At present, cardiovascular and cerebrovascular diseases have become the first cause of death in China’s urban and rural populations, accounting for nearly 40% of the causes of death of China’s residents. 2005 information released by the Ministry of Health shows that: China has about 3 million people die of cardiovascular diseases every year, about 8,000 people every day, and 500,000 and 2 million people suffer from myocardial infarction and hemiplegia every year, respectively. And with the change of people’s lifestyles, this proportion is still expanding year by year. The most common cardiovascular and cerebrovascular diseases in China are coronary heart disease and cerebral thrombosis, whose pathological basis is atherosclerosis, and dyslipidemia is one of the main risk factors causing atherosclerosis. Lipid is a general term for lipids in plasma, including cholesterol, triglycerides, lipids and phospholipids, etc. Cholesterol includes LDL cholesterol (commonly known as “bad” cholesterol) and HDL cholesterol (commonly known as “good” cholesterol). Total cholesterol, triglycerides, LDL and HDL are the most commonly measured lipids. Elevated levels of the first three indicators can lead to dyslipidemia, with LDL being the most harmful. Harmful lipids can be deposited on the blood vessel wall to form atherosclerotic plaques, as the plaque continues to grow, the degree of arterial stenosis gradually increased, and even blockage, thus causing angina pectoris, myocardial ischemia, cerebral infarction, cerebral softening. What is even more terrible is that these plaques are like dumplings with thin skin and much oil, which will rupture without any warning and quickly block the blood vessels, triggering acute myocardial infarction or even sudden death. Despite the seriousness of the danger of dyslipidemia, dyslipidemia may be asymptomatic for quite a long time, and it is easy to be ignored. According to statistics, the number of dyslipidemia people over 18 years old in China has reached 160 million. Dyslipidemia is mainly caused by poor lifestyle, including excessive intake of high cholesterol food, reduced exercise. Dyslipidemia seriously jeopardizes life and health, and a large number of studies have confirmed that a 1% reduction in total cholesterol can reduce the risk of coronary heart disease by 2%. In general, the more risk factors for cardiovascular disease, the greater the risk of ischemic cardiovascular events, the stricter the lipid control should be. Lipid-lowering goals are different for different people. It is recommended that adults over 20 years of age should have their fasting lipids measured at least once every 5 years; people with coronary heart disease, hypertension, diabetes, and obesity should have their lipids measured once every 3 months to 6 months. Control of dyslipidemia mainly includes therapeutic lifestyle changes and drug therapy. Therapeutic lifestyle changes are regarded as the most cost-effective way to lower LDL, including: (1) reducing the intake of saturated fat and cholesterol; (2) increasing the intake of plant sterols and soluble fibers; (3) reducing body weight; and (4) exercising regularly (the 1-3-5-7 principle.). Exercise once a day for at least 30 minutes, at least five times a week, heart rate during exercise = 170 – age). For those who already have clear coronary heart disease, if the effect of non-pharmacological treatment is not good, or if they are already accompanied by hypertension, diabetes mellitus and other complications, they can reasonably choose and use lipid regulating drugs under the guidance of their doctors according to their personal characteristics, blood lipid levels, and the risk factors they have.
