From: Identification of acute myocardial infarction in patients with atrial fibrillation and chest pain with a contemporary sensitive troponin I assay

Fig. 1

Sensitivity and specificity of troponin I determined in the derivation cohort of 90 patients with suspected acute coronary syndrome and chronic atrial fibrillation to identify patients with acute spontaneous type 1 MI. The X-axis is presented on a logarithmic scale. Lines represent different troponin I thresholds associated with 90% sensitivity (A; 0.019 ng/ml); 90% specificity (C; 0.09 ng/mL) or with the highest sum of sensitivity and specificity (B; 0.04 ng/ml) for identification of patients with acute spontaneous type 1 MI
