Fig. 2From: Identification of acute myocardial infarction in patients with atrial fibrillation and chest pain with a contemporary sensitive troponin I assayAbsolute (a) and relative (b) changes in troponin I concentration within 3 hours after admission in the validation cohort in patients with atrial fibrillation with or without acute spontaneous type 1 MI. The X-axis is presented on a logarithmic scale. Dotted vertical lines represent absolute or relative troponin I changes associated with 90 % specificity for identification of an acute spontaneous MI. The X-axis is truncatedBack to article page
