目的探讨银杏达莫注射液对冠心病PCI术后患者QT离散度(QTd)的影响。方法选取我院2013年1月-2014年1月接受冠心病PCI手术的患者220例,随机分为观察组和对照组,各110例,观察组采用银杏达莫注射液进行干预,对照组采用常规治疗,测量两组患者术前及术后10d的QTd。结果术前和术后1d两组患者QTd无显著差异(P>0.05),无统计学意义;两组患者各自的术前和术后QTd存在显著差异(P<0.05),有统计学意义;术后10d观察组的QTd显著优于对照组的QTd,存在差异(P<0.05),有统计学意义。结论银杏达莫注射液对冠心病PCI术后患者的QTd显著降低,值得在临床上广泛使用。
Objective To investigate the effect of Yinxingdamo injection on QT dispersion (QTd) in patients with coronary artery disease after PCI. Methods A total of 220 patients undergoing PCI from January 2013 to January 2014 in our hospital were randomly divided into observation group and control group, with 110 cases in each group. The observation group was treated with Yinxingdamo injection and the control group Routine treatment measures the QTd of both groups before and 10 days after operation. Results There was no significant difference in QTd between preoperative group and postoperative 1d group (P> 0.05). There was a significant difference in QTd between the two groups before and after operation (P <0.05) The QTd of the observation group at 10 days after operation was significantly better than that of the control group (P <0.05), which was statistically significant. Conclusions Yinxingdamo injection significantly reduces QTd in patients with coronary artery disease after PCI, which is worth to be widely used clinically.
