银杏叶提取物对急性心肌梗死患者的QT离散度的影响

目的探讨银杏叶提取物(EGb)对急性心肌梗死(AMI)患者QT离散度(QTd)的影响。方法40例AMI患者随机分为对照组(20例)和治疗组(20例)。两组均予以常规治疗,治疗组在常规治疗基础上加用EGb20mL/d静脉滴注治疗,疗程为2周。治疗前后测定和比较QTd及校正QT离散度(QTcd)。结果治疗后两组QTd及QTcd较治疗前缩短(P<0.05),但治疗组比对照组更加明显(P<0.01)。结论EGb能明显缩短AMI患者的QTd,改善预后。

Impact of Ginkgo Biloba Extract on QT Dispersion in Patients with Acute Myocardial Infarction

Objective To investigate impact of Ginkgo biloba extract （EGb） on QT dispersion （QTd） in patients with acute myocardial infarction （AMI） patients. Methods 40 cases of AMI patients were randomly divided into the control group （20 cases） and the treatment group （20 cases）. Both groups were treated with conventional therapy, the treatment group was added with EGb20mL/d intravenous drip treatment on the basis of conventional treatment .They were treated for two weeks. QTd and calibration QT dispersion （QTcd） were assayed and compared before and after treatment. Results QTd and QTcd after treatment were reduced than those before treatment （P〈0.05）, but those become more obviously in the treatment group compared with the control group （P〈0.01）. Conclusion EGb can significantly reduced QTd in patients with AMI and improve the prognosis.
