急性心肌梗塞再灌注损伤临床表现及分析

Clinical manifestation of reperfusion injury in patients with acute myocardial infarction

目的:对急性心肌梗塞(AMI)再灌注后出现的特殊临床表现进行分析。方法:对50例AMI患者静脉溶栓后冠状动脉造影(显示为TIMI血流3级)的资料进行分析。结果:再灌注后有48例胸痛迅速缓解,有2例患者在再灌注后胸痛突然加重;有44例患者出现心律失常;40例出现一过性低血压;8例出现一过性ST段抬高。结论:冠脉血管再通后绝大部分患者胸痛迅速缓解,但大多有心律失常发生,一过性低血压,少数患者可出现ST段一过性胸痛加重;故溶栓后应进行持续心电图和血压监测。

Objective： To analyses the clinical manifestation of reperfusion injury in patients with acute myocardial infarction （AMI）. Methods： The data of reperfusion injury induced from thrombolyses in 50 AMI patents were analyzed retrospectively. Results： After reperfusion the chest pain quickly disappeared in 48 patients, transient ST elevation occurred in 8 patients and chest pain of two patients suddenly aggravated. Conclusion ： After reperfusion the chest pain quickly disappaers,arrhythmia and transient hypotension occur in most AMI patients;transient ST elevation and chest pain aggravate in few AMI patients, so must monitor electrocardiography and blood pressure after thrombolyses.
