We read with interest the meta-analysis of Chatterjee and colleagues,1 which reports higher rates of mortality and myocardial reinfarction in patients with myocardial infarction (MI) receiving a blood transfusion. These findings can be added to previous evidence for a restrictive transfusion policy in critically ill patients. As a possible mechanism for the association between transfusion and reinfarction in their meta-analysis, the authors suggest triggering of platelet aggregation by red blood cell transfusion.2
