IRA开通时间与再灌注心律失常相关性分析

Correlation analysis of IRA turn-on time and reperfusion arrhythmia

目的：回顾性分析急性心肌梗死（ AMI ）梗死相关血管（ IRA ）开通时间与再灌注心律失常（ RA ）相关性。方法行直接PCI治疗的患者70例，根据发病至IRA开通时间段分为3组：4 h内组24例，4～8 h组27例，8 h以上组19例。分别比较各组PCI术后再灌注心律失常发生、处理及转归。结果共44例患者发生RA。发病4 h内开通IRA组，RA发生率及快速性心律失常总体发生率与其他两组相比P＜0.01，室性早搏发生率与8 h以上组比较P＜0.05，心室颤动发生率与其他两组比较，P＜0.05。结论 AMI患者发病至开通IRA时间与再灌注心律失常明确相关。

Objective To retroepectively analyse the correlation between infarction related artery（IRA）tum-on time of acute myocardial infarction（AMI）and reperfusion arrhythmia.Methods 70 patients with AMI undergoing direct PCI treatment were divided into 3 groups according to the IRA turn-on time after invasion：group of 24 cases within 4 hours, group of 27 cases within 4 to 8 hours, and group of 19 cases over 8 hours）.Reperfusion arrhythmia occurrence ,disposal ,prognosis after PCI treatment among the three groups were respectively compared.Results Totally 44 cases showed RA.The incidence rate of RA and the overall incidence rate of tachyarrhythmia in the first group showed P〈0.01 compared with the other two groups;the incidence rate of ventricular premature beat in the first group showed P〈 0.05 compared with the third group; the incidence rate of ventricular fibrillation in the first group showed P 〈 0.05, compared with the other two groups.Gonclusion The IRA turn-on time after invasion among the AMI sufferers is definitely correlated to reperfusion arrhythmia.
