Feasibility of off-pump coronary artery grafting for patients with impaired left ventricular ejection fraction: a retrospective cohort study from a single institutional database

Despite great advances in surgeries, the management of patients with impaired left ventricular ejection fraction is still challenging. Furthermore, evidences on outcomes of off-pump coronary artery bypass surgery (OPCAB) in this population are inconsistent. We conducted present study to compare the short and long-term outcomes in patients with different ejection fractions undertaken OPCAB.
