| 摘 要： | ①目的探讨经皮冠状动脉成形术及支架安置术(PCI)对急性心肌梗死(AMI)病人恢复期QT间期离散度(QTd)的影响。②方法测定152例AMI恢复期病人PCI术前、术后QTd及校正的QTd(QTcd),并与同期151例冠状动脉造影正常者进行对比。③结果AMI恢复期病人PCI后QTd及QTcd较术前明显减小(t=20.926、13.543,P<0.01);单纯行冠状动脉造影对QTd无明显影响;下(正后)壁与前(高侧)壁AMI术前及术后比较,QTd及QTcd无显著差异。④结论PCI可以显著缩短AMI病人QTd,有效地避免心律失常和心源性猝死的发生,从而改善病人的预后。

| Abstract: | Objective To observe the changes of QT interval dispersion (QTd) after successful percutaneous coronary intervention (PCI) in the recovery period after acute myocardial infarction (AMI). Methods QTd and corrected QTd (QTcd) mere measured in 152 AMI patients who underwent PCI before and after operation; and the findings were compared with 151 subjects with normal coronary arteriography. Results QTd and QTcd were significantly decreased after PCI or stenting (t=20.926,(13.543); P<0.01). There was no significant difference in QTd and QTcd between coronary angiography; and no significant difference in QTd and QTcd between anterior and interior AMI. Conclusion PCI can significantly reduce QTd and QTcd, and prevent serious ventricular arrhythmia, reduce sudden cardiac death, and improve the prognosis of AMI patients. |
