In diabetic patients, if there is no combination of Atherosclerotic Cardiovascular Disease (ASCVD), LDL should be controlled below 2.6mmol/L; if there is combination of ASCVD, LDL should be controlled below 1.8mmol/L. Predisposing factors of atherosclerosis, such as obesity, hypertension, dyslipidemia, etc., are significantly higher in diabetic population, resulting in higher prevalence of atherosclerosis in diabetic population, earlier onset of the disease, and faster progression of the disease. Regular monitoring of LDL in diabetic patients can help to recognize the risk of atherosclerosis at an early stage, and can also be used as an indicator to assess the effectiveness of lipid-lowering drugs. If there is no combination of ASCVD, LDL generally needs to be controlled below 2.6mmol/L; if there is a combination of ASCVD, generally needs to be controlled below 1.8mmol/L. It is recommended that diabetic patients go to regular hospitals for timely consultation.
