3.71 mmol/L is recommended for LDL patients; since different people have different target goal values, it is necessary to determine the appropriate LDL on a case-by-case basis. Patients who are young and have no other risk factors should have an LDL target of 3.4 mmol/L or less, whereas excess LDL can lead to atherosclerosis, and early intervention is recommended to slow or reverse this process. Patients with existing atherosclerosis, such as coronary heart disease, cerebrovascular disease, lower limb vessels, renal artery stenosis or those who have already formed significant plaque, indicate that the patient is already in a high-risk state, and the LDL target is 1.8mmol/L or less. It is recommended that patients should not judge or diagnose on their own based on one result, but should consult a doctor in a timely manner, who will analyze the situation comprehensively and make a clear diagnosis according to the specific circumstances.
