Prognostic Impact of Anemia and Blood Transfusions on Cardiovascular Outcomes in Patients Undergoing Vascular Surgery: A Scoping Review
Authors' conclusion
The weight of the evidence suggests that anemia carries a substantial burden of cardiovascular complications, mortality, and multiorgan complications, resulting in increased health care costs.

Main finding
As reported in the abstract
- Anemia definition varied, mainly based on hemoglobin cut-off levels
- Anemia associated with older age, coronary artery disease, hypertension, DM and other comorbidities
- In peripheral and endovascular aortic surgery, anemia consistently linked with higher mortality, MACE and other postoperative complications (respiratory, renal, surgical site infections, longer hospital stay), depending on hemoglobin levels
- Anemia is an important predictor of transfusions
- Transfusions in anemic patients associated with increased mortality, postoperative complications and need for major amputation
- 15 retrospective and 6 observational prospective studies
