摘　　要：目的探讨PCI术后WBC与平均血小板体积比值(WMR)波动情况对于急性心肌梗死患者临床预后的预测价值。方法回顾性分析64例ST段抬高型急性心肌梗死(STEMI)患者临床资料,根据PCI术后2年主要心血管不良事件(MACE)发生情况,分为MACE组(28例)和非MACE组(36例)。比较PCI术前和术后2h WBC与WMR水平波动情况(△=术前-术后)与MACE发生的相关性。结果 PCI术后可见非MACE组患者WMR下降较为明显(P<0.05),而MACE组无明显改变(P>0.05)。MACE组△WMR明显低于非MACE组(P<0.05)。△WMR与术后2年MACE发生率呈负相关(r=-0.678,P<0.05)。结论 WMR水平改变有助于早期评估STEMI患者PCI术后MACE的发生风险。Objective To evaluate the application of white blood cell count to mean platelet volume ratio（WMR） in predicting major adverse cardiac events（MACE） of patients with acute myocardial infarction.Methods Sixty four ST-elevated myocardial infarction patients were divided into two group based on occurrence of MACE in 2 years：non-MACE group（n=28）and MACE group（n=36）.The fluctuation of WMR was analyzed before and after PCI treatment.Results The levels of WMR in non-MACE group were significantly decreased after PCI treatment（P〈0.05）,while there was no significant difference in WMR of MACE group before and after PCI.Correlation analysis showed that △WMR was negatively correlated with the occurrence of MACE in 2 years（r=-0.678,P〈0.05）.Conclusion Dynamic observation of WMR may be useful for predicting MACE in patients with acute myocardial infarction undergoing PCI.
