BACKGROUND:We evaluated kinetic changes of highsensitivity cardiac troponin T (hs-cTnT) in patients with acute coronary syndrome (ACS) and patients with hs-cTnT increases not due to ACS to rule in or rule out non-ST-segment elevation myocardial infarction (STEMI).

BACKGROUND:Two recent clinical trials showed that adding copeptin to a conventional cardiac troponin assay improved diagnostic performance for patients with chest pain early after symptom onset. We prospectively tested whether copeptin adds information to that provided by a high-sensitivity cardiac troponin T (hscTnT) assay in the early evaluation of patients with suspected acute myocardial infarction, particularly non-ST-segment elevation myocardial infarction (non-STEMI).
