Is There Any Relationship between Joint Destruction and Carotid Intima-media Thickness in Patients with Rheumatoid...

[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.
