目的:总结踏板运动试验(treadmill exercise test,TET)在诊断冠状动脉粥样硬化性心脏病(冠心病)中的应用体会。方法:对238例疑诊冠心病患者进行TET及冠状动脉造影(coronary ar-terigraphy,CAG),以CAG的诊断结果为金标准,分析TET的总敏感度、特异度,比较不同性别组的敏感度、特异度。结果:TET的总的敏感度为79%,特异度为82%。男性组的敏感度为78%、特异度为90%,女性组的敏感度为80%、特异度为68%,男性组与女性组的敏感度比较,P(0.05,特异度比较,P(0.05。结论:①TET对诊断冠心病有较高的特异度,有较高的临床使用价值;②TET对诊断男性冠心病的特异度较女性高;③TET无创,且价格便宜,患者容易接受,适合基层单位用于冠心病的辅助诊断。 Objective: To summarize the application experience of treadmill exercise test (TET) in the diagnosis of coronary atherosclerotic heart disease (CHD). Methods: TET and coronary ar-terigraphy (CAG) were performed in 238 suspected coronary heart disease patients. The diagnostic value of CAG was taken as the gold standard. The total sensitivity and specificity of TET were analyzed. The sensitivity of different gender groups was compared Degree, specificity. Results: The overall TET sensitivity was 79% and the specificity was 82%. The sensitivities of men and women were 78% and 90% respectively. The sensitivities of women were 80% and 68%, respectively. The sensitivity of men and women was significantly higher than that of women (P <0.05, P 0.05.Conclusion: ①TET has higher specificity for diagnosis of coronary heart disease, and has higher clinical value; ②TET is more specific than men for the diagnosis of coronary heart disease in men; ③TET is noninvasive, and the price is cheap, the patient is easy to accept, suitable for the grassroots Unit for the diagnosis of coronary heart disease.
