The Cardiovascular Burden of Rheumatoid Arthritis - Implications for Treatment.

ABSTRACT

Mortality in rheumatoid arthritis is increased, about twice vs controls, and cardiovascular diseases are a major cause. The pathogenesis is primarily accelerated atherosclerosis of the coronary, cervical, and cerebral arteries, which is premature, pervasive, and progressive, but often occult, under-recognized, and under-treated. It is mostly driven by the chronic, systemic autoimmune inflammation, but increased prevalence of traditional risk factors and adverse effects of treatments are also very important. Inflammatory markers, disease severity, and duration are major determinants of the cardiovascular risk in rheumatoid arthritis, which is underestimated by usual methods. Cardiovascular protection is best achieved by suppressing inflammation and disease activity as early as possible ("treat-to-target"), and striving to achieve and maintain remission or lowest disease activity. Secondly, identifying and addressing the whole spectrum of traditional risk factors, currently often neglected, is necessary. Because long-term glucocorticoid exposure ≥5 mg/d may be associated with cardiovascular events and other harm, more intensive treatment, especially useful for bridging with methotrexate at the outset of treatment, needs to be limited in time and dosage. A multipronged approach may improve cardiovascular outcomes of RA patients in future studies.
