Why the study?
Renewed interest in triglyceride-rich lipoproteins as causative agents in cardiovascular disease mandated further exploration of the integrated metabolism of chylomicrons and VLDL.
Population
15 subjects with a wide range of plasma triglyceride levels
Design
Metabolic tracer kinetic study with an integrated multi-compartmental model

Does not support changes in triglyceride management; extends kinetic modeling but leaves clinical translation open.
ApoB48-containing particles comprise about 20-25% of circulating VLDL and accumulate as slowly cleared remnants in individuals with elevated triglycerides, providing a metabolic mechanism for increased CHD risk.
Björnson et al. (2019) studied this question.
