三种负荷试验对冠心病诊断的对比研究

Three kinds of stress methods in the diagnosis of coronary artery disease

摘要

摘要: 目的: 以冠状动脉造影结果为标准, 评价ATP负荷超声心动图试验 (ATPE)、多巴酚丁胺负荷超声心动图试验 (DOBE)和平板运动心电图试验 (EE)对冠心病的诊断价值。方法: 对 5 6例疑诊冠心病患者而行冠状动脉造影检查的患者, 在同期内, 即间隔 <4周, 分别接受ATPE、DOBE和EE负荷试验, 将冠状动脉造影结果分别与三项负荷试验结果对比分析。结果: ATPE、DOBE和EE负荷试验诊断冠心病的敏感性分别为: 80%、83%和 77%;特异性分别为: 96%、88%和 81%。检出冠心病的准确率分别为 88%、86%、79%。结论: ATPE、DOBE和EE三种负荷试验对冠心病的诊断有着较高的敏感性和特异性, 费用低, 重复性好, 是比较安全、有效的检查方法, 而选用何种检查要依据患者具体情况来确定。

Abstract: Objective:To evaluate the diagnostic value of three kinds of methods: exercise electrocardiography（EE）,dobutamine stress echocardiography（DOBE） and ATP stress echocardiography （ATPE） in coronary artery disease（CAD） according to coronary angiography. Methods: There are fifty-six patients who were examined with coronary angiography, EE, DOBE and ATPE. The date of coronary angiography were compared with the three kinds of methods. Results: The sensitivity in the diagnosis of CAD with the three kinds of methods were 77%,83% and 80%,respectively.The specificity were 81%,88% and 96%, respectively. The accuracy were 79%,86%,88%, respectively. Conclusions: The three kinds of methods had high sensitivity and specificity, and reached high diagnostic accuracy. They were lower cost and effective metheds.
