摘要:
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。
Abstract:
AIM To examine the effect of percutanious coronary intervention (PCI) conducted at different time on QT dispersion (QTd) in patients with acute myocardial infarction (AMI). METHODS Seventyeight patients was divided into two groups according to the time of PCI: acute PCI and delayed PCI. We calculated QTd of standard 12 leads electrocardiograms before PCI and after PCI in all the patients and then observed the difference of QTd between the two groups. RESULTS In both groups, the QTd after PCI was remarkably shorter than the QTd before PCI (P<0.05). The QTd of the acute PCI group was much shorter than that of the delayed PCI group (P<0. 05). CONCLUSION Successful PCI notably reduces the QTd in patients with AMI. But comparing with that of delayed PCI, the QTd of acute PCI is much shorter, indicating that acute PCI has better efficacy than delayed PCI in patients with AMI.
