目的：探讨急性心肌梗死（acute myocardial infarction，AMI）患者经皮冠状动脉介入（percutaneous coronary intervention，PCI）术与无复流的关系。方法对116例 AMI 患者，术前均给予阿司匹林300 mg、氯吡格雷300 mg等治疗，且急诊 PCI 术证实病变血管远端完全闭塞。其中 A 组59例，先用小球囊、低压力扩张后，闭塞血管远端部分恢复血流，后行支架植入术；B 组57例，先用小球囊、低压力扩张后，闭塞血管远端部分恢复血流，再用大球囊、高压力扩张后行支架植入术。结果 A 组发生无复流6例，B 组发生无复流14例。结论 AMI 患者病变血管经球囊多次、高强度扩张增加 PCI 术后无复流发生率，且球囊扩张强度越高，无复流的发生率可能越高。

Objective To investigate the relationship between acute myocardial infarction (AMI)patients with percutaneous coronary intervention (PCI)and no reflow.Methods One hundred and sixteen patients with AMI were given two grade coronary heart disease prevention and anticoagulation before operation.The culprit vessel distal occlusion was confirmed by surgery PCI.Fifty-nine patients with AMI in group A:the lesions were firstly dilated by small balloon and low pressure,then planted with stents.Fifty-seven in patients with AMI in group B:the lesions firstly dilated by small balloon and low pressure,then changing bigger balloon and high pressure dilated again,at last planted with stents.Results The incidence of no reflow in group A was 6 cases.The incidence of no reflow in group B 14 cases.Conclusion The balloon dilation number and expansion intensity in patients with AMI increase the incidence of no reflow.The more intensity the balloon dilation,the high the incidence of no reflow.
