Outcome of coronary artery bypass graft surgery in patients with low ejection fraction

Background: Patients with low ejection fraction (EF) are at high risk for postoperative complication and mortality. Our aim was to assess the effect of low EF on clinical outcome after surgery. Objective: The present study evaluates our experience with coronary artery bypass grafting in patients with low EF. Materials and Methods: We analyzed the data of 35 patients with EF <35%. All participants were assessed preoperatively with respect to patient characteristics, risk factors, and preoperative two dimension echocardiography (2D ECHO). Depending on findings of 2D ECHO patients were divided into three groups: in Group 1, we included patients with EF 30%–35%, Group 2 comprised patients with EF of 25%–30%, and Group 3 consisted of patients with EF
