High sensitivity cardiac troponin assays utilise improved precision at very low concentrations to improve the diagnosis and risk stratification of patients with suspected acute coronary syndrome.The High-Sensitivity Troponin in the Evaluation of patients with suspected Acute Coronary Syndrome (High-STEACS) trial was a randomised controlled trial to evaluate the impact of implementing these recommendations from the Universal Definition of Myocardial Infarction.In this secondary observational analysis of the High-STEACS trial, we aimed to determine whether implementation of a high sensitivity cardiac troponin I assay could reduce myocardial infarction or death at five years in patients presenting with suspected acute coronary syndrome.
