The normal range for LDL cholesterol should be under 3.4 mmol/L. The patient is grossly out of the normal range. Medication is needed. Excessive LDL will enter the patient’s vascular endothelial cells, which are phagocytosed by macrophages and gradually form atherosclerotic plaques. When the plaque is large, it will cause narrowing of blood vessels, resulting in insufficient blood supply. Plaque rupture will cause sudden and complete occlusion of blood vessels, local tissue ischemia and necrosis, such as cerebral infarction, myocardial infarction and so on. Therefore, patients need to lower LDL through drugs to prevent atherosclerosis. Patients can consult a doctor in time and take lipid-lowering drugs such as Rosuvastatin and Atorvastatin under the doctor’s guidance.
