摘要
目的 观察急诊冠状动脉介入术（PCI）对急性心肌梗死（AMI）患者QT离散度（QTd）的影响。方法 31例发生于6h以内的AMI患者，均行急诊PCI治疗，观察治疗前后QTd的变化，并与同期正常者对照。结果 AMI组QTd较正常组显著延长（P〈0．01），PCI成功后2hQTd较术前明显缩短，伴随心律失常组，其QTd明显高于不伴心律失常正常组。而不同梗死部位间QTd差异无统计学意义。结论 QTd可预见AMI患者有无出现心律失常危险，急诊PCI可显著降低AMI患者的QTd。
Objective To evaluate the effect of early percutaneous coronary intervention （PCI） in acute myocardial infarction（AMI） on QT dispersion （QTd）. Methods Thirty -one AMI patients and 26 patients with chest distress, pain but coronary arteriongraphy is no abnormalities as control group;PCI was done imediately after patients to hospital and QTd was mehsured before and after PCI. Results QTd was significantly prolonged in patients in AMI before PCI compared with control group [ （84 ±13） ms vs（59 ± 11 ） ms, P 〈 0. 01 ） ]. Two hours after PCI QTd decreased significantly（60 ± 12） ms. QTd was significantly longer in these patients with malignant ventricular anrrhythmia compared with those patients without anrrhythmia[ （92 ± 12） ms vs（ 83 ±14） ms, P 〈 0.05 ） ]. There was no significant difference in QTd between anterior AMI and inferior AMI. Conclusion Early PCI was associated with the reduction of QTd and decreased risk of ventricular anrrhythmia in AMI patients.
