摘要
目的探讨冠心病患者经皮冠状动脉介入治疗前后其心电图缺血性J波变化，为临床无创检查提供可靠依据。方法随机选取本院2013年1月至2015年7月期间收治的冠心病行经皮冠状动脉介入治疗的患者8l例，包括54例不稳定性心绞痛（心绞痛组）和27例急性心肌梗死（心梗组），对患者PCI手术前后24h内12导联心电图检查结果进行分析，测量记录各导联J波时限和振幅，并分析患者手术前后J波参数。结果81例冠心病患者在PCI手术前后其五个导联组的J波发生导联数相比差异无统计学意义（P〉0．05）；PCI术后患者巨大J波和大J波比例明显下降，小J波比例明显上升，差异具有统计学意义（P〈0．05）。结论J波可作为冠心病患者近期预后的可靠评估指标，但是对于PCI手术前后冠心病患者缺血性J波时限、波幅的变化有待于在今后进一步深入研究。
Objective To provide some references for the noninvasive clinical examination exploring the changes of electrocardiograhpic ischemic J waves before and after percutaneous coronary intervention （PCI） for patients with coronary artery disease. Methods 81 patients with coronary artery disease admitted into our hospital from January, 2013 to July, 2015 and taking percutaneous coronary intervention were randomly selected; among which, 27 got acute myocardial infarction and 54 unstable angina. The results of 12-lead electrocardiogram before and within 24 hours after PCI in the patients were analyzed. The amplitude and time of J waves were measured and recorded. The J wave parameters before and after the treatment were analyzed. Results There were no statistical differences in the incidence of J waves of between the 5 lead-groups before and after operation （P〉0.05）; the scale of giant J wave and big J wave decreased significantly and the scale of small J wave increased significantly, with statistical differences （P〈0.05）. Conclusions J wave could be a reliable evaluation indicator for evaluating the short-term prognosis of patients with coronary artery disease; while the changes of the amplitude and time of the ischemic J wave before and after PCI for patients with coronary artery disease need further study in the future.
