摘要
目的分析比较平板运动试验与冠状动脉造影对冠心病患者的诊断价值。方法选取我院心内科收治的115例疑似冠心病患者作为研究对象,并对其进行平板运动试验和冠状动脉造影检查,同时针对患者的检测结果进行全面的分析比较。结果通过冠状动脉造影、超声、心肌酶学检查三种方法结合,对115例疑似冠心病患者进行诊断,并视为病理证实结果,确诊为阳性患者75例,阴性患者40例。平板运动试验检测结果显示真阳性患者50例,真阴性患者30例,准确率为69.57%。平板运动试验检测与冠状动脉造影检测结果相比,差异无统计学意义(P>0.05)。冠状动脉的狭窄程度与平板运动试验中ST段改变运动的出现时间和持续时间有关,且经对比后,轻、中、重度冠状动脉病变患者的ST段压低出现时间、持续时间差异均有统计学意义(P<0.05)。结论平板运动试验可为冠心病的临床诊断提供应用价值较高的参考依据,值得推广应用。
Objective To analyze and compare the diagnostic value between the results of treadmill exercise test（ TET） and coronary angiography（ CAG） in patients with coronary heart disease（ CHD）. Methods One hundred and fifteen suspected CHD patients who had been admitted to the Department of Cardiology in our hospital were selected as research subjects. They underwent TET and CAG examination,and the testing results were made rounded analysis and comparison. Results The three methods of CAG,ultrasound and myocardial enzyme examination were applied to diagnose the 115 suspected CHD patients. The outcomes were considered as pathological findings,that was,75 and 40 patients were diagnosed as positive and negative,respectively. By TET results,50 patients were true positive while 30 were true negative,and the accuracy rate was 69. 57%. The difference between TET and CAG testing results was not statistically significantly（ P〉0. 05）. The degree of coronary stenosis was related to the occurrence time and duration of ST-segment changes in TET. The occurrence time and duration of ST-segment depression among patients with mild,moderate and severe coronary artery lesions varied significantly（ P〈0. 05）. Conclusion TET results provides highly valuable reference for CHD diagnosis and thus TET is worthy of being promoted and applied clinically.
