急诊PCI和延期PCI患者QT离散度对比分析
Chinese Heart Journal（2007）
Abstract
目的对比不同时期经皮冠状动脉介入治疗(PCI)对急性心肌梗死(AMI)患者QT离散度(QTd)的影响。方法入选78例患者根据PCI手术时间分为急诊PCI组和延期PCI组,计算各患者术前和术后心电图QTd及心率校正QT间期离散度(QTcd)。然后观察两组术前和术后QTd及QTcd的差异。结果两组PCI组术后QTd及QTcd均较术前缩短(P<0.05)。与延期PCI组术后QTd相比,急诊PCI组术后QTd及QTcd显著缩短(P<0.05)。结论急诊PCI和延期PCI均能缩短AMI患者的QTd,但与延期PCI相比,急诊PCI术后QTd缩短更显著,表明急诊PCI疗效更佳。
