急性心肌梗死患者红细胞分布宽度与住院期间并发症发生的关系研究

Relationship between Red Blood Cell Distribution Width and Complications of Patients with Acute Myocardial Infarction during Hospitalization

目的探讨急性心肌梗死患者红细胞体积分布宽度(RDW)与住院期间并发症发生风险之间的关系方法采用巢式病例对照研究设计,对200例急性心肌梗死患者进行随访观察和配对病例对照研究,采用配对Logistics回归分析显示急性心肌梗死患者红细胞分布宽度与住院期间并发症发生的关系。结果急性心肌梗死患者住院时RDW越高,其并发症发生率也越高(χ2趋势=19.808);RDW与并发症发生风险之间存在正相关(OR=1.565)。结论早期检测RDW能预测急性心肌梗死患者住院期间并发症发生的风险,临床医生可据此积极做好预防措施。

Objective To explore the relationship between red cell volume distribution width（RDW） and the risk of complications during hospitalization in patients with acute myocardial infarction. Methods With nested case control study,200 patients with myocardial infarction were followed up and underwent matched case-control study.Matching logistics regression analysis was used to show the relationship between red cell distribution width and complications in patients with acute myocardial infarction during hospitalization. Results The higher the acute myocardial infarction RDW levels is,the higher the complication rate will be（χ2trend =19.808）.There was a positive correlation between RDW and the risk of complications（OR=1.565）. Conclusion Early detection of RDW can predict the risk of complications in patients with acute myocardial infarction during hospitalization,suggesting that clinicians should actively carry out preventive measures.
