(A) Box plot of high‐sensitivity troponin T (hs‐TnT) values at baseline in the no‐ and mild‐ischemia group (group B) and in the moderate‐ to severe‐ischemia group (group A). (B) Box plot of hs‐TnT levels in individual subjects at baseline, 1 hour after the stress test, and 3 hours after the stress test. (C) Box plot of hs‐TnT levels in individual subjects who underwent the dobutamine stress test at baseline, 1 hour after the stress test, and 3 hours after the stress test. (D) Receiver operating characteristic (ROC) curve of baseline hs‐TnT levels ≥14 pg/mL and hs‐TnT ≥12 pg/mL, 3 hours after the stress test in predicting moderate to severe ischemia by magnetic resonance imaging. Abbreviations: ROC, receiver operating characteristic.
