Hyperlipidemia is not an indicator, but a number of indicators, including total cholesterol, triglycerides, LDL, HDL indicators, of which except for the last indicator, the other three indicators are elevated to indicate elevated blood lipids. The general reference value of blood lipids is: serum total cholesterol level should be lower than 5.2mmol/L, serum triglyceride level should be lower than 1.70mmol/L, serum LDL level should be lower than 3.1mmol/L, serum HDL level should be higher than 1.2mmol/L. Among them, except for HDL which is beneficial to human body and is known as the scavenger of the blood vessels, the other ones should be strictly controlled. Lipid indexes should be strictly controlled. For some patients with high risk factors, lipid control should be more stringent, such as atherosclerotic plaque patients should have LDL levels below 1.8mmol/L, and hypertensive patients should have LDL levels below 2.6mmol/L. If elevated blood lipids are found, please follow the doctor’s instructions to improve the relevant examination and treatment.
