If atherosclerotic plaques exist in the blood vessels, there exists a certain possibility that the plaques will disappear if the plaques are stabilized by long-term administration of antiplatelet, lipid-lowering and anti-inflammatory drugs that improve the endothelial function of the blood vessels. Clinically commonly used drugs include bye aspirin and statins, but they must be taken for a long time to be expected to have such effect. Along with the application of drugs, it is also important to pay attention to proper exercise for weight loss, low salt and low fat diet, and eat more fresh fruits and vegetables during the weekdays. Control blood pressure and blood sugar well, because diabetes as well as hypertension can accelerate the progress of atherosclerosis. In clinical practice, a more common method to check the severity of atherosclerosis is to perform ultrasound examination of the neck vessels. Many patients may take lipid-lowering and anti-atherosclerosis drugs, but the plaque does not disappear, but if they can take long-term lipid-lowering and plaque-stabilizing drugs, they can also help prevent the progression of the disease and play the role of secondary prevention.
