Serum C1q/TNF-Related Protein-2 (CTRP2) Levels are Associated with Coronary Artery Disease.

Recent studies have shown that complement C1q tumor necrosis factor related proteins (CTRPs) such as adiponectin, have different regulatory roles on the cardiovascular system. CTRP2 is the most similar to adiponectin and one of the best characterized beneficial adipokines important in the regulation of whole body metabolism. However, there were no studies about the relationship between CTRP2 and Coronary artery disease (CAD). This study aimed to evaluate the serum CTRP2 levels in patient with Coronary artery disease. In this study, a total of 82 participants who underwent vascular angiography were included. All of subjects were male. According to their coronary angiography results, all participants were divided into CAD group (n = 42) and control group (n = 40). Serum CTRP2 levels were determined quantitatively with enzyme-linked immunosorbent assay (ELISA). Our study for the first time showed that the CTRP2 levels were higher in CAD patients (1.79 ± 1.46 ng/mL) compared to control subjects (1.08 ± 0.78 ng/mL; p = 0.001). The levels of CTRP2 also were positively correlated with severity of CAD (r = 0.356, p = 0.001). In addition, logistic regression analysis indicated that CTRP2 had an independent association with the risk of CAD (OR [CI] = 3.366 [1.605-7.060]; p = 0.001). Increased levels of CTRP2 in CAD patients were independently associated with the progression of the CAD, it might be regarded as a novel biomarker for assessing the risk of CAD; however, more study is required in this regard.
