Key result
A left ventricular ejection fraction of less than 40% independently predicted fatal cardiac outcomes after coronary artery bypass grafting, increasing the relative risk by 5.7 times.

What are the predictors of cardiovascular complications in patients with chronic ischemic heart disease after bypass surgery?
Answers are grounded in this paper and cite their sources.
The authors studied137 patients with coronary artery disease who underwent coronary artery bypass grafting under cardiopulmonary bypass. At follow-up for 2-5 years, deaths due to cardiac causes were recorded, including cases of sudden death, as well as the development of non-fatal cardiovascular complications.

Akhmedov et al. (2023) conducted a cohort in Chronic ischemic heart disease (n=120). Left ventricular ejection fraction <40% vs. Left ventricular ejection fraction ≥40% was evaluated on Fatal cardiac outcomes (RR 5.7, 95% CI 1.2-10.7, p=0.001). A left ventricular ejection fraction of less than 40% independently predicted fatal cardiac outcomes after coronary artery bypass grafting, increasing the relative risk by 5.7 times.
