Continued low disease activity in patients with rheumatoid arthritis (RA) is associated with atherosclerosis and heart dysfunction, according to a study published in Rheumatology International.1
Patients with RA have a 2-fold higher risk for death compared with the general population, mainly because of cardiovascular disease (CVD).1 Traditional risk factors do not fully explain this increased CVD risk, and therefore, RA is considered to be an independent risk factor for CVD.2-4 High disease activity is associated with a higher incidence of CVD,5 but few data are available concerning CVD risk and heart function in patients with low disease activity.6-9 Therefore, researchers in Poland compared 70 patients with RA with continued low disease activity from 2 to 7 years and no clinically evident CVD with 33 healthy control patients of comparable age.1
The researchers found significantly greater values of carotid intima media thickness in patients with RA compared with control patients (0.83 vs 0.62 mm; P <.001), as well as a higher incidence of atherosclerotic plaques (61.4% vs 30.3%; P =.003) and prolonged corrected QT interval (439.6 vs 414.0 ms; P <.001). A high or very high risk for cardiovascular death according to the multiplied Systemic Coronary Risk Evaluation system was reported in one-third of patients with RA, and serum amino-terminal pro-brain natriuretic peptide was elevated above the normal range in almost one-fourth of patients with RA.
In addition, a strong relationship was noted between cardiovascular parameters, patient age, and disease duration. A deterioration of cardiovascular parameters was noted in patients with a higher Disease Activity Score in 28 joints, erythrocyte sedimentation rate, immunoglobulin M-rheumatoid factor concentration, and bone erosions.
“In conclusion, features of accelerated atherosclerosis and heart dysfunction were found in the group of RA patients with continued low disease activity,” stated the authors.1
