LDL 3.4 may require lipid-lowering drugs. Whether or not lipid-lowering drugs are required depends on the patient’s specific condition. 1. If the patient does not have other underlying diseases such as hypertension, diabetes mellitus and other test results such as HDL, triglyceride, cholesterol, cardiac ultrasound etc. are normal and the risk of coronary heart disease is low, he/she may not take lipid-lowering drugs orally, but can lower the lipid level by improving the life style such as low-fat diet and moderate exercise, and he/she can be rechecked in about 3 months. 2. If the patient is older, has general vascular condition, has atherosclerosis or plaque formation, or has combined with hypertension, angina, etc., he/she needs to take oral lipid-lowering drugs, such as atorvastatin, etc., to prevent the occurrence of coronary heart disease. Low-density lipoprotein is high, it is recommended to go to a regular hospital, under the guidance of a physician to standardize reasonable lipid lowering, so as not to delay the condition.
