Objective Patients with metabolic syndrome (MetS) are at a high risk for developing atherosclerosis and cardiovascular disease. Serum levels of chemerin have been found elevated in subjects with MetS and are associated with several cardiovascular factors. This study was undertaken to determine whether serum chemerin levels are associated with coronary artery disease (CAD) in patients with MetS.
Methods A total of 112 patients with MetS (66 patients with CAD and 46 without CAD) and 52 healthy subjects who underwent coronary angiography for the evaluation of CAD were enrolled in this study. Serum levels of chemerin were measured by enzyme-linked immunosorbent assay.
Results Serum chemerin levels were significantly elevated in MetS patients with CAD compared to in those without CAD and healthy subjects. MetS patients without CAD also had higher serum chemerin levels compared with healthy subjects. Multivariate logistic regression analysis revealed that serum chemerin levels were significantly associated with the presence of CAD in patients with MetS. Simple linear regression analysis showed that the serum levels of chemerin were positively correlated with body mass index (BMI), systolic blood pressure (SBP), serum triglycerides and C-reactive protein (CRP) in patients with MetS. Only BMI and CRP remained significantly associated with serum chemerin after multiple stepwise regression analysis.
Conclusion Elevated serum chemerin levels could be considered as an independent predictive marker of the presence of CAD in patients with MetS.
