摘要

目的探讨急性前壁心肌梗死合并右束支阻滞(RBBB)的临床特点。方法回顾性对比分析2016年5月至2021年6月在我院住院治疗的急性前壁心肌梗死合并与不合并右束支阻滞的患者的临床经过、心电图和预后。结果观察组为急性前壁心肌梗死合并右束支阻滞患者

共有81例

其中48例为急性ST段抬高型心肌梗死

33例为急性非ST段抬高型心肌梗死

前降支近段急性闭塞59例

对照组为急性前壁心肌梗死不合并右束支阻滞者

共有526例

其中365例为急性ST段抬高型心肌梗死

161例为急性非ST段抬高型心肌梗死

住院期间死亡率和主要心脏不良事件发生率观察组均要高于对照组。结论急性前壁心肌梗死合并右束支阻滞往往提示前降支近段急性闭塞

心肌坏死面积大

血流动力学往往不稳定

住院期间心脏不良事件发生率要高于急性前壁心肌梗死不合并右束支阻滞者。前降支开口齐头闭塞也不一定导致新发右束支阻滞。

Abstract

Objective To explore the clinical characteristics of the patients with acute anterior myocardial infarction with right bundle brunch block. Methods Retrospectively comparative analysis the clinical characteristics

ECG and prognosis of the patients with acute anterior myocardial infarction with and without right bundle brunch block in our hospital from May 2016 to June 2021. Results The observe group were the patients with acute anterior myocardial infarction with right bundle brunch block

including 48 patients with ST segment elevation acute myocardial infarction and 33 patients with non-ST segment elevation acute myocardial infarction. There were 59 cases of acute complete occlusion in the proximal descending branch. The control group were the patients with acute anterior myocardial infarction without right bundle brunch block

including 365 patients with ST segment elevation acute myocardial infarction and 161 patients with non-ST segment elevation acute myocardial infarction. The mortality in-hospital and the major adverse cardiac events in the observe group were higher than those in the control group.Conclusions Acute anterior myocardial infarction with right bundle brunch block often indicates the occlusion in the proximal anterior descending branch

the large area of myocardial necrosis

the unstable hemodynamics

and the mortality and major adverse cardiac events during hospitalization are higher than those in the control group. The occlusion of the ostium anterior descending artery does not necessarily lead to right bundle branch block.
