Peak troponin T in STEMI: a predictor of all-cause mortality and left ventricular function.

Background: The clinical significance of peak troponin levels following ST-elevation myocardial infarction (STEMI) has not been definitively established. The purpose of this study was to examine the relationship between peak high-sensitivity cardiac troponin T (hs-cTnT) and all-cause mortality at 30 days and 1 year, and left ventricular ejection fraction (LVEF) in STEMI.

Methods: A single-centre retrospective observational study was conducted of all patients with STEMI between January 2015 and December 2017.
