Cím:	Increased arterial stiffness as the marker of vascular involvement in systemic sclerosis / Tímár O., Soltész P., Szamosi S., Dér H., Szántó S., Szekanecz Z., Szücs G.
Dátum:	2008
Megjegyzések:	OBJECTIVE: Endothelial dysfunction and vasculopathy of the small and large vessels are crucial pathogenic factors in systemic sclerosis (SSc). Accelerated atherosclerosis and impaired flow-mediated vasodilation have been described in SSc. We evaluated arterial stiffness in patients with SSc compared to healthy controls. METHODS: Augmentation index (AI) and pulse wave velocity (PWV) of the brachial artery were measured in 40 patients with SSc and 35 age and sex matched healthy controls using an arteriograph system. RESULTS: AI was significantly higher in SSc patients (9.02) compared to controls (-41.15) (p < 0.0001). PWV was similarly higher in patients with SSc (9.67 m/s) than in controls (8.00 m/s) (p = 0.0017). PWV was significantly higher in patients with localized SSc (10.04 +/- 2.01 m/s) compared to those with diffuse SSc (8.39 +/- 1.87 m/s) (p = 0.034). There was a significant, positive linear correlation between AI and PWV (r = 0.32, p = 0.045). We also observed significant correlations between AI and age (r = 0.31, p = 0.048), PWV and age (r = 0.36, p = 0.021), and PWV and disease duration (r = 0.40, p = 0.011) in SSc patients. CONCLUSION: Increased AI and PWV of the aorta in comparison to age and sex matched healthy controls indicate increased large-vessel stiffness in patients with SSc. PWV and AI are reproducible indicators of the presence and degree of arterial stiffening. Because arterial stiffness may correlate with disease duration and age in patients with SSc, it may be a useful diagnostic test in the assessment of arterial function. Increased vascular stiffness may be therapeutically targeted by statins and other vasoprotective agents during the management of SSc.
