摘　　要：目的探讨心肌梗死(AMI)合并新发一过性右束支阻滞(RBBB)相关因素。方法收集AMI合并新发RBBB阻滞患者107例,根据RBBB是否院内消失将其分为新发持续RBBB组和新发一过性RBBB组。比较两组间的基线资料、院内预后;应用关联性分析研究AMI合并新发RBBB患者RBBB消失与接受接诊治疗时间相关性;应用Logistic回归筛选新发RBBB院内消失独立预测因素。结果与新发持续RBBB相比,新发一过性RBBB患者年龄、心功能受损程度及梗死面积相对较小,院内不良心脏事件(MACE)的发生率较低,且接受急诊介入治疗的比率较高;新发RBBB院内消失比率与急诊介入治疗时间呈负相关,Pearson相关系数r=-0.943;Logistic回归分析筛选新发RBBB院内消失与年龄、心肌酶峰值、Killip分级≥2呈负相关,与接受急诊介入治疗呈正相关。结论 AMI合并一过性RBBB较持续RBBB预后较好,新发RBBB院内消失比率与急诊介入治疗存在明显相关性。Objective To explore the related factors of new transient RBBB in AMI patients. Methods A total of 107 AMI patients combined new RBBB block patient were collected retrospectively, divided them into new onset permanent RBBB group and new onset transient RBBB group. Baseline data and in - hospital prognosis were compared between the two groups. Correlation analysis was used to analyze the relation between new RBBB disappearance rate and the time pa- tients received emergency coronary interventional treatinent. Logistic regression analysis was used to screen the inde- pendent predictors of new onset transient RBBB. Results Compared with the new permanent RBBB, new transient RBBB patients are younger, have better heart function, less infarction area, lower incidence of in - hospital MACE e- vents and higher rates of emergency interventional therapy. The in - hospital disappeared rate of new RBBB has negative- ly correlated with emergency interventional therapy time, r = - 0. 943. The disappeared rate of new RBBB has negative correlation with age, the myocardial enzyme peak and Killip＇ s classification =〉 2 , but has positive correlation with emer- gency interventional therapy. Conclusion New onset transient RBBB ＇ s in - hospital prognosis is better than that of new onset permanent RBBB. The disappeared rate of new RBBB has obvious correlation with emergency interventional therapy.
