RT Journal Article SR Electronic A1 Vinall, Maria T1 Copeptin May Be Useful in Quickly Ruling Out NSTEMI in Some Patients JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 42 SP 13 OP 13 DO 10.1177/155989771442007 UL http://mdc.sagepub.com/content/14/42/13.1.abstract AB While cardiac troponin is essential in the diagnosis of acute myocardial infarction, it is possible that other biomarkers may improve diagnosis in patients who present early or may have other causes of troponin elevation. This article presents results of the COPeptin in ED [COPED] study indicating that copeptin may be a useful biomarker to rule out NSTEMI among patients who present to the emergency department with acute chest pain but have a pacemaker and a normal troponin value at baseline.
