非ST段抬高型心肌梗死患者红细胞分布宽度与冠状动脉侧支循环的关系

Correlation between red blood cell distribution width and coronary collateral circulation in patients with non-ST elevation myocardial infarction

目的:研究非ST段抬高型心肌梗死(NSTEMI)患者的冠状动脉侧支循环(CCC)形成与红细胞分布宽度(RDW)的关系。方法:选取南阳市中心医院和河南省人民医院心内科NSTEMI患者120例,采用Retrop分级方法,对CCC进行分级,分为CCC不良组(70例)和CCC良好组(50例)。RDW值采用全自动血细胞分析仪测定。结果:CCC不良组RDW水平显著高于CCC良好组(P<0.05)。多因素Logistic回归分析显示RDW、肌酸激酶同工酶(CK-MB)、无梗死前心绞痛是不良CCC的独立预测因素。结论:在NSTEMI患者中,高RDW,高CK-MB、无梗死前心绞痛是不良CCC的独立预测因子。

Objective：To study the correlation between the red blood cell distribution width（RDW）and coronary collateral circulation（CCC）in patients with non-ST elevation myocardial infarction（NSTEMI）.Method：The120patients with NSTEMI from department of cardiology in our hospital and Henan Provincial People＇s Hospital were divided into impaired CCC group（n=70）and good CCC group（n=50）according to Retrop classification method for grading CCC.RDW value was measured by automatic blood cell analyzer.Result：RDW values were significantly higher in patients with impaired CCC than in those with good CCC（P〈0.05）.In multivariate logistic regression analysis,RDW,CK-MB,absence of preinfarction angina were found to be the independent predictors of impaired CCC.Conclusion：In NSTEMI,high RDW,high CK-MB,absence of preinfarction angina were found to be independent predictors of impaired CCC.
