Left bundle-branch block in patients with acute myocardial infarction: Presentation, treatment, and trends in outcome from 1997 to 2016 in routine clinical practice

Acute myocardial infarction patients with new or presumed new LBBB presence are at high risk of morbidity and mortality. They were treated less aggressively, and although mortality has halved during the last 20 years, there may be room for further improvement. Additional studies are needed to better identify those patients with LBBB who may maximally benefit from an early invasive treatment strategy.
