【摘要】Objective To explore the clinical value of early diagnosis of atherosclerosis in patients with systemic lupus erythematosus (SLE) using vascular echo-tracking technique and to detect changes of elastieity of carotid artery quantitatively in SLE patients.Methods Fifry patients with SLE were divided into SLE1 group(duration≤1 year),and SLE2 group(duration>1 year)based on different course.An ultrasonic echo-tracking method was used to measure patients'pressure strain elastic

compliance(AC),augmentation index(AI),pulse wave velocity (PWVβ) and intimamedia thickness(IMT)of the common carotid arteries in 50 patients with SLE and in 25 healthy control subjects.Results Among carotid artery elasticity indicators of three groups,there was no significant difference in AI(P>0.05).Ep,β,PWVβ parameters of SLE1 group and SLE2 group were statistically higher than that of the control group[Ep
