    [Abstract] ObjectiveThe purpose of this study was to estimate the utility of ki netics of oxygen uptake (VO2), anaerobic threshold (AT) and cardiopulmonary fu nctional capacity during the exercise test in the assessment of patients with su spectable angina.MethodsTreadmill graded exercise tests with gas analysis 、coro nary angiography were conducted on sixty_eight patients with angina. According t o the result of coronary angiography, 68 patients were divided into coronary hea rt disease group (39 cases) and non_coronary heart disease group (29 cases). Th e difference of cardiopulmonary functions between two groups was evaluated.Results Compared with non_coronary heart disease group, coronary heart disease grou p showed statistical significance in VO2 peak[(20.67±6.01)vs(26.63±4.51)ml/ kg/min,P<0.001]、VCO2[(1.34±0.52)vs(1.72±0.49)l/min,P<0.01]、AT[ (1.21±0.36)vs(1.48±0.32)l/min,P<0.01]、O2 pulse peak[(10.39±3.04) vs(12.33±2.53)ml/beat,P<0.01]、VT[(1.37±0.43) vs (1.56±0.32)L,P <0.05]and VE/VCO2@AT[(31.18±4.79)vs(28.88±4.04),P<0.05]. Conclusions VO2 peak、AT and O2 pulse peak have potential va lue in diagnosing of coronary heart disease. ......
