The normal value of LDL is 0 to 3.37 mmol/L. Reaching 4.0 mmol/L exceeds the normal value, and the severity should be assessed for cardiovascular disease risk, and treatment should be given according to the level of risk. Elevated LDL alone, no medication is needed, it can be controlled by lifestyle, limiting the intake of high-fat foods, eating more vegetables, and strengthening exercise. Patients with elevated LDL who have multiple risk factors, such as smoking, family history of early-onset cardiovascular disease, and the presence of cardiovascular disease, are at high risk, and need oral medication, such as atorvastatin and resuvastatin, to lower the level of LDL to less than 1.8 mmol/L on the basis of dietary control. Patients with elevated LDL are evaluated for risk and a specific treatment plan is developed under the supervision of a physician.
