[Purpose] The purpose of this study was to investigate the possible relationship between
joint destruction and carotid intima-media thickness in patients with rheumatoid
arthritis. [Subjects and Methods] Thirty-four RA patients and 31 healthy controls were
enrolled in this study. The disease activity for 28 joints was recorded for each patient
using the erythrocyte sedimentation rate (DAS28ESR), a visual analog scale
(VAS0–10 cm), and a disability index, the health assessment questionnaire
(HAQ). X-ray imagesof the patients were scored according to the modified Sharp/van der
Heijde method, and the common carotid intimal medial thickness (CIMT) was automatically
measured with software using high-resolution Doppler ultrasound. [Results] Contrary to our
hypothesis, the modified total Sharp score (mTSS) and CIMT were not significantly
associated. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels
of the RA patients and the right CIMT, left CIMT, and mean CIMT scores were significantly
elevated. Positive correlation was detected between the mean CIMT score and age, CRP
levels, LDL concentration and triglycerides (TG) level. In the regression model, where the
mean CIMT was the independent variable and age, CRP, LDL, and TG were dependent variables,
age was found to be an independent predictor of CIMT. [Conclusions] Patients suffering
from RA require close monitoring for cardiovascular risks, and the comorbidity of
age-related cardiovascular disease should not be overlooked.
