摘要:
目的:探讨冠状动脉腔内成形术加支架安置(PTCA+stent)对急性心肌梗死(AMI)患者QT离散度(QTd )的影响，以及梗死部位对QTd变化的影响。方法:AMI患者70例，按体表心电图定位分类，均成功施行PTCA+stent，分别记录术前、术后1,5,7 d的12导联心电图，计算QTd及QTcd o结果:各组患者QTd比对照组显著增加(P<0.01 )，不同梗死部位时QTd,QTcd变化的影响无显著差异(P>0.05)，各组QTd,QTcd术前与术后1d比较有显著差异(P<0.01)，术后5d,7d与术后1d比较有显著差异(P<0.01).结论:AMI患者QTd增大，PTCA+stent可以明显缩短AMI患者QTd.
Abstract:
AIM:To investigate the effct of coronary angioplasty and stent implantation on QT dispersion(QTd) of patients with acute myocardial infarction(AMI).METHODS: This retrospective study was performed on 70 patients with AMI who successfully underwent pecutaneous transluminal coronary angioplasty(PTCA) and stent implantation. We examined the QTd and corrected QTd(QTcd) of standard 12-lead electrocardiogram of patients before and 1，5，7 day after PTCA and stent. RESULTS: Before PTCA and stent,the QTd and QTc do fall patients significantly increased compared with control group(P<0.0 1),and 1 dafter operation,reduced remarkably(P<0.01). The changes of QTd and QTcd were similar in different location of myocardial infarction (P>0.05). CONCLUSON: The QTd increased in patients with AMI，and reduced significanfly after PTCA and stent.
