Abstract

Objectives: Vascular aging and metabolic syndrome (MS) are both independent predictors of cardiovascular events. We examined whether MS accelerates the progression of vascular aging.

Methods: 142 subjects (mean age 51.9±10.8 years, 94 men) with no established cardiovascular disease were investigated in 2 examinations over a 2-year period (mean follow-up visit 1.84 years). MS was defined by the ATP III criteria. Subjects had at the beginning and end of the study determinations of carotid-femoral pulse wave velocity (PWV), aortic augmentation index corrected for heart rate (AIx75), brachial flow-mediated dilatation (FMD) and carotid intima-media thickness (cIMT). Based on these measurements the annual absolute changes were calculated.

Results: At baseline patients with MS compared with patients without MSs had lower values of FMD (6.0% vs. 7.0%, P=0.025), but there were no statistically significant differences for PWV (7.04m/s vs. 7.26m/s, P=0.242), AIx@75 (19.9% vs. 20.3%, P=0.846) and cIMT (0.68mm vs. 0.68mm, P=0.957). For the overall population, there were no statistically significant differences in the annual absolute changes of PWV, FMD, AIx75 and cIMT. However, when a subgroup of patients <60 years with more rapid progression of endothelial aging was investigated, MS was associated with almost 7 times higher annual change of FMD [−0.89% (95% CI:−1.50 to −0.28) in patients with MS vs. −0.13% (95% CI:−0.36 to 0.10) in patients without MS, P=0.032]. This difference was not evident in the other vascular biomarkers.

Conclusions: Presence of MS is associated with endothelial dysfunction as well as accelerated progression of endothelial dysfunction, especially in the younger subjects.
