Preoperative anemia affects up to 50% of patients undergoing cardiac surgery.

Perioperative Anemia and Patient Blood Management in Cardiac Surgery: A Scientific Statement From the American Heart Association.

Kimberly Howard-Quijano et al. · Circulation · 2026
Background

Perioperative anemia and red blood cell transfusions are important risk factors for morbidity and mortality in cardiac surgery.

Purpose

Strategies aim to reduce blood loss and transfusions and improve patient outcomes.

50%
Results
up to half of heart surgery patients have low red blood cells before surgery
More results

There has been a recent increase in research related to anemia, iron deficiency, and patient blood management in cardiac surgery.

“
Conclusion

This scientific statement highlights the latest evidence on preoperative anemia assessment and intraoperative blood conservation; discusses considerations for specific patient populations regarding anemia prevalence, treatment, and outcomes; and reviews key challenges and knowledge gaps, with the goal of minimizing the impact of preoperative anemia, intraoperative blood loss, and hemodilution on cardiac surgery outcomes.
