found that an increased rate of AKI was also observed in patients who had a severe postoperative Hb reduction (>4 g/dL) compared to those with a moderate (2–4 g/dL) or mild Hb reduction (<2 g/dL) for type B aortic dissection patients who underwent TEVAR (OR, 4.34, 95% CI, 1.91–9.85, p < .001) [40]. The gene discussed is GSTM1; the disease is Aortic dissection.
