The normal range of LDL is <3.4mmol/L. Therefore, LDL 3.38mmol/L does not necessarily require lipid-lowering drugs, but needs to be combined with whether the patient is combined with high-risk factors to determine. LDL is the "bad cholesterol" in the blood, and its elevation greatly increases the incidence of cardiovascular and cerebrovascular diseases, therefore, for patients with high-risk factors, the index should be strictly controlled. 1. Combined high-risk factors: For patients suffering from hypertension, diabetes, coronary heart disease, cardiac stenting, cerebral infarction, etc., when the LDL is 3.38mmol/L, they should take lipid-lowering drugs under the guidance of the doctor. 2. Without combining high-risk factors: For the general population without combining the above high-risk factors, LDL 3.38mmol/L is at the upper limit of the normal range, and this kind of people can control the further rise of blood lipids through diet and exercise. Warm reminder: LDL 3.38mmol/L does not necessarily need to take lipid-lowering drugs, combined with high-risk factors of the patient should be taken as soon as possible under the guidance of a doctor to lower the lipid drugs, during the period of time to monitor renal function and muscle enzymes.
