Abstract: The value of ultrafast pulse wave velocity (UFPWV) technique in quantitative evaluation of carotid elasticity in systemic lupus erythematosus (SLE) patients with different carotid intima-media thickness (IMT) was studied. A total of 52 SLE patients were selected and divided into carotid IMT normal group (32 cases) and carotid IMT thickening group (20 cases) according to IMT thickness. Thirty healthy volunteers were selected as healthy group. The results showed that the values of Ds, Dd, β, EP and PWVβ in patients with thickened carotid artery IMT were higher than those in carotid IMT normal group and healthy group (P<0.05).PWVBS and PWVES of patients with carotid IMT thickening group were higher than those of healthy group and carotid IMT normal group (P<0.05). The above research shows that UFPWV technology has important value in evaluating carotid elasticity changes in SLE patients with different carotid IMT, and has certain guiding significance in clinical evaluation of vascular wall lesions in SLE patients.
