have done carotid ultrasound, have had this experience: found that the blood vessel narrowing, plaque. Doctors will warn: be careful, it may develop into a cerebral infarction. Is plaque in the carotid artery a serious matter? Do you need to find plaque to sleep and eat? How does plaque form? The wall of the blood vessel is made up of three layers: the inner, middle, and outer molds, and the three layers are affixed together. In hypercholesterolemia, cholesterol in the blood will penetrate the inner membrane through a series of reactions and hide between the middle and inner membranes, gradually accumulating, thus causing the inner membrane to protrude and form a mass, which is what we call plaque. Cholesterol does not run under the endothelium by itself, it needs a transit process, and this medium, is LDL. Therefore, if the blood test found that the combined LDL cholesterol is elevated, we have to be vigilant. Do plaques always lead to cerebral infarction? This is a serious question. If it is detected early and the plaque is small, it will not block the blood vessel so easily. But what if you think it doesn’t matter and you can just ignore it? The consequences are terrible. Because once the plaque is not controlled, has been growing, the plaque is getting bigger and bigger, will naturally make the blood vessels become narrower, through the blood flow becomes less, and thus prone to blockage; In addition, due to the surface of the blood vessel wall produced plaque, not as smooth as before, this rough surface leads to the gathering of many other components of blood, such as red blood cells, white blood cells, platelets, fibrin, etc., so that the thrombus is easy to form, once Once dislodged, the embolus with the blood flow to the brain, cerebral infarction occurs. Therefore, carotid artery plaque, can not be ignored, of course, excessive tension is not necessary. With timely monitoring, proper diet and appropriate treatment, we can keep plaque under control and stay away from cerebral infarction.
