Background: Postprandial hypertriglyceridemia is a risk factor for atherosclerotic disease. However, the postprandial triglyceride (PTG) concentration fluctuates markedly and is poorly reproducible. The aim of this study was to determine whether the mean PTG (mean-PTG) concentration is a risk factor for carotid atherosclerosis in patients with type 2 diabetes. Methods: We measured the fasting and postprandial lipid concentrations, and the maximum intima-media thickness (max IMT) of carotid arteries by ultrasound in 115 diabetic patients. A carotid plaque was defined as max IMT of >1.0 mm. The mean-PTG concentration was calculated from several PTG concentrations measured on different days during a 1-year follow-up period. Results: PTG concentrations showed marked intra-individual variability, and ranged from 0.29 to 6.03 mmol/l. Patients with carotid plaques had higher mean-PTG concentrations than those without carotid plaques (1.51 +/- 0.57 vs. 1.29 +/- 0.47 mmol/l,p = 0.025). Neither fasting triglycerides nor one-point PTG concentrations differed between the two groups. Multivariate stepwise logistic regression analysis revealed that the mean-PTG concentration was significantly associated with carotid plaques [OR 1.20 (95% CI, 1.05-137), p = 0.009], even after adjusting for traditional risk factors including HDL-cholesterol, LDL-cholesterol, age, hypertension, and duration of diabetes. Conclusions: The mean-PTG concentration is an independent risk factor for carotid atherosclerosis in patients with type 2 diabetes. (C) 2013 Elsevier B.V. All rights reserved.
