Key result
Coronary artery bypass grafting in patients with an ejection fraction <40% was associated with more complications and an 8.3% 30-day mortality rate compared to 2.0% in patients with an ejection fraction ≥40% (p=0.126).
Why the study?
Patients with ischemic heart disease and reduced ejection fraction have increased risk for postoperative complications and mortality, warranting evaluation of the effect of low EF on early outcomes and mortality predictors after CABG.
Does low ejection fraction (<40%) increase early mortality and postoperative complications in patients undergoing elective CABG compared to those with EF ≥40%?
Cohort (n=170)
Yes
Does low ejection fraction (<40%) increase early mortality and postoperative complications in patients undergoing elective CABG compared to those with EF ≥40%?
Answers are grounded in this paper and cite their sources.
CABG in patients with EF <40% is associated with higher early complications and resource utilization compared to those with preserved EF, though clinical symptoms and echocardiographic parameters significantly improve postoperatively.

ELShafey et al. (2020) conducted a cohort in Ischemic heart disease (n=170). Coronary Artery Bypass Graft (CABG) in patients with EF < 40% vs. CABG in patients with EF ≥ 40% was evaluated on 30-day mortality (p=0.126). Coronary artery bypass grafting in patients with an ejection fraction <40% was associated with more complications and an 8.3% 30-day mortality rate compared to 2.0% in patients with an ejection fraction ≥40% (p=0.126).
