2. Figure 1
Two-hour absolute (A, D, G), relative (B, E, H), and the combination of both (C, F, I) changes in hs-cTnT: Roche Diagnostics Corporation (Indianapolis, Ind) (top); hs-cTnI: Beckman Coulter Inc (Brea, Calif) (middle); hs-cTnI: Siemens (Munich, Germany) (bottom). Patients with acute myocardial infarction are shown on the right in green, and patients with other causes of chest pain are shown on the left in blue. hs-cTnI = high-sensitivity cardiac troponin I; hs-cTnT = high-sensitivity cardiac troponin T.

AUC of the 2-hour absolute changes, relative changes alone, and the combination of both changes in all patients for hs-cTnT, Roche (A); hs-cTnI, Beckman Coulter (B); hs-cTnI, Siemens (C); and in subgroup of patients with an elevated baseline hs-cTn level (with the relative change >20% shown on the graph) (D, E, F).
