| Summary: | Evidence-informed recommendations on the use of cardiac troponin for the rapid diagnosis of acute coronary syndrome (ACS) in the emergency department (ED) were developed by the CADTH Health Technology Expert Review Panel (HTERP) to address the following policy questions: 1. Question 1: In light of the discontinuation of the conventional cardiac troponin T assay and the development of high-sensitivity cardiac troponin assays to determine cardiac ischemia in patients presenting in the ED with chest pain, which of the other troponin assays should hospitals adopt? Does one of the troponin assays offer an advantage as compared with the others when used in the ED setting? 2. Question 2: Are there evidence-based strategies available to optimize the use of troponin tests in the ED setting? For a particular troponin test, does one of these strategies result in better outcomes?
