Whilst there has been near-universal uptake of this technology, there is considerable variability in how to assess acute chest pain patients using high-sensitivity cardiac troponins. This review describes the historical narrative for cardiac troponins and details the evidence base behind decision rules, such as single sample rule-out, single sample rule-in, and accelerated diagnostic protocols (ADPs). There is particular focus on the European Society of Cardiology (ESC) 0\/1 and 0\/3 h and the high-STEACS ADPs. The ESC 0\/3 h ADP appears to have reduced rule-out safety compared to both the ESC 0\/1 h and high-STEACS ADP. However, whilst high-STEACS performed well in its validation population, external validation in the US has been less impressive and warrants further investigation. The ESC 0\/1 h pathway has demonstrated strong rule-out performance, helped by its observational zone. However, real world implementation studies comparing these ADPs are required to understand their impact on Emergency Department efficiency and the safety of clinician decision-making.<\/jats:p>","DOI":"10.3390\/jcm15135125","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T10:41:01Z","timestamp":1782902461000},"page":"5125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Evolution of Accelerated Diagnostic Protocols for Suspected Myocardial Infarction"],"prefix":"10.3390","volume":"15","author":[{"given":"James","family":"Hatherley","sequence":"first","affiliation":[{"name":"Department of Cardiology, Liverpool University Hospital NHS Foundation Trust, Liverpool L7 8YE, UK"},{"name":"Institute of Life Courses and Medical Sciences, University of Liverpool, Liverpool L69 3GL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7000-5996","authenticated-orcid":false,"given":"Paul","family":"Collinson","sequence":"additional","affiliation":[{"name":"City St Georges, University of London, London EC1V 0HB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tarek","family":"Abuzahra","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Liverpool University Hospital NHS Foundation Trust, Liverpool L7 8YE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleem","family":"Khand","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Liverpool University Hospital NHS Foundation Trust, Liverpool L7 8YE, UK"},{"name":"Institute of Life Courses and Medical Sciences, University of Liverpool, Liverpool L69 3GL, UK"},{"name":"Department of Cardiology, Liverpool Heart and Chest Hospital, Liverpool L14 3PE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"147","DOI":"10.1007\/s11739-017-1612-1","article-title":"Cardiac biomarkers of acute coronary syndrome: From history to high-sensitivity cardiac troponin","volume":"12","author":"Garg","year":"2017","journal-title":"Intern.
