As expected, the patients had less intraoperative total output, hypertension, higher preoperative FIB, less intraoperative total input, higher preoperative creatinine, less intraoperative autologous blood, higher NYHA score, older age, higher intraoperative minimum HCT, lower preoperative Hb, lower preoperative PLT, lower intraoperative infusion volume, higher intraoperative minimum Hb, lower preoperative HCT, higher BMI, and lower intraoperative blood loss. This evidence concerns the gene GSTM1 and Hypertension.
