Aim. The aim of this study was to evaluate the association between arterial stiffness and albuminuria and glomerular filtration rate (GFR) in patients with type 2 diabetes mellitus.Methods. This multicenter cohort study analyzed 2613 patients with type 2 diabetes. Brachial-ankle pulse wave velocity (baPWV) was used as a noninvasive marker of arterial stiffness. Additionally, the patients were categorized into four groups according to their albumin-to-creatinine ratio (ACR, normoalbuminuria versus albuminuria) and estimated GFR (eGFR, <60 mL/min/1.73 m2versus ≥60 mL/min/1.73 m2).Results. A univariate analysis revealed that maximal baPWV was significantly associated with both the ACR ( r=0.297 , P<0.001 ) and eGFR ( r=−0.220 , P<0.001 ). A multivariate analysis adjusted for significant clinical variables and eGFR showed that baPWV remained significantly correlated with the ACR ( r=0.150 , P<0.001 ). Also, baPWV was correlated positively with the ACR in patients with an eGFR ≥ 60 mL/min/1.73 m2( r=0.146 , P<0.001 ). However, baPWV was not correlated with eGFR after adjustment for significant clinical variables.Conclusions. The present findings indicate that arterial stiffness is more associated with albuminuria than a decrease in GFR in patients with type 2 diabetes mellitus.
