摘要
目的了解伴随急性心肌梗死出现的完全性右束支传导阻滞的临床特点和预后意义。方法观察有新出现持续性完全性右束支传导阻滞的急性心肌梗死患者45例 (观察组 ) ,同期收治的无右束支传导阻滞的急性心肌梗死患者90例 (对照组 )的CK峰值、KilliP分级、严重心律失常发生率、LVEF和住院病死率的情况。结果观察组CK峰值 (2498±1369U/L) ,明显高于对照组 (1757±1026U/L) (P<0.05)。观察组Killip平均级别2.5±1.1 ,非常明显高于对照组 (1.7±0.9) ,(P<0.01)。观察组缓慢型心律失常及室性恶性心律失常发生率 (20%、16 % ) ,明显高于对照组 (4 %、4% ) (P均<0.05)。观察组的住院病死率 (15.6 % )显著高于对照组 (4.4% ) (P<0.05)。结论急性心肌梗死新出现的持续性完全性右束支传导阻滞提示临床病情危险 ,预后不良。
Objective To investigate clinical significance and prognosis of complete right bundle branch block(CRBBB) in patients suffering from acute myocardial infarction(AMI). Methods 45 patients with new persistent CRBBB complicated following AMI(n=45) admitted into our hospital were included(observation group,n=45),90 patients admitted in same period with AMI but without RBBB were used as control group(n=90).Admitted peak value of serum CK,degree of Killip,incidence of severe arrhythmias,LVEF and in_hospital mortality of all patients were analyzed. Results Peak value of serum CK in observation group(2498±1369 U/L) was significantly higher than that in control group(1757±1026 U/L)(P<0.05).Cardiac function was more severely damaged in observation group,average degrees of Killip were 2.5±1.1,significantly higher than that in control group(1.7±0.9)(P<0.01). Compared with control group, observation group showed increased incidence of bradyarrhythmia(20% vs.4%,P<0.05),severe ventricular arrhythmia(16% vs.4%,P<0.05) and increased in_hospital mortality(15.6% vs.4.4%,P<0.05).Conclusion New persistent CRBBB following AMI indicated severe clinical situation and poor prognosis.
