Burgstaller JM, Held U, Gravestock I, et al. - A retrospective study was conducted to evaluate the effect of the introduction of the hs-troponin assay on the discharge diagnoses and the number of diagnostic tests in patients presenting with chest pain in a real-life setting in an emergency department (ED). Researchers correlated the standard troponin period (12/2009 to 11/2010) to the hs-troponin period (12/2010 to 12/2011). They examined data from 1,274 individuals (standard 597 (46.9%), hs-troponin 677 (53.1%)). The results indicated that the proportion of individuals with NSTEMI raised (hs-troponin 14.9% compared to 9.7%); the proportion in unstable angina (1.5% to 4.0%) and other cardiac illnesses (8.1% to 11.7%) declined. The average number of diagnostic tests reduced in individuals with chest pain presenting to an ED showing improved confidence of clinicians in their diagnosis, although the introduction of the hs-troponin test appeared in a higher proportion of positive hs-troponin tests in individuals with non-cardiac chest pain.
