摘要 目的观察经皮冠状动脉介入治疗(percutaneous transluminal coronary intervention,PCI)急性心肌梗死(acute myocardial infarction,AMI)合并完全性右束支传导阻滞(complete right bundle-branch block,CRBBB)患者的疗效。方法 64例AMI合并CRBBB患者分为3组,A组16例,在发病3h内进行急诊PCI;B组20例,在发病6h内进行急诊链激酶150万单位静脉溶栓治疗;C组28例,进行内科保守治疗。观察冠状动脉病变特点,比较3组患者入院4周内并发症发生率和入院4周内死亡率。结果冠状动脉造影显示均为左冠状动脉病变,70%为左前降支近端病变,30%为左主干病变,均在第一室间隔支发出之前发生梗死,狭窄程度在85%～95%,且有多发斑块形成。A组和B组患者并发症发生率无统计学差异(50.00%vs65.00%),均低于C组(92.86%)。B组和C组患者住院4周的死亡率无统计学差异(80.00%vs89.29%),均高于A组(43.75%)。结论急诊PCI是AMI合并CRBBB患者的首选治疗方法,可以减少并发症,降低近期死亡率。
