Investigation the Outcomes of CABG in Patients with Left Ventricular Dysfunction

Introduction: Patients presenting with severe left ventricular dysfunction undergoing coronary artery surgery are at increased risk of preoperative morbidity and mortality. Objective: Investigate the outcomes of CABG in two groups of patients. Materials and Methods: In this descriptive study 815 patients who underwent coronary artery surgery were divided to two groups: Group A, 66 cases with EF less than 40% and group B, 749 cases with EF more than 40%. Results: Most of the cases were men and their Mean age was 63 years old. Most of the cases in Group A were in class III or IV of cardiac failure before the surgery (in attention to EF reported in echocardiography). In this group mean aortic clamp time, pomp time and surgery time were more than group B. Also the evidences showed that intubations time, ICU stay and Hospitalization were more in group A. There were statistically meaningful differences between mortality (P
