Blood transfusion, bleeding, anemia, and survival in patients with acute myocardial infarction: FAST-MI registry

In this cohort, anemia on admission and bleeding during hospitalization were both associated with increased 5-year mortality in patients with myocardial infarction. Conversely, transfusion per se was not associated with lower survival. Further work is needed to clarify the optimal transfusion strategy in patients with bleeding or anemia and myocardial infarction.
