Abstract

The atherogenicity of triglyceride-rich lipoprotein has been revealed. This study was performed to explore the clinical importance of triglyceride-rich lipoprotein by measuring its cholesterol content and comparing it with other lipoprotein fractions. Blood samples were obtained from 103 patients whose fasting plasma triglyceride concentration exceeded 300 mg/dl. The cholesterol monitor using the technique of high-performance liquid chromatography was used for the measurement of their plasma cholesterol concentrations and the determination of cholesterol distribution among lipoprotein fractions. This monitor showed 4 peaks: large-triglyceride-rich lipoprotein, small-triglyceride-rich lipoprotein, low-density lipoprotein, and high-density lipoprotein. Total cholesterol increased with increasing triglyceride. The increment of total cholesterol was nearly equal to that of small-triglyceride-rich lipoprotein cholesterol. Small-triglyceride-rich lipoprotein cholesterol exceeded low-density lipoprotein cholesterol where plasma triglyceride concentration was over 500 mg/dl. In conclusion, triglyceride-rich lipoprotein may be clinically important for hypertriglyceridemic patients as a source of cholesteryl ester in arteriosclerotic pla...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
