Background: High Resolution sonography of common carotid artery is a safe method for rapid diagnosis of atherosclerosis in Rheumatoid Arthritis (RA). The purpose of this study was to compare sonographic findings of subclinical atherosclerosis in rheumatoid arthritis patients and control group and comparing the prevalence of atheromatous plaques and Intima- media thickness in arteries of the groups.

Methods: Fifty RA patients and fifty non-RA persons were evaluated in a cross- sectional, Descriptive study. The sonographic findings of common carotid artery of these two groups were compared.

Results: After analysis of the sonographic findings of common carotid arteries of 100 females in our study (50 patients with the mean age of 48.1y/o [23-61] and 50 control group with the mean age of 47y/o [23-61]), the prevalence of RA patients with atheromatous plaques was 32% and in control group was 6%. [OR=7.4, 95%CI=2-27.3, p=0.001]. The mean (SD) of the Intima- Media Thickness (IMT) in RA patients was 7.76 mm (1, 04) while in control group was 6.10 mm (0.95). From 38 RA patients with less or equal 5 joints involvement in hand radiography, 13.2% had atheromatous plaques and the mean (SD) of the IMT was 7.6 (±1.1) mm. From 12 patients with more than 5 joints involvement in radiography, 91.7% had atheromatous plaques and the mean (SD) of the IMT was 8.4 (±0.7) mm. [p=0.012].

Conclusions: Regarding higher prevalence of vascular problems in RA patients, screening and early diagnosis of vascular pathologies could be of value in reducing morbidity and mortality of these patients.
