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.
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.
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.
Elevated serum chemerin levels could be considered as an independent predictive marker of the presence of CAD in patients with MetS.
代谢综合征(MetS)患者发生动脉粥样硬化和心血管疾病的风险很高。已发现MetS患者血清中chemerin水平升高,且与多种心血管因素相关。本研究旨在确定MetS患者血清chemerin水平是否与冠状动脉疾病(CAD)相关。
本研究共纳入112例MetS患者(66例CAD患者和46例无CAD患者)以及52例因评估CAD而接受冠状动脉造影的健康受试者。采用酶联免疫吸附测定法测量血清chemerin水平。
与无CAD的MetS患者及健康受试者相比,患有CAD的MetS患者血清chemerin水平显著升高。无CAD的MetS患者血清chemerin水平也高于健康受试者。多因素逻辑回归分析显示,血清chemerin水平与MetS患者CAD的存在显著相关。简单线性回归分析表明,MetS患者血清chemerin水平与体重指数(BMI)、收缩压(SBP)、血清甘油三酯和C反应蛋白(CRP)呈正相关。经过多步回归分析后,只有BMI和CRP仍与血清chemerin显著相关。
血清chemerin水平升高可被视为MetS患者CAD存在的独立预测标志物。
