Regarding the preoperative laboratory values, anemia and elevated lactate and creatinine levels were more frequent in the secondary aortic group when compared to the primary aortic group (Hb 6.36 (±1.1) vs. 6.62 (±1.1) mmol/L, p = 0.942, 92.1 (±43.6) vs. 80.46 (±29.1) mmol/L, p = 0.528, and 5.2 (±5.57) vs. 1.35 (±0.21) umol/L, p = 0.029). Here, GSTM1 is linked to anemia.
