Arteriosclerosis is a non-inflammatory, degenerative and proliferative lesion of the artery, which can cause thickening, hardening, loss of elasticity of the artery, and can lead to lumen narrowing. Because the lipids that accumulate in the lining of the arteries have a yellow atherotic appearance, they are called atherosclerosis.
Lipid metabolism disorders are the basis of atherosclerosis, which is characterized by the involvement of arterial lesions starting from the intima and generally having lipid and complex carbohydrate accumulation, hemorrhage and thrombosis, followed by fibrous tissue proliferation and calcinosis, and gradual metamorphosis and calcification of the middle layer of the artery, resulting in thickening and hardening of the arterial wall and narrowing of the vascular lumen.
None of them. 
As we age, the study of arterial elasticity gradually declines significantly, and to some extent severe atherosclerosis develops. It can be divided into atherosclerosis, medial arteriosclerosis and arteriolar sclerosis.
Atherosclerosis is the basic disease of aging, because we have a very important impact on the blood management circulation of the organs that affect atherosclerosis, which will undoubtedly affect the immune capacity information system and accelerate the aging design teaching process. Atherosclerosis is the main cause of coronary heart disease, cerebral infarction, and peripheral vascular disease.
The main causes of atherosclerosis are high blood pressure, high blood lipids, and smoking, among others. The nicotine and carbon monoxide in cigarettes can damage the lining of the arteries, which can clog cholesterol, causing platelets to become fat plaques.
At the same time, smoking can also cause coronary artery constriction and spasm, reducing blood flow.
People who don't exercise are more likely to get atherosclerosis. People who are obese or overweight have a higher risk of heart disease and dyslipidemia. Stress increases the release of adrenaline, which can lead to increased blood pressure, a faster heartbeat, and damage to the arterial lining.
Genetic factors in some people's family history start with the early occurrence of traffic atherosclerosis in China, the cause is not clear, and some are severe hypercholesterolemia, which accumulate in our blood and promote the development of economic atherosclerosis. Some have early-onset hypertension or are prone to thrombosis.
There are many blood tests to check for atherosclerosis: blood cholesterol and triglycerides are often elevated, and HDL is low. X-ray: dilated and twisted aorta and sometimes calcinosis.
Fundus examination: arteriosclerosis may be seen.
Doppler ultrasound: Tests help determine blood flow in the carotid, extremity, and renal arteries.
Arteriography: may show the narrowing, location, and extent of the lumen of the limb arteries, renal arteries, and coronary arteries caused by atherosclerosis.
