AMI = acute myocardial infarction; AUC = area under the curve; cTnI = cardiac troponin I; cTnT = cardiac troponin T; ED = emergency department; hs-cTnI = high-sensitivity cardiac troponin I; hs-cTnT = high-sensitivity cardiac troponin T; NA = not available; ROC = receiver operating characteristic curve.
