Abstract
Background— High-sensitive C-reactive protein (hs-CRP) is a well-known risk factor for coronary artery disease (CAD). Recently, we have demonstrated that adiponectin served as an antiatherogenic plasma protein which was secreted specifically from adipocytes. The present study investigated the association between adiponectin and CRP in the blood stream and adipose tissue. Methods and Results— We studied a total of 101 male patients, 71 of whom had angiographically documented coronary atherosclerosis. As a control group, 30 patients with normal coronary angiogram were included. The plasma hs-CRP levels were negatively correlated with the plasma adiponectin levels (r=−0.29, P<0.01). The plasma adiponectin concentrations were significantly lower and the hs-CRP levels were significantly higher in the CAD patients compared with control subjects. The mRNA levels of CRP and adiponectin were analyzed by quantitative real-time polymerase chain reaction method. We found that the CRP mRNA was expressed in human adipo...
