Hyperlipidemia is defined as fasting plasma concentrations of total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), or triglycerides (TG) that are above the upper limit of normal. Since lipid concentrations are influenced by many factors, such as diet, heavy alcohol consumption, emotional stress, nervousness, pregnancy, etc., the diagnosis is established only if fasting lipids are consistently above normal. After more than 100 years of exploration, human beings have fully recognized that dyslipidemia has a very close relationship with the occurrence and development of atherosclerosis. After a large number of epidemiological, basic and clinical studies, it is now clear that elevated plasma cholesterol, especially LDL-cholesterol levels, is a pathogenic risk factor for coronary heart disease, and that active lipid-regulating therapy can significantly reduce the disability and mortality rates of coronary heart disease. At present, the strongest drugs for lowering cholesterol and LDL-cholesterol are “statins”, and the more clinically used ones are simvastatin, atorvastatin, fluvastatin, reserpinevastatin, pravastatin, etc. This kind of drugs is the only lipid-regulating drugs that can be proved to reduce the total mortality rate of patients with coronary heart disease. Therefore, statins have now become the basic therapeutic drugs for coronary heart disease. Therefore, in order to effectively prevent and treat coronary heart disease, all patients with coronary heart disease as well as patients with risk factors for coronary heart disease (high blood lipids, high blood pressure, diabetes mellitus, advanced age, etc.) need to adequately apply statins. And adhere to a healthy lifestyle. In life, it is still required to “keep your mouth shut and your legs open”. Dietary control, meals to “not hungry” as the standard, what can eat what to eat less, to maintain the ideal weight and waist circumference. Exercise 6,000-10,000 steps a day, depending on your physical condition. Stop smoking and drinking.
