Elsisy MF, et al. - Researchers sought to report on emergency coronary artery bypass surgery (CABG) via studying 14,455 isolated CABG performed at Mayo Clinic from 1993 to 2019. They described baseline characteristics and in-hospital outcomes of emergent CABG in consecutive eras (1993 to 2000, 2001 to 2010, and 2011 to 2019). Of 14,455 isolated CABG, 427 (2.95%) were emergent. A decrease in the number of emergent CABG, especially those performed due to complications of coronary interventions, was observed in the consecutive study eras. A temporal rise in the prevalence of heart failure was observed, but with no change in mean age, and prevalence of hypertension, diabetes, renal failure, or atrial fibrillation. Although there was higher prevalence of left ventricular dysfunction and more complete revascularization in more recent years, no increase in in-hospital mortality observed.
