Chest pain is one of the most common reasons for an emergency room (ER) visit in the world, with more than 10 million ER visits annually. High-sensitivity cardiac troponin (hscTn) assays have the ability to rapidly rule in or rule out acute coronary syndrome with improved sensitivity, and they are increasingly being used. Though hscTn assays have been approved for use in European, Australian, and Canadian guidelines since 2010, authorities only approved their use in 2017. There is no consensus on how to compare the results from various hscTn assays. A literature review was performed to analyse the advantages and limitations of using hscTn as a standard biomarker to evaluate patients with suspected Acute Coronary Syndrome (ACS) in the emergency setting.
