Postprandial triglyceridemia, specifically plasma triglycerides at 2 hours, was independently associated with common carotid intima-media thickness in healthy middle-aged men (P<0.01).

Does postprandial triglyceridemia correlate with common carotid intima-media thickness in healthy middle-aged men?
Postprandial triglyceridemia is an independent predictor of early atherosclerosis, as measured by carotid intima-media thickness, in healthy middle-aged men.
p-value: p=<0.01
BACKGROUND: Alimentary lipemia has been associated with coronary heart disease and common carotid artery intima-media thickness (IMT). This study was designed to investigate the relations of subclasses of postprandial triglyceride-rich lipoproteins (TRLs) with IMT. METHODS AND RESULTS: Ninety-six healthy 50-year-old men with an apolipoprotein (apo) E3/E3 genotype underwent an oral fat tolerance test and B-mode carotid ultrasound examination. The apo B-48 and apo B-100 contents of each fraction of TRLs were determined as a measure of chylomicron remnant and VLDL particle concentrations. In the fasting state, LDL cholesterol (P<0.05) and basal proinsulin (P<0. 05) were significantly related to IMT, whereas HDL cholesterol, plasma triglycerides, and insulin were not. In the postprandial state, plasma triglycerides at 1 to 4 hours (P<0.01 at 2 hours), total triglyceride area under the curve (AUC) (P<0.05), incremental triglyceride AUC (P<0.01), and the large VLDL (Sf 60 to 400 apo B-100) concentration at 3 hours (P<0.05) were significantly related to IMT. Multivariate analyses showed that plasma triglycerides at 2 hours, LDL cholesterol, and basal proinsulin were consistently and independently related to IMT when cumulative tobacco consumption, alcohol intake, waist-to-hip circumference ratio, and systolic blood pressure were included as confounders. CONCLUSIONS: These results provide further evidence for postprandial triglyceridemia as an independent risk factor for early atherosclerosis and also suggest that the postprandial triglyceridemia is a better predictor of IMT than particle concentrations of individual TRLs.
Boquist et al. (1999) conducted a cross-sectional in Healthy (n=96). Postprandial triglyceridemia was evaluated on Common carotid artery intima-media thickness (IMT) (p=<0.01). Postprandial triglyceridemia, specifically plasma triglycerides at 2 hours, was independently associated with common carotid intima-media thickness in healthy middle-aged men (P<0.01).
