Copeptin Does Not Add Diagnostic Information to High-Sensitivity Troponin T in Low- to Intermediate-Risk Patients With Acute Chest Pain: Results From the Rule Out Myocardial Infarction by Computed Tomography (ROMICAT) Study

Study Questions:

Does the addition of copeptin, a peptide derived from the AVP precursor, have incremental value to a high-sensitivity cardiac troponin T (hs-cTnT) in patients presenting to the emergency department (ED) with acute chest pain and low to intermediate risk for acute coronary syndrome (ACS)?
