Abstract: The purpose of the following study was to investigate the physiological mechanisms underlying the diverging impact of two statins (HMG-CoA reductase inhibitors) widely used in clinic, simvastatin and atorvastatin, on high density lipoprotein cholesterol (HDL-C). To do so, we compared the impact of the two lipid-lowering agents on apoA-I kinetics, the protein moiety of HDL, in 7 hypercholesterolemic men with low HDL levels. All subjects were assigned two both treatments, simvastatin 80 mg/day and atorvastatin 40mg/day, in a randomized, cross-over, double-blind fashion. Each treatment phase last 8 weeks and kinetic studies were performed at the end of each treatment phase. Our analysis has demonstrated that simvastatin 80 mg/day was associated with a significant 8% greater apoA-I concentration in circulation compared to atorvastatin 40 mg/day. The higher apoA-I conentration observed with simvastatin 80 mg/day was explained by a significant 15% greater aspoA-I production rate with simvastatin 80 mg/day compared to atorvastatin 40 mg/day.
