However, studies among myocardial infarction patients have indicated that more liberal RBCT thresholds, such as transfusing at 10 g/dL Hb with a goal of Hb >11 g/dL, doesn’t significantly alter length of stay (LOS), 30-day hospital costs, among other outcomes [3]. The gene discussed is GSTM1; the disease is myocardial infarction.
