Binary logistic regression analysis was conducted with the presence or absence of postoperative cerebral infarction as the dependent variable, and variables with significant statistical significance in the univariate analysis (eccentricity, remodeling index, blood glucose, HA), and potentially clinically significant independent variables (Age, Diabetes, Syndecan‐4, HS, Biglycan) as independent variables. This evidence concerns the gene BGN and brain infarction.
