Following adjustments for age, sex, dyslipidemia, cerebrovascular disease,chronic pulmonary disease, heart rate, respiratory rate, systolic blood pressure,temperature, fasting blood glucose, blood urea nitrogen, anion gap, internationalnormalized ratio, PCI, and CABG, the multivariate Cox regression analysisrevealed that the group with Hb <9 g/dL and no ID (HR 1.512, 95% CI1.031–2.217, p = 0.034) was a risk factor for all-cause mortality at120 days when compared to the reference group with Hb ≥9 g/dL and no ID(Supplementary Table 2). This evidence concerns the gene GSTM1 and cerebrovascular disorder.
