Diagnosing or ruling out acute myocardial infarction (AMI) is a challenge faced daily in emergency departments. AMI evaluation usually requires the measurement of the cardiac troponin (cTn) concentration. The use of this biomarker improves AMI diagnosis provided the concentrations are properly interpreted in the context of the patient's condition and according to standard recommendations. ⋯ The authors recommend measuring the cTn concentration if AMI is suspected in emergency patients, whether the newest high-sensitivity cTn assays or the so-called contemporary ones are used. Diagnostic algorithms based on up-to-date evidence are also presented. The consensus statement aims to serve as a clinical practice guideline for using cTn assays to enhance the efficient differential diagnosis of acute coronary syndromes in the emergency department.
