目的探讨12导联动态心电图联合平板运动试验对冠状动脉粥样硬化性心脏病患者诊断敏感性及特异性的影响。方法选取2014年5月至2016年2月辽宁省大连市普兰店区中心医院108例疑似冠状动脉粥样硬化性心脏病患者,均行12导联动态心电图和平板运动试验检测,以冠壮动脉造影为金标准,统计对比12导联动态心电图、平板运动试验单一检测与联合检测的敏感性及特异性。结果联合诊断敏感性为83.08%(54/65)、特异性为79.07%(34/43)及准确性为81.48%(88/108)均高于单一诊断,差异有统计学意义(P<0.05)。结论 12导联动态心电图联合平板运动试验可提高诊断冠状动脉粥样硬化性心脏病敏感性、特异性,临床具有较高的诊断价值,。
Objective To investigate the diagnostic sensitivity and specificity of 12-lead Holter combined with treadmill exercise test in patients with coronary atherosclerotic heart disease. Methods From May 2014 to February 2016, 108 patients with suspected coronary atherosclerotic heart disease in Pulandian Central Hospital of Dalian City, Liaoning Province were selected. All patients underwent 12-lead Holter monitoring and treadmill exercise test. Angiography as the gold standard, statistical contrast 12-lead Holter, treadmill exercise test single detection and joint detection of sensitivity and specificity. Results The diagnostic sensitivity was 83.08% (54/65), the specificity was 79.07% (34/43) and the accuracy was 81.48% (88/108), which was higher than that of single diagnosis (P <0.05 ). Conclusions 12-lead Holter combined with treadmill exercise test can improve the sensitivity and specificity of diagnosis of coronary atherosclerotic heart disease, and has high diagnostic value in clinic.
