According to the current standard of blood lipid, LDL 3.65mmol/L is higher than normal value, which is borderline elevated. The reference value of LDL is different according to different laboratory methods; according to China’s guidelines for prevention and treatment of dyslipidemia, the appropriate range of LDL is <3.37mmol/L, the borderline elevated value is 3.37~4.13mmol/L, and the elevated value is more than 4.14mmol/L. According to this standard, LDL 3.65mmol/L is a borderline elevated value. LDL is a class of plasma lipoproteins, and the blood lipids checked clinically include cholesterol, triglycerides, HDL and LDL. Increased LDL has been found to be a risk factor for atherosclerosis, which may cause coronary heart disease, stroke and other diseases. If elevated blood lipids are found, it is recommended to improve electrocardiogram, echocardiogram, carotid ultrasound, cardiovascular CT and other screenings to check whether vascular diseases are combined; it is recommended to quit smoking and alcohol, moderate exercise, regular work and rest, and keep a happy mood; it is necessary to choose lipid-lowering drugs, such as Rosuvastatin, if necessary, according to the results of blood lipid tests; and regular blood lipid tests to monitor the control level.
