Abstract
Patients and Methods: This prospective randomized controlled study included 70 IHD patients undergoing CABG surgery. It was carried out in section 24 the department of cardiothoracic surgery Faulty of Medicine Cairo University starting from August 2014 till April 2015 after obtaining the acceptance of the local ethical committee and the written consent of the study patients. Patients were divided into two matching and equally-numbered groups: group A contained 35 patients with EF >50%; while group B contained 35 patients with EF <50%. Follow-up was done for 3 months postoperatively.Results: As regards mortality in group A, 2 patients died (5.7%), while in group B 7 patients died (20.02%) (p = 0.031). In group A, the mean ICU stay time was 3.29 ± 1.49 days, versus 4.22 ± 1.98 days in group B (p = 0.028). In group A, preoperative renal dysfunctions improved in 2 patients (5.7%), versus 1 patient (2.9%) in group B patients (p = 0.555) Conclusion: We concluded that CABG in patients whose pre-operative LV ejection fraction was within normal limits (>50%) can be done more safely with better postoperative outcomes and acceptably low mortality and morbidity and operative times (surgery, CPB, ACC) as well as postoperative renal functions and ICU stay time
