Sabatine et al. [61] reported an increased mortality in patients with ST-elevation myocardial infarction when Hb value was > 170 g/L (OR = 1.79; 95% CI: 1.18 to 2.71, P = 0.007) and > 160 g/L (OR = 1.31; 95% CI: 1.03 to 1.66, P = 0.027) in patients with non-ST-elevation myocardial infarction. This evidence concerns the gene GSTM1 and ST Elevation Myocardial Infarction.
