Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease, with progressive joint destruction, leading to disability. In half of patients, mortality is associated to coronary events, caused by classical risk factors (RF) and/or the inflammatory process. Objectives: To explore the relevance of systemic inflammatory milieu in RA without the burden of traditional RF. Methods: Women with RA and free of traditional RF (n = 30) were compared against healthy women (n = 31). Body mass index, blood pressure, glycemia, serum creatinine, total cholesterol (TC), high density lipoprotein (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG) and oxidized LDL (oxLDL), erythrocyte sedimentation rate, high-sensitivity C reactive protein (hsCRP), lipid quotients for assessing risk (TC/HDLc, LDLc/HDLc, oxLDL/non HDL cholesterol, TG/HDLc), and ultrasonographic carotid intima media thickness (IMT) were estimated or measured. Results: hsCRP and oxLDL were significantly higher in RA patients. IMT values were among normality, but thickness was slightly increased in left carotid, suggesting early atherosclerotic changes. In RA patients inflammation is associated to a higher concentration of oxLDL. No atherosclerosis was proven but a slight greater thickness in left carotid foretells the development of the disease. Conclusions: In RA patients without vascular RF, a special follow up must be implemented to halt atherosclerosis development.
