The metabolic syndrome (MS) is a constellation of coronary risk factors. Atherogenic dyslipidemia is an important factor in cardiovascular risk in these patients, and treatment of atherogenic dyslipidemia has been identified as an important goal of therapy in patients with MS. This post hoc analysis of data from a 6-week, randomized, open-label, parallel-group, comparative trial (Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin [STELLAR]) assessed the effects of rosuvastatin 10, 20, and 40 mg, atorvastatin 10, 20, 40, and 80 mg, simvastatin 10, 20, 40, and 80 mg, and pravastatin 10, 20, and 40 mg on plasma lipids in hypercholesterolemic patients (low-density lipoprotein cholesterol >/=160 and <250 mg/dl; triglycerides <400 mg/dl) who had >/=3 of the 5 National Cholesterol Education Program Adult Treatment Panel III criteria for MS (body mass index >30 kg/m(2) substituted for waist circumference). Of 2,268 patients, 811 met criteria for MS. Percent reductions in low-density lipoprotein cholesterol ranged from 20% in the pravastatin 10-mg group to 55% in the rosuvastatin 40-mg group. In patients with MS, triglyceride reductions were 22% to 34% with rosuvastatin, 23% to 33% with atorvastatin, 15% to 23% with simvastatin, and 12% to 15% with pravastatin. High-density lipoprotein cholesterol increased by 8% to 11% with rosuvastatin, 5% to 9% with atorvastatin, 8% to 10% with simvastatin, and 3% to 7% with pravastatin. Rosuvastatin, atorvastatin, simvastatin, and pravastatin treatment had favorable effects in hypercholesterolemic patients on the atherogenic dyslipidemia associated with MS. Rosuvastatin had the most favorable effect on the atherogenic lipid profile of MS overall.
