Blood Transfusion in Patients With Acute Myocardial Infarction, Anemia, and Heart Failure: Lessons From MINT

Circ Heart FailPublished trial

Authors' conclusion

A liberal transfusion strategy is safe for patients with MI and anemia, including those with baseline HF. Restrictive transfusion tended to result in worse outcomes, particularly in patients with baseline HF.

Study context

Population
Patients with myocardial infarction (MI) and anemia (hemoglobin <10 g/dL), with and without baseline heart failure (HF)randomized patients with MI and anemia
Participants
3,504 patients
Comparison
We compared the effects of transfusion strategy on outcomes among patients with and without baseline HF
  • Baseline HFn = 1,871
  • Without baseline HFn = 1,633
Primary endpoint
death or HF
Follow-up
30 days
Methodological detailsrandomized
  • Randomized

  • HF: patients without baseline HF; lower with restrictive transfusion
  • HF: P interaction =0.02

Death or recurrent MI; death (secondary outcomes)

More frequent among those with baseline HF
Restrictive transfusion resulted in numerically higher rates of death or MI and death in patients with than in those without baseline HF

HF

Rates of HF similar between restrictive and liberal transfusion in patients with baseline HF
