AIM: Information about the effects of HMG-CoA reductase inhibitor (statin) treatment on lipoprotein subclasses has been severely limited. Nuclear magnetic resonance (NMR) spectrometry has emerged as a new methodology to quantify lipoprotein subclass concentrations. In the present study, we attempted to evaluate the hypolipidemic effects of atorvastatin utilizing this method. METHODS: Twenty-six patients were administered with atorvastain 10 mg daily for 4 weeks. Lipoprotein subclasses were measured by nuclear magnetic resonance (NMR) spectroscopy. Inflammation markers, including C-reactive protein (CRP), interleukin-6 (IL-6), and monocyte chemotactic protein-1 (MCP-1), were also determined. RESULTS: Additional to a marked reduction of LDL-C (-43%), atorvastatin treatment significantly decreased TG, RLP-C, apoC-II, apoC-III, and apoE by 27%, 49%, 25%, 15%, and 28%, respectively. NMR analysis revealed marked reductions of all LDL subclasses, resulting in a significant reduction of LDL particle number as well as an increase in LDL particle size. Further, some VLDL were decreased and HDL particle size was increased by atorvastatin. Among inflammation markers, MDA-LDL and IL-6 were marginally to significantly decreased. CONCLUSION: In addition to a strong LDL-C lowering function, atorvastatin exerts beneficial effects on TG-rich lipoproteins and inflammation in hypercholesterolemic patients.
