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 aspirin can be taken orally. Vitamin E has a softening effect on blood vessels, and statins 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 a blood vessel somewhere with blood circulation and cause an embolism. Embolism in the leg blood vessel will appear leg pain, embolism in the heart blood vessel will appear myocardial infarction, etc. Once the neck plaque appears, it should be treated in time.
