Abstract

To assess the importance of postprandial lipemia and delayed chylomicron clearance as early atherogenic risk factors, 60 male offspring of parents with early coronary artery disease (CAD) and 41 controls were administered a fat-rich meal containing vitamin A. There were no significant differences between CAD-positive (CAD+) offspring and CAD-negative controls for areas under the postprandial curves for triglyceride and plasma, chylomicron, and chylomicron remnant retinyl palmitate. Older CAD+ offspring, aged 31-45 yr, had significantly increased very low density lipoprotein (VLDL) cholesterol, VLDL triglyceride, VLDL apoprotein B, and areas under postprandial curves for triglyceride and plasma, chylomicron, and chylomicron remnant retinyl palmitate than younger CAD+ offspring, aged 15-30 yr. Correcting for waist/hip ratio eliminated significant differences between the two groups for VLDL and areas under the triglyceride and chylomicron remnant curves, but this was not the case for the insulin sensitivity index. We conclude that neither increased postprandial lipemia nor abnormalities of chylomicron clearance are important early atherogenic risk factors in this population. An increase in age is associated with increased VLDL and...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.
