摘要/Abstract

摘要： 本文对实时超声心动图（RTE）与平板运动心电图（TET）诊断冠心病（CHD）的价值进行了研究与分析。选取2016年6月～2018年6月疑似CHD患者100例，所有患者均给予RTE、TET检查，并以冠脉造影（CAG）作为金标准，采用受试者工作特征（ROC）曲线分析RTE与TET对CHD的诊断价值。CAG结果显示，100例疑似CHD患者中，CHD患者40例（40.00%）、非CHD患者60例（60.00%）；ROC曲线分析结果显示，在诊断CHD敏感度、特异度、准确度、曲线下面积中，RTE为85.00%、86.67%、86.00%、0.837，TET为80.00%、76.67%、78.00%、0.768，RTE与TET联合为100.00%、96.67%、98.00%、0.924，明显高于RTE、TET，差异有统计学意义（P<0.05），RTE高于TET，但差异无统计学意义（P>0.05）。本文证实了RTE、TET是诊断CHD重要的方法，且RTE与TET联合的诊断敏感度、特异度、准确度、曲线下面积更高。

Abstract: The value of real-time echocardiography (RTE) and treadmill exercise electrocardiogram (TET) in the diagnosis of coronary heart disease (CHD) was analyzed in this study. 100 patients with suspected CHD were selected as the subjects of study from June 2016 to June 2018 in our hospital, all the patients were examined by RTE and TET. Coronary angiography (CAG) was used as the gold standard. The diagnostic value of RTE and TET for CHD was analyzed by receiver operating characteristic (ROC) curve. The results of CAG showed that, among 100 suspected CHD patients, 40 (40.00%) had CHD, and 60 (60.00%) had non-CHD. The results of ROC curve analysis showed that, in the sensitivity, specificity, accuracy and area under the curve of CHD diagnosis, the RTE were 85.00%, 86.67%, 86.00%, 0.837, the TET were 80.00%, 76.67%, 78.00%, 0.768, the RTE combined with TET were 100.00%, 96.67%, 98.00%, 0.924, RTE combined with TET was significantly higher than RTE and TET (P< 0.05), RTE was higher than TET, but there was no statistical difference(P>0.05). This study confirms that, RTE and TET are important methods for diagnosis of CHD, and the combination of RTE and TET has the higher sensitivity, specificity, accuracy.
