In China, myocardial infarction/ischemic heart disease has become the second cause of death and poses a great threat to the health of the population. And hyperlipidemia as a cardiovascular risk factor is an important controllable factor. However, since hyperlipidemia may not have obvious symptoms, it is mostly detected by physical examination. Chinese guidelines for lipid management suggest that people aged 20 to 40 can have their blood lipids checked once every five years; men over 40 and postmenopausal women are to be checked once a year; people with cardiovascular risk factors, such as hypertension and diabetes, and those with family history should also be checked once a year. Patients with acute coronary syndrome or atherosclerotic cardiovascular disease should be checked after admission to hospital, and those with combined risk factors should be checked once every six months. When elevated lipids are detected, lifestyle interventions and medications are needed. Statins are the drugs of choice and can be of great benefit to patients, and should be taken under the guidance of a physician. If you stop taking statins, cholesterol synthesis will resume and your blood lipids will rise to the same level as before you took the medication. 2. Pay attention to monitoring liver function and muscle pain when taking the drug. 3. If there is no contraindication, the longer the statin is taken, the more benefit it will bring.
