Total cholesterol of 6.9mmol/L is considered to be hyperlipidemic and should be treated with dietary control and oral statin lipid-lowering drugs if necessary. The normal value of total cholesterol is 0~5.7mmol/L. 6.9mmol/L exceeds the normal value and is considered hypercholesterolemia, which requires intervention. Patients with elevated cholesterol should first control their diet by strictly limiting the intake of high-fat foods, such as eating less animal fat, animal offal and other foods, eating more vitamin-rich vegetables, and limiting high-calorie foods. Patients with markedly elevated cholesterol also need to be given medication, commonly used drugs are mainly statin drugs, such as atorvastatin, resuvastatin, etc. Patients with combined cardiovascular and cerebral vascular diseases need long-term oral statin drug therapy. Patients with hypercholesterolemia should be treated under the guidance of a physician, and should be reviewed regularly during treatment, while paying attention to the adverse effects of drugs.
