Outcomes in patients with chest pain in emergency departments using high-sensitivity versus conventional troponins.

There is a paucity of data regarding the association between the use of high-sensitivity troponin (hs-cTn) compared with conventional troponin (cTn) and outcomes in chest pain patients in emergency departments (EDs). This study examined the impact of hs-cTnT on prognosis in chest pain patients in EDs. In an observational cohort study, we included chest pain patients visiting the EDs of 14 hospitals in Sweden from 2011 to 2016.

High-Sensitivity Troponins and Outcomes After Myocardial Infarction.

Background: It remains unknown how the introduction of high-sensitivity cardiac troponin T (hs-cTnT) has affected the incidence, prognosis, and use of coronary angiographies and revascularizations in patients with myocardial infarction (MI).

Objectives: The aim of this study was to investigate how the incidence of MI and prognosis after a first MI was affected by the introduction of hs-cTnT.

Methods: In a cohort study, the authors included all patients with a first MI from the Swedish National Patient Registry from 2009 to 2013.
