红细胞分布宽度对急性冠脉综合征患者的预后价值

目的 研究红细胞分布宽度(RDW)对急性冠脉综合征(ACS)患者预后的价值.方法 搜集本院2008年5～12月143例因急性冠脉综合征住院的患者,并进行冠状动脉造影以明确诊断.根据入院24h的首次红细胞分布宽度,按照其中位数将患者分成二组(RDW＜13.1%和RDW≥13.1%),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、死亡等不良心血管事件有无差别.结果 RDW≥13.1%组发生再次心肌梗死、新发心力衰竭、心源性死亡的比例高于RDW＜13.1%组,差异均具有统计学意义(P＜0.05).结论 RDW值对急性冠脉综合征预后有一定价值,RDW较高的急性冠脉综合征患者预后较差.

The predictive value of red cell distribution width in acute coronary syndrome

Objective To evaluate the predictive value of red cell distribution width in acute coronary syndrome. Methods 143 patients with acute coronary syndrome confirmed by coronary angiography were selected. They were hospitalized in the first affiliated hospital of Suzhou university from May 2008 to December 2008. According to RDW measured for the first time in 24 hours, the patients were divided into two groups： lower group （RDW 〈 13. 1% ） and higher group （RDW≥13.1% ）. The incidence of myocardial infarction, new heart failure and death between the two groups were cmpafied when they were hospitalized and diseharged in one year. Results Patients in higher group （RDW≥13.1%） had a higher incidence for cardiovascular events, compared with those in lower group （ RDW 〈 13.1% ） . And the difference were statistically significant （ P 〈0. 05 ）. Conclusions We found a correlation between higher levels of RDW and the risk of death and cardiovascular events in people with ACS.
