Preoperative Anemia as a Predictor of Morbidity and Mortality in Coronary Artery Bypass Grafting Surgical Patients: Our Four Years’ Experience

Abstract

Preoperative anemia is associated with increased morbidity and mortality after cardiac surgery, so we looked into the effect of preoperative hemoglobin levels on early outcome of coronary artery bypass grafting (CABG). Objective: To assess the role of preoperative anemia as a predictor of morbidity and mortality among patients who went through coronary artery bypass surgery. Methods: A retrospective study was carried out among patients who suffered from isolated CABG surgery. These patients were considered anemic with hematocrit levels less than 35.0 in females and less than 40.0 in males. The results were evaluated by using SPSS 24.0. Results: Overall mortality rate among patients who went through CABG was 3.9%. The mean hematocrit level among these patients was less than 30. Conclusions: It is concluded that the patients presented with preoperative anemia who have to undergo coronary artery bypass surgery are more likely to encounter co-morbidities and death after the surgery.
