Background: To evaluate the association between hypertriglyceridemic waist (HTGW), a promising marker of visceral adiposity and cardiovascular (CV) risk, and different indicators of vascular damage in type 2 diabetes (T2D) patients. Methods: This case-control study included 161 patients with T2D (91 males, 70 females) and 40 healthy controls (24 males, 16 females). HTWG was defined as waist circumference >90 cm in men or >85 cm in women and triglyceride concentrations >2 mmol/L. In addition to anthropometric and metabolic parameters, markers of endothelial dysfunction, namely von Willebrand factor (vWF) and plasminogen activator inhibitor-1 (PAI-1), were assessed. Arterial stiffness parameters were examined using the SphygmoCor system. Results: Individuals with T2D and HTGW showed the highest elevation of PAI-1 levels and significantly increased vWF levels compared with healthy controls. No significant differences in arterial stiffness markers were observed between T2D individuals. Age and, for several markers, systolic and/or diastolic blood pressure were identified as the main predictors for arterial stiffness, whereas PAI-1 and vWF levels were predicted by metabolic parameters. Conclusions: HTGW represents increased CV risk in T2D patients, mainly due to endothelial damage. The presence of HTGW had no significant effect on arterial stiffness compared with other T2D individuals.
