Abstract Objective To estimate the diagnostic value of exercise treadmill test(TET) for coronary heart disease.Methods Carry out coronary angiography(CAG) on 150 patients with positive TET results. According to CAG results, divide them into true-positive group and false positive group, and then compare the differences of age and sex between the two groups. Statistically analyse the correlation between the amount of diseased vessels and sex in true-positive group; Compare the difference of leads whose ST-segments shifted between the two groups and analyse the relationship between the TET parameters and CAG. Results ① True-positive rate of TET is 60%, with 64.29% in males and 47.37% in females. ② In true-positive group, the proportion of males who are single-vessel, double-vessel and multi-vessel diseased is significantly higher than that of females and the difference is statistically significant(P<0. 05). ③ False-positive rate is high when ST-segments change in inferior leads (P<0. 05). ④ There lie significant differences between the two groups in aspects of total movement time complicated with the amplitude, time of occurrence and lasting time of downward shifting of ST-segments(P<0. 05).Conclusion TET is an ideal non-invasive testing method to diagnose coronary heart disease. Diagnostic accuracy can be improved if various exercise parameters are combined while comprehensive analysis is carried out.
