摘要
目的:探讨QT间期(QTc)与急性ST抬高型心肌梗死患者梗死部位、心律失常类型及预后的关系。方法:选择430例急性ST抬高型心肌梗死患者作为研究对象,分析患者QTc、QRS宽度及左室射血分数(LVEF)与病情的关系。结果:随访1年,发生心血管不良事件患者与未发生心血管不良事件者比较,QTc、QRS宽度均显著延长,LVEF显著下降(P<0.05)。QTc延长组患者高侧壁、前壁心肌梗死发生率高于QTc正常组(P<0.05);QTc缩短组患者缓慢心律失常发生率显著高于QTc正常组(P<0.05)。QTc异常、QRS宽度延长及LVEF均为患者发生心血管不良事件的风险因素。结论:QTc与急性ST抬高型心肌梗死患者梗死部位及心律失常类型相关,QTc异常为患者预后不良的风险因素。
Objective：To explore the relationship of QTc with location of infarction,types of arrhythmia and prognosis of the patients with acute ST elevation myocardial infarction.Method：430 patients with acute ST-elevation myocardial infarction were selected as the research objects,the relationships of QTc,QRS duration and LVEF with disease condition were analyzed.Result：Follow up for 1 year,compared with the no adverse cardiovascular events,the QTc and QRS duration were greatly prolonged and LVED decreased of the patients with adverse cardiovascular events（P0.05）.The incidence of high side wall and anterior wall myocardial infarction of the QTc extension group was higher than that in the QTc normal group（P0.05）.Slow arrhythmia incidence rate of the QTc shortened group was higher than that in the QTc normal group（P0.05）.QTc abnormalities, QRS width extension and LVEF were all risk factors for adverse cardiovascular events.Conclusion：QTc is closely related with infarct location and the arrhythmia type,abnormal QTc is the risk factor for bad prognosis.
