Popis: | The diagnosis of non ST elevation myocardial infarction (NSTEMI) is very important for the emergency doctor. According to the literature copeptin, a marker of the endogenous stress, combined with troponin could be of interest in this diagnosis. The objective of the study was to investigate the association of high-sensitivity (HS) troponin and copeptine to eliminate the diagnosis of NSTEMI or unstable angina (UA) in patients arriving in Casualty with a thoracic pain. This prospective study included patients showing up at Casualty with a thoracic pain less than 12 hours old. Copeptin was measured by the BRAHMS method at admission and HS troponin was measured at admission, after 2 and 6 hours. The patients also had a follow-up phone call after 3 months. The study included 114 patients with an average age of 54.6 years. NSTEMI was diagnosed for 8.8% of them and UA for 6.1%. The patients presenting NSTEMI or UA had a copeptin rate at admission higher than the others (24.7 pmol/L versus 7.1; p0.002). The negative predictive value of the association of HS troponin and copeptin was 95% whereas the sensitivity was 76.5% and the specificity 78.4%. The ROC curve analysis of the copeptin results brought to light a positivity limit which would have been more successful at 10.3 pmol/L than at 14.0. The association of copeptin and HS troponin can be useful to exclude the diagnosis of NSTEMI and favours faster treatment in Casualty. |
