BACKGROUND: @entity25736 ( @entity25736 ) and an exercise treadmill test (ETT) are recommended for the initial evaluation of possible @entity453 ( @entity453 ), but the applicability of these tests in Korean @entity1 has not been evaluated. METHODS: Korean @entity1 with @entity25736 , ETT, and invasive coronary angiography results were enrolled. Across all @entity25736 levels, @entity25736 and ETT statistics were evaluated and independent @entity453 predictors obtained. RESULTS: Of the 335 @entity1 (mean age 58.0        10.2 years), 99 and 236 were in the low (LPTP) and intermediate @entity25736 (IPTP) groups, respectively. The observed prevalence of @entity453 was significantly lower than the @entity25736 . (7.1% vs. 9.1        4.9% in LPTP, p   <   0.001; 23.3% vs. 33.0        15.1% in IPTP, p   <   0.001) The ETT's sensitivity and positive predictive values (PPVs) appeared lower than previously reported (LPTP: 42.9% and 16.7%; IPTP: 61.8% and 37.0%), whereas the negative predictive values (NPVs) were higher (LPTP: 95.1%; IPTP: 85.4%). After multivariate adjustments, positive ETT (odds ratio 3.276, 95% confidence interval 1.643-6.532, p   =   0.001) independently predicted the presence of @entity453 , but the @entity25736 showed only marginal predictability (odds ratio 1.019, 95% confidence interval 0.998-1.041, p   =   0.069). CONCLUSIONS: In Korean @entity1 , the observed prevalence of @entity453 was lower than the @entity25736 , and @entity25736 showed only marginal @entity453 predictability. Although a positive ETT independently predicted @entity453 , the ETT showed lower sensitivity and PPVs than previously reported. Despite the limited value of @entity25736 and ETT, the high NPVs of ETT appear useful for saving @entity1 from unnecessary further examinations.
