红细胞分布宽度对行急诊PCI的ACS患者的预后价值

目的 研究红细胞分布宽度(RDW)与行急诊经皮冠状动脉介入治疗(PCI)的急性冠脉综合征(ACS)患者预后的关系.方法 搜集本院2009年1～8月116例因ACS入院并行急诊PCI术的患者资料,根据入院24 h首次RDW中位数(12.8%)检测结果,将患者分为RDW≥12.8%和RDW＜12.8%组,观察其住院期间及出院1年内发生心肌缺血、心力衰竭、心源性死亡等心血管不良事件的差别.结果 共纳入符合条件ACS患者116例,在校正血红蛋白含量(Hb)、平均红细胞体积(MCV)、性别、年龄、高血压、糖尿病等因素影响后,RDW升高仍是行急诊PCI术的ACS患者住院期间及出院1年内发生心血管不良事件的危险因素.结论 RDW值对行急诊PCI术的ACS患者预后有一定价值;RDW较高患者,其住院期间及出院1年内预后较差.

Prognostic value of red blood cell distribution width in patients with acute coronary syndrome receiving emergency percutaneous coronary intervention

Objective To investigate the correlation between the red blood cell distribution width（RDW）and the prognosis of patients with acute coronary syndrome（ACS）who received the emergency percutaneous coronary intervention（PCI）.Methods The data of 116 patients hospitalized for ACS and undergoing emergency PCI from January to August,2009 were collected.According to the detection results of median RDW（12.8%）the first time in 24 h after the admission,these patients were divided into two groups（RDW≥12.8%and RDW12.8%）.Comparison was made in the occurrence of myocardial ischemia,heart failure and cardiac death between the two groups in hospital period and 1 year after the discharging.Results After the correction of influencing factors such as hemoglobin level,mean corpuscular volume,sex,age,hypertension and diabetes,the increase of RDW was still the risk factor causing the occurrence of adverse cardiovascular events in ACS patients receiving emergency PCI in the duration of hospital and within 1 year after the discharging.Conclusion The RDW is valuable in the prognosis of ACS patients receiving emergency PCI.Those patients with high RDW have bad prognosis in the duration of hospital and within 1 year after the discharging.
