FABP4 and diabetes mellitus: Multivariable logistic regression analysis of the factors significantly associated with aortic stiffness (adopted factors: DM, age, creatinine, CRP, and A-FABP) showed that serum A-FABP level (odds ratio: 1.068, 95% confidence interval (CI): 1.017–1.121, p = 0.008) and age (odds ratio: 1.204, 95% CI: 1.067–1.359, p = 0.003) were independent predictors of aortic stiffness in patients with CABG (Table 2).
