Five key findings about anemia[47]

Key	Findings
1	The preoperative HCT is a powerful independent predictor of mortality, renal failure, deep sternal wound infection, and prolonged hospital stay
2	The preoperative HCT has the greatest, and most consisted impact on the risk of renal failure
3	Elective surgical patients behaved similarly
4	For all major morbidities and mortality, there was a nadir consistently observed between HCT values of 42% and 46%
5	The likelihood of perioperative transfusion was dramatically influenced by the properative HCT
