冠心病患者血清脂联素、YKL-40水平的变化及其与冠状动脉病变程度的关系

目的:探讨冠心病患者血清脂联素、YKL-40水平的变化及其与冠状动脉病变程度和粥样硬化斑块稳定性的关系。方法:选取行冠状动脉造影者94例作为研究对象,根据冠状动脉造影结果结合临床病史分为正常对照组、稳定型心绞痛(SAP)组、不稳定型心绞痛(UAP)组和急性心肌梗死(AMI)组,根据冠状动脉病变血管数分为正常对照组、单支病变组、双支病变组、三支病变组,测定并比较各组血清脂联素、YKL-40水平。采用Gensini积分系统评定冠状动脉血管病变狭窄程度与脂联素、YKL-40的相关性。结果:AMI组、UAP组、SAP组血清脂联素水平均低于对照组(P<0.05~P<0.01),AMI组、UAP组低于SAP组(P<0.01),UAP组与AMI组差异无统计学意义(P>0.05)。AMI组、UAP组、SAP组血清YKL-40水平均高于对照组(P<0.05~P<0.01),AMI组、UAP组高于SAP组(P<0.01),UAP组与AMI组差异无统计学意义(P>0.05)。对照组、单支病变组、双支病变组、三支病变组血清脂联素水平依次降低,差异均有统计学意义(P<0.05~P<0.01),而血清YKL-40水平依次升高,差异亦均有统计学意义(P<0.05~P<0.01)。脂联素与Gensini积分呈负相关关系(P<0.01),YKL-40与Gensini积分呈正相关关系(P<0.01)。结论:血清脂联素和YKL-40水平与冠状动脉病变程度和粥样硬化斑块的不稳定性有关,病变越重、斑块不稳定者脂联素越低,而YKL-40水平越高。

Change of serum levels of adiponectin and YKL-40 in patients with different coronary heart diseases and its correlation with the severity of coronary artery lesion

Objective:To investigate the change of serum levels of adiponectin and YKL-40 in patients with different coronary heart diseases(CHD),and its relationship with the severity of coronary artery lesion and the stability of atherosclerotic plaque.Methods:Ninety-four patients undergoing coronary angiography were included in the study.According to the opacification results and clinical history,the patients were divided into normal control group,stable angina pectoris(SAP) group,unstable angina pectoris(UAP) group...
