Atherosclerosis cannot be cured, but its progression can be slowed by a healthy lifestyle, medication such as aspirin, and if necessary, interventional therapy. Atherosclerosis can involve multiple arteries throughout the body, such as the aorta, coronary arteries, cerebral arteries, limb arteries, etc. The cause is still unclear, and it is related to risk factors such as increasing age, dyslipidemia, hypertension, smoking and diabetes. To improve atherosclerosis, lifestyle should pay attention to: quit smoking, limit alcohol, actively control related underlying diseases such as hypertension, diabetes mellitus, etc.; adjust the dietary structure, control the total calorie, reduce the intake of fats, oils and cholesterol; daily moderate physical exercise, maintain a positive and optimistic mood. On the basis of lifestyle adjustment, anti-platelet drugs such as aspirin, clopidogrel, etc. and lipid regulating drugs such as atorvastatin, ezetimibe, etc. can also be used under the guidance of the doctor to slow down the progress of atherosclerosis. If atherosclerotic vessels are severely narrowed or occluded, resulting in localized blood flow obstruction, interventional surgery can be used to restore arterial patency as soon as possible to avoid further damage by means of stenting and balloon dilatation.
