Abstract：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 STsegment changes in TET. The occurrence time and duration of STsegment 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.
