In fact, there are several commonly used lipid indicators. One is total cholesterol, the second is triglycerides, the third is high-density lipoprotein, and the fourth is low-density lipoprotein. The definition of hyperlipidemia, in fact clinically, is primarily characterized by elevated cholesterol and low-density lipoprotein levels. Some patients predominantly have elevated triglycerides. Therefore, these indicators need to be controlled in clinical practice. For example, total cholesterol, for diabetic patients, is generally required to be controlled below 4.5 mmol/L. For low-density lipoproteins, in people without coronary heart disease, it should be controlled below 2.6 mmol/L; for those with coronary heart disease as a high-risk factor, it should be controlled below 1.8 mmol/L.
