Threshold for transfusion in ACS – Cardiology MCQ

Threshold for transfusion in anemia with acute coronary syndrome and no hemodynamic compromise:
a) <10 g/dl
b) <9 g/dl
c) <8 g/dl
d) <5 g/dl
Correct answer c) <8 g/dl
Hemoglobin <8g/dl is the usual threshold for transfusion in acute coronary syndrome without hemodynamic compromise [1]. Cause of anemia should be investigated and iron supplements can be given. But erythropoietin should be avoided because of potential thrombotic risk. Interventions with a high risk of bleeding are better avoided in those with severe anemia.
