Usefulness of copeptin in discarding non-ST elevation acute myocardial infarction in patients with acute chest pain and negative first troponin I.
To evaluate the usefulness of copeptin as a rapid and reliable marker for discarding non-ST elevation acute myocardial infarction (NSTEMI) in patients attended in an Emergency Care Department due to acute chest pain with a normal or non-diagnostic electrocardiogram and a negative first troponin I result. ⋯ Copeptin determination upon admission to the Emergency Care Department in patients with chest pain for ≤12h, suggestive of acute coronary syndrome, with a non-diagnostic electrocardiogram and a negative first troponin I determination does not allow rapid and reliable exclusion of the presence of NSTEMI. Serial troponin I measurements are needed in this respect.
