Etaher A, Nguyen TL, Saad YM, et al. - Researchers here examined if and how baseline level(s) of high sensitivity troponin T (HsTnT), adjudicated diagnoses and outcomes are associated in patients aged ≥ 80 years who presented to the emergency departments with symptoms suggestive of an acute coronary syndrome (ACS). At Liverpool Hospital, NSW, Australia, 2,773 patients were screened during the 4 months study period from March to June 2014. Of these, 545 were aged ≥ 80 years; median follow-up period was 32 months. Increased mortality was observed among patients aged ≥ 80 years in correlation with higher HsTnT levels; this correlation was observed irrespective of adjudicated diagnoses. In most very elderly patients presenting with symptoms suggestive of an ACS, elevated levels of HsTnT were observed most commonly due to chronic myocardial injury.
