There is controversy about the effects of statins on plasma adiponectin, and the impact of percutaneous coronary intervention (PCI) on plasma adiponectin level is still unknown. We investigated the impact of Atorvastatin on plasma adiponectin levels in coronary artery disease (CAD) patients with stable angina and normal lipid profiles after PCI.

Sixty CAD patients with stable angina and normal lipid profiles scheduled for PCI, and not on statins, were randomly assigned to either no treatment (control group) or the Atorvastatin treatment (Atorvastatin group). Atorvastatin administration was started immediately after PCI. Blood samples were obtained immediately after PCI and again 3 and 6 mo later. Fasting plasma adiponectin concentrations were measured using a radioimmunoassay kit.

After PCI, there were statistically significant decreases in adiponectin levels in the Atorvastatin group at 3 and 6 mo (8.66 +/- 0.69 versus 6.87 +/- 0.55 and 7.12 +/- 0.71 microg/mL at 0, 3, and 6 mo, respectively), despite the anti-inflammation and lipid-lowering effects of Atorvastatin. There were no statistically significant changes in adiponectin levels in the control group. There was significant positive association between baseline plasma adiponectin and high-density lipoprotein (HDL) levels. Changes of adiponectin level were not associated with the changes of high-sensitivity C-reactive protein (hs-CRP) and lipid profiles in the Atorvastatin group.

Our study confirmed the benefits of Atorvastatin on anti-inflammation and anti-atherosclerosis, but we also found that Atorvastatin had a negative effect on the adiponectin system. The anti-inflammatory, anti-atherogenic effects of Atorvastatin are not affected by decreased adiponectin levels.
