急性心肌梗死患者红细胞分布宽度与其经皮冠状动脉介入术后梗死相关血管预后的相关性

摘要

目的 分析急性心肌梗死(AMI)患者红细胞分布宽度(RDW)与其经皮冠状动脉介入术(PCI)术后梗死相关血管预后的相关性.方法 选择2016年10月至2018年4月山西医科大学第一医院收治的238例AMI患者,检测其RDW值,并观察RDW与PCI术后发生梗死相关血管事件的相关性.结果 共有214例受试者完成了随访.RDW异常组梗死相关血管事件的发生率高于RDW正常组,差异有统计学意义(P<0.05).单因素相关性分析显示,RDW与再发心肌梗死、靶血管再次血运重建呈正相关(P<0.01);多元回归分析显示,PCI术后发生梗死相关血管事件的风险随RDW的升高而升高.结论 RDW异常的受试者梗死相关血管事件的发生率升高,且随RDW的升高而升高,因此RDW可以作为观察AMI患者PCI术后梗死相关血管预后的指标.%Objective To analyse the correlation between red blood cell distribution width ( RDW) and prognosis of infarct-related vessels in patients with acute myocardial infarction ( AMI) after percutaneous coronary intervention ( PCI) . Methods A total of 238 patients with AMI admitted to the First Hospital of Shanxi Medical University from October 2016 to April 2018 were selected. RAW was detected in all patients, the correlation of RDW and prognosis of blood vessel which was relative to infarct after PCI was analyzed. Results A total of 214 patients were followed up. The rate of blood vessel events in the RDW abnormal group was higher than the RDW normal group, and the difference between the two groups had statistical significance ( P<0. 05 ) . The analysis of single factor correlation showed that RDW was positively correlated with recurrence of myocardial infarction and target vessel revascularization ( P<0. 01 ) . The analysis of multiple regressions displayed that the risk of infarct-related blood vessel events after PCI would increase with the increase in RDW. Conclusions The rate of blood vessel events which are relative to infarct is higher in patients with abnormal RDW, and it increases as the RDW increases. So RDW could be as the predictive index for prognosis of infarct-related blood vessel of AMI patients after PCI.
