Atherosclerosis is difficult to return to full normalcy, but its progression can be slowed by a healthy lifestyle and the use of medications such as aspirin. The cause of atherosclerosis is not yet completely clear, but it is associated with risk factors such as aging, dyslipidemia, hypertension, smoking, diabetes and abnormal glucose tolerance, and obesity. In order to slow down the process of atherosclerosis, attention should be paid to improve lifestyle: control risk factors such as high blood pressure, diabetes, quit smoking, limit alcohol; reasonable diet, reduce cholesterol, carbohydrate intake, eat more fresh vegetables and fruits; maintain appropriate physical activity; regular work and rest, maintain optimism, happy mood. Improvement of atherosclerosis can also be under the guidance of the doctor to use drugs, such as anti-platelet aggregation drugs aspirin, clopidogrel, etc., regulating blood lipid drugs such as atorvastatin, probucol, ezetimibe, etc.. If atherosclerosis leads to severe narrowing or even occlusion of blood vessels, interventional procedures such as stenting and balloon dilatation may be needed to recanalize the blood vessels and restore the blood supply.
