Presence of concomitant left bundle-branch block (LBBB) in patients presenting with possible acute MI presents a diagnostic dilemma. The LBBB pattern distorts ST-segment changes, delaying or preventing accurate diagnosis. This article reviews the Sgarbossa criteria and ST\/S ratio and presents a treatment algorithm that may help improve patient care and reduce morbidity and mortality.<\/jats:p>","DOI":"10.1097\/01.jaa.0000525904.44484.5c","type":"journal-article","created":{"date-parts":[[2017,10,5]],"date-time":"2017-10-05T22:24:41Z","timestamp":1507242281000},"page":"16-21","source":"Crossref","is-referenced-by-count":0,"title":["Managing chest pain in patients with concomitant left bundle-branch block"],"prefix":"10.1097","volume":"30","author":[{"given":"Andrew","family":"Wyant","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somu","family":"Chatterjee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamara","family":"Bennett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"issue":"12","key":"R1-20230817","doi-asserted-by":"crossref","first-page":"1150","DOI":"10.1161\/01.CIR.97.12.1150","article-title":"Use of reperfusion therapy for acute myocardial infarction in the United States: data from the National Registry of Myocardial Infarction 2","volume":"97","author":"Barron","year":"1998","journal-title":"Circulation"},{"issue":"4","key":"R2-20230817","doi-asserted-by":"crossref","first-page":"329","DOI":"10.1016\/j.annemergmed.2007.12.006","article-title":"Electro-cardiographic criteria for detecting acute myocardial infarction in patients with left bundle branch block: a meta-analysis","volume":"52","author":"Tabas","year":"2008","journal-title":"Ann Emerg Med"},{"issue":"9030","key":"R3-20230817","doi-asserted-by":"crossref","first-page":"771","DOI":"10.1016\/S0140-6736(96)02514-7","article-title":"Early thrombolytic treatment in acute myocardial infarction: reappraisal of the golden hour","volume":"348","author":"Boersma","year":"1996","journal-title":"Lancet"},{"issue":"2","key":"R4-20230817","doi-asserted-by":"crossref","first-page":"96","DOI":"10.1016\/j.jacc.2012.02.054","article-title":"Evolving considerations in the management of patients with left bundle branch block and suspected myocardial infarction","volume":"60","author":"Neeland","year":"2012","journal-title":"J Am Coll Cardiol"},{"issue":"8","key":"R5-20230817","doi-asserted-by":"crossref","first-page":"528","DOI":"10.1056\/NEJM199602223340809","article-title":"Acute myocardial infarction and left bundle-branch block\u2014can we lift the veil","volume":"334","author":"Wellens","year":"1996","journal-title":"N Engl J Med"},{"issue":"11","key":"R6-20230817","doi-asserted-by":"crossref","first-page":"1565","DOI":"10.1016\/j.amjcard.2011.01.039","article-title":"Long-term cardiovascular outcomes in patients with angina pectoris presenting with bundle branch block","volume":"107","author":"Bansilal","year":"2011","journal-title":"Am J Cardiol"},{"issue":"3","key":"R7-20230817","doi-asserted-by":"crossref","first-page":"E1","DOI":"10.1016\/j.jacc.2004.07.014","article-title":"ACC\/AHA guidelines for the management of patients with ST-elevation myocardial infarction.
