1、心电图ST-T段改变对冠心病诊断的临床价值研宄DOI:10.7504/nk2016010203中图分类号:R587.1文献标识码:A摘要:目的分析心电图ST-T段改变在冠心病诊断中的临床价值。方法便利选取2014年5月至2016年3月住我院治疗的180例疑似冠心病患者为研究对象,对180例患者均实施18导联常规心电图检查及冠状动脉造影检查,比较两种检查的检测结果;同时采集患者的临床资料,进一步分析年龄、性别、体重指数、吸烟史、糖尿病史、高血压病史等因素对冠心病病变严重程度的影响。结果心电图检查诊断冠心病的敏感度为51.85%,特异度为88.89%,确诊率为66.6
2、7%;108例冠心病患者经冠状动脉造影检查发现,有50例患者存在单支病变,有14例(28.00%)患者出现心电图ST-T段改变,有58例患者存在多支病变,有32例(55.17%)患者出现心电图ST-T段改变,单支病变的阳性率显著低于多支病变的阳性率,P<0.05;在心电图ST-T段改变情况下,冠心病组和非冠心病组患者之间的性别、高血压、血糖存在显著差异,P<0.05。结论心电图ST-T段改变在冠心病诊断中只有一定的临床价值,确诊率较高,且对冠心病严重程度的诊断(尤其是多支病变的诊断)只有显著的临床意义。关键词:心电图;ST-T段改变;冠心病Clinicalvalu
