GSTM1 and anemia (phenotype): Regarding the postoperative laboratory values, anemia and elevated lactate and creatinine levels were also more frequent in the secondary aortic group when compared to the primary aortic group (Hb 5.93 (±0.9) vs. 5.65 (±0.071) mmol/L, p = 0.9, 97.2 (±47.8) vs. 44.5 (±20.5), p = 0.614, and 4.1 (±4.7) vs. 1.15 (±1.43) umol/L, p = 0.233).
