Abstract：Objective To investigate the clinical value of treadmill exercise test(TET) in the diagnosis and prognosis risk evaluation of coronary heart disease. Methods A total of 206 patients with suspected coronary heart disease were selected who had been admitted in our hospital from March 2012 to March 2014. All the enrolled cases underwent examinations of coronary angiography(CAG) and TET within two weeks after admission. Taking CAG results as diagnostic criteria, we evaluated the accuracy of TET results. Result In the diagnosis of coronary heart disease by TET, the diagnostic accordance rate was 84.1%, the specificity was 73.2%, the sensitivity was 89.7%, and the diagnostic accuracy was 62.4%. The positive rate was 79.3%, 83.1% and 100% respectively for patients separately with lesions in single vessel, two and three vessels; pairwise comparison among the three groups indicated that the differences were statistically significant(P<0.05). Conclusion TET is a noninvasive inspection method with relatively high diagnostic accordance rate, specificity and sensitivity. It is worthy of being promoted and applied clinically.
