All of the following patients with diabetes, regardless of baseline lipid levels, should be treated with statins based on lifestyle interventions: 1. With definite cardiovascular disease, the LDL-C control goal is <1.8 mmol/L. 2. Without cardiovascular disease, but older than 40 years and with one or more risk factors for cardiovascular disease (family history of early-onset cardiovascular disease, smoking, hypertension The LDL-C control goal is LDL-C <2.6 mmol/L. 3. In low-risk patients (e.g., without definite cardiovascular disease and under 40 years of age), if the patient has LDL-C >2.6 mmol/L or multiple cardiovascular disease risk factors, statin therapy should be considered on the basis of lifestyle interventions. The control target for LDL-C is <2.6 mmol/L. In short, the target values for lipid lowering in diabetes mellitus are 2 main points: 1) lowering LDL-C levels as the primary target of intervention to prevent and control the risk of ASCVD; 2) there are target values for lipid regulating therapy: the control target for LDL-C in diabetes mellitus with a history of cardiovascular disease is <1.8 mmol/L, and the control target for LDL-C in diabetes mellitus without a history of cardiovascular disease is <2.6 mmol/L. is <2.6 mmol/L.
