  • Title: Lipid and apolipoprotein ratios: association with coronary artery disease and effects of rosuvastatin compared with atorvastatin, pravastatin, and simvastatin.

    Abstract:
    Plasma lipid and apolipoprotein ratios that include both an atherogenic and an antiatherogenic lipid component (eg, total cholesterol/high-density lipoprotein [HDL] cholesterol ratio, low-density lipoprotein [LDL] cholesterol/HDL cholesterol ratio, non-HDL cholesterol/HDL cholesterol ratio, and apolipoprotein [apo] B/apo A-I ratio) have been found to be strong predictors of coronary artery disease (CAD) risk. Three trials that compared the effects of rosuvastatin 10 mg versus atorvastatin 10 mg and 2 trials that compared the effects of rosuvastatin 10 mg versus simvastatin 20 mg and pravastatin 20 mg on lipid ratios in patients with hypercholesterolemia were prospectively designed for pooled analysis. At 12 weeks, in the 3-trial pooled analysis, rosuvastatin 10 mg (n = 389) showed significantly greater reductions in all 4 lipid ratios compared with atorvastatin 10 mg (n = 393) (p <0.001). The mean percent reduction from baseline in the LDL cholesterol/HDL cholesterol ratio was 51% in patients treated with rosuvastatin 10 mg versus 39% in patients treated with atorvastatin 10 mg. In the 2-trial pooled analysis, treatment with rosuvastatin 10 mg (n = 226) also resulted in significantly greater reductions in all 4 lipid ratios compared with both simvastatin 20 mg (n = 249) and pravastatin 20 mg (n = 252) (p <0.001). Mean percent reductions from baseline in the LDL cholesterol/HDL cholesterol ratio were 52%, 39%, and 30% for rosuvastatin 10 mg, simvastatin 20 mg, and pravastatin 20 mg, respectively, in these 2 trials.
