The role of ezetimibe and simvastatin in modulating intestinal cholesterol transport, chylomicron profile and chylomicron-remnant uptake by the arterial wall in a rodent model of the metabolic syndrome

  • Intestinally derived chylomicron remnants (CM-r) may contribute to atherogenic dyslipidemia during the Metabolic Syndrome (Mets). However, the combined effects of ezetimibe (EZ) and simvastatin (SV) on post-prandial (PP) dyslipidemia during MetS remains unclear, nor is it known whether the combination has a synergistic anti-atherogenic effect on CM-r arterial retention. The first objective was to delineate the effects of EZ+SV therapy on intestinal cholesterol flux and CM PP metabolism in the JCR:LA-cp rat, a model of MetS. The second objective was to quantify the impact of EZ+SV therapy on arterial retention of CM-r and subsequent myocardial lesion development in the JCR:LA-cp rat. EZ+SV therapy decreased net intestinal cholesterol absorption in MetS rats. Furthermore, EZ+SV therapy reduced arterial retention of CM-r and frequency of myocardial lesions in MetS rats. In conclusion, EZ+SV therapy reduces arterial retention of CM-r and myocardial lesion development possibly through its beneficial effects on cholesterol transport and PP-metabolism.
