When it comes to atherosclerosis, I believe we should not be unfamiliar with it. Atherosclerosis is the main cause of coronary heart disease, cerebral infarction, and peripheral vascular disease. Especially for middle-aged and elderly people, it is important to pay special attention. So how should atherosclerosis be prevented in life? I. What is atherosclerosis? Atherosclerosis occurs when lipids in the blood are deposited in the inner wall of blood vessels, and calcium salts are also deposited here, and the long-term accumulation causes changes in the structure of blood vessels and the proliferation of connective tissue, resulting in the thickening of the local intima of blood vessels and the formation of plaques in blood vessels, and over time, there are atheromatous materials softening in the deep part of the plaques, which is atherosclerosis. Second, the harm of atherosclerosis 1, coronary artery atherosclerosis: if the diameter of the narrowing of more than 75%, angina pectoris, myocardial infarction, arrhythmia, and even sudden death; 2, cerebral artery atherosclerosis can cause cerebral ischemia, cerebral atrophy, or cerebral vascular rupture bleeding; 3, renal artery atherosclerosis often causes nocturia, intractable hypertension, serious cases may have renal insufficiency; 4, mesenteric artery atherosclerosis Sclerosis can be manifested as abdominal pain after a full meal, indigestion, constipation, etc. In severe cases, necrosis of the intestinal wall can cause blood in the stool, paralytic intestinal obstruction and other symptoms; 5, atherosclerosis of the lower limbs can cause severe narrowing of the lumen of the blood vessels, intermittent claudication, dorsal foot artery pulsation disappearance, and in severe cases, gangrene can even occur. Third, atherosclerosis risk factors Atherosclerosis is caused by the joint action of multiple factors, and its pathogenesis is complex and not yet fully understood. However, the main risk factors are obesity, heavy smoking, hypertension, hyperlipidemia, diabetes and genetic factors. Fourth, life should be how to prevent atherosclerosis 1, scientific and healthy diet: prevention of the disease, first of all, we must rationalize the diet, advocate a light diet, eat low sugar, low salt, low cholesterol, low fat food, vegetable oil, coarse and fine weeds with, eat more low-sugar fruits and fiber-rich food; eat vegetables often, avoid overeating; 2, followed by avoiding alcohol and tobacco; 3, control the weight gain: Generally to body mass index (BMI) 20 ~ 24 for normal weight. Or waist circumference as a standard residence, generally to women ≥ 80cm, men ≥ 85cm for overweight; 4, appropriate exercise: physical activity should be gradual, should not be forced to do strenuous activities, can participate in the usual walking, taijiquan and other physical activities, it is recommended that at least 30 minutes of moderate intensity exercise every day, in order to feel less strenuous; 5, regular life: reasonable arrangements for work and life, combined with work and rest, sleep enough 6, but also to maintain mental optimism, maintain an optimistic and happy mood; 7, active treatment of diseases related to the disease, such as hypertension, obesity, hyperlipidemia, gout, diabetes, liver disease, nephrotic syndrome and related endocrinopathies; 8, lifelong use of aspirin antithrombotic, long-term or lifelong use of statin lipid-regulating drugs; 9, regular review of lipids and arterial ultrasound (carotid artery, subclavian artery, upper limb artery, lower limb artery), coronary CTA, cranial artery CTA, and angiography.
