红细胞分布宽度对冠心病患者预后的价值研究

目的探讨红细胞分布宽度(RDW)对冠心病(CAD)患者预后的价值。方法收集本院2008年3月—2010年5月155例因CAD住院的患者,并进行冠状动脉造影以明确诊断。根据入院24h的首次RDW,按照其中位数(13.7%)将患者分为两组:A组(RDW≤13.7%,n=78)和B组(RDW>13.7%,n=77),比较两组患者住院期间及出院1年内发生再次心肌梗死、新发心力衰竭、心源性死亡等不良心血管事件的差异。结果 B组发生再次心肌梗死、新发心力衰竭、心源性死亡发生率均高于A组,差异有统计学意义(P<0.05)。结论 RDW对CAD预后有一定价值,RDW水平较高的CAD患者预后较差。

The Prognosis Effects of the Red Blood Cell Distribution Width with Coronary Artery Disease

Objective To evaluate the predictive value of red cell distribution width(RDW)in coronary artery disease(CAD).Methods A total of 155 patients with CAD confirmed by coronary angiography were selected.They were hospitalized in the First People′s Hospita1 of Chuzhou from March 2008 to May 2010.According to the RDW measured(13.7%)for the first time in 24 hours,the patients were divided into two groups:group A(RDW≤13.7%,n=78)and group B(RDW>13.7%,n=77).The incidence of myocardial infarction,new heart failure and death between the two groups were compared when they were hospitalized and discharged in one year.Results CAD patients in group B had a higher incidence for cardiovascular events,compared with those in the group A,and the difference were statistically significant(P<0.05).Conclusion There is a correlation between higher levels of RDW and the risk of death and cardiovascular events in people with CAD.
