Effect of tumor necrosis factor a inhibitors on heart failure risk in RA Patients

A chronic autoimmune disease, rheumatoid arthritis (RA) is characterized by persistent inflammation of the synovial membrane and progressive joint destruction. Beyond loss of mobility, sufferers face a high risk of heart failure. An inflammatory cytokine known for contributing to the development of RA, tumor necrosis factor a (TNFa) has also been implicated in cardiovascular disorders. Inhibition of TNFa has opened promising new treatment options for RA patients. Anti-TNF drugs such as infliximab, etanercept, and adalimumab have been shown to not only diminish signs and symptoms of the disease, but also prevent joint damage. However, in cardiac trials, TNFa inhibitors have shown no more positive effects on heart failure risk -- and sometimes less -- than placebo.
