Incidence, Characteristics, and Outcomes of Emergent Isolated Coronary Artery Bypass Grafting
Section snippets
Methods
We retrospectively identified patients who underwent isolated CABG at Mayo Clinic between January 1993 and December 2019. The CABG operation was deemed emergent if it fulfilled one of the STS emergent status criteria: Patients who have ongoing, refractory, unrelenting cardiac compromise, with or without hemodynamic instability, and not responsive to any form of therapy except cardiac surgery.11 Chart review was utilized to determine reasons for emergent referral to CABG. Those were grouped into
Results
A total of 14,455 patients who underwent isolated CABG between 1993 and 2019 were included. Of those, 427 (2.95%) were emergent operations. The number of emergent CABG decreased from 222 between 1993 and 2000, to 150 between 2001 and 2010, and 55 between 2011 and 2019. The proportion of emergent CABG to all isolated CABG also decreased from 6.4% in 1993 to 2.1% in 2019, p trend <0.001 (Figure 1). There was no change in mean age, proportion of females, and the prevalence of hypertension,
Discussion
The management of coronary artery disease has evolved considerably in the last few decades CABG remains the mainstay revascularization option for patients with severe left main multi-vessel coronary disease. Although CABG is performed with low morbidity and mortality in the vast majority of patients in contemporary practice, concerns remain about the outcomes of patients who are referred emergently for unplanned surgery.12,13 However, contemporary data on the incidence, characteristic and
