延期支架术对溶栓再通的急性心肌梗死QTc离散度的影响

Effect of delayed coronary stenting on QTc dispersion in AMI with successful thrombolytion

目的 观察延期经皮冠状动脉支架术对急性心肌梗死静脉溶栓再通患者QTc离散度(QTcd)的影响。方法 选择 72例接受静脉溶栓治疗再通的急性心肌梗死患者 ,分别测量溶栓前后和延期支架术后的QTcd。结果 溶栓和支架术后较溶栓前显著缩短 (5 0 4± 11 3,5 8 8± 15 3,85 4±19 7,P <0 0 5 ) ,支架术后较溶栓后有所缩短 ,但无显著差异 (P >0 0 5 )。结论 延期支架术和静脉溶栓均能使急性心肌梗死QTcd显著降低 ,延期支架术更明显 ,但无统计学差异 ,其远期效果有待进一步观察。

Object To evaluate the effects of delayed coronary stenting on QTc dispersion in AMI with successful thrombolytion.Methods 72 acute myocardial infarction with patients successful thrombolytion were studied,QTcd with entering the hospital,three days later of thrombolytion and delayed coronary stenting were measured,respectively.Result QTcd with entering the hospital,three days later of thrombolytion and delayed coronary stenting were 85.4±19.7,58.8±15.3,50.4±11.3,respectively( P <0 05).Conclusion Delayed coronary stenting could reduce more shortly QTcd in grade than successful thrombolytion,but no difference on statistics and long-term results need further study.
