Our model incorporates nine predictive factors (Vlisides and Moore, 2021): age, drinking history, diabetes, angina pectoris, cerebrovascular disease history, intraoperative MAP ≤60 mmHg for 5–10 min, preoperative blood sodium level, preoperative ACE inhibitor use, and perioperative NSAID use. This evidence concerns the gene ACE and angina pectoris.
