The prevalence of anemia is high in patients undergoing cardiac surgery. There is enough evidence that the presence of anemia increases perioperative mortality and morbidity both in noncardiac and cardiac surgery. Anemia is an independent risk factor for increased blood transfusion, length of stay, morbidity, and poor outcomes. It is prudent to delay elective surgery to enhance erythropoiesis preoperatively. There is a synergistic interaction between anemia and blood transfusion in cardiac surgery resulting in worse outcomes that are greater than simply the additive effects of both conditions.
