目的 :探讨平板运动试验 (TET)对冠心病的诊断价值及对冠脉病变严重程度的评价。方法 :对经临床确诊的 2 0例冠心病心绞痛病人及 10例“正常人”,用 TET、核素心肌显像 (SPECT)与冠状动脉造影结果作对比分析。结果 :TET诊断冠心病的敏感性为 80 % ,特异性为 70 % ,准确性为 6 6 .6 % ;而 SPECT的相应值为 85 .7%、 80 %、83.3% (P<0 .0 5 ) ;运动时间的长短与冠脉病变严重程度密切相关。结论 :TET是一种安全、简易和实用的无创性冠心病诊断试验 ,值得推广应用
Objective: To investigate the diagnostic value of treadmill exercise test (TET) in coronary heart disease and evaluate the severity of coronary artery disease. Methods: 20 clinically diagnosed patients with coronary heart disease angina pectoris and 10 normal subjects were analyzed by TET, SPECT and coronary angiography. Results: The sensitivity, specificity and accuracy of TET in diagnosis of coronary heart disease were 80%, 70% and 66.6%, respectively. The corresponding values of SPECT were 85.7%, 80% and 83.3% (P <0. 5). The duration of exercise is closely related to the severity of coronary artery disease. Conclusion: TET is a safe, simple and practical non-invasive diagnosis of coronary heart disease, it is worth promoting
