Three suspected risk factors for CI-AKI identified using univariate analysis were diabetes mellitus, evolocumab use, and Killip class I. Regression analysis was performed on these three factors and other clinically recognized factors affecting CI-AKI occurrence [15], including advanced age (>70 years), previous myocardial infarction, diabetes, hypertension, anemia (Hb level <110 g/L), contrast agent dose >150 mL, LVEF <45%, and emergency PCI. This evidence concerns the gene GSTM1 and hypertensive disorder.
