The ROC curve analysis indicated that both plasma Gal-3 (area under curve AUC) (C index) = 0.756, 95% confidence interval (CI):0.650–0.861, p < 0.001) and LAD (AUC = 0.763, 95% CI 0.645–0.880, p < 0.001) were strong independent predictors of NOAF diagnosis after MI during hospitalization (Fig. 1). Here, LGALS3 is linked to myocardial infarction.
