Carotid plaque refers to the plaque in the inner wall of blood vessels that appears after carotid atherosclerosis, which is produced by the gradual stimulation of the inner wall of blood vessels by elevated blood lipids. The appearance of carotid plaque will lead to narrowing of blood vessel lumen, insufficient blood supply to the brain, and gradually produce symptoms such as dizziness and poor memory. If there are only mild dizziness symptoms, small doses of oral aspirin can be taken. Vitamin E has a softening effect on blood vessels, and simvastatin can lower blood lipids, and the combination of the two can improve the efficacy. As the plaque gradually increases, the dizziness will become more and more obvious, and there is a risk that the plaque will fall off, and the plaque will form a blood clot, which can block any part of the blood vessel with blood circulation. Blockage in the legs will lead to leg pain, blockage in the heart will lead to myocardial infarction, blockage in the kidney artery will lead to intractable hypertension, and once the plaque in the neck appears, it should be treated in time.
