What effects might anti-TNFα treatment be expected to have on cardiovascular morbidity and mortality in rheumatoid arthritis?: A review of the role of TNFα in cardiovascular pathophysiology

Patients with rheumatoid arthritis ( RA) have an increased burden of atherosclerotic cardiovascular disease which cannot be explained by an increased prevalence of traditional cardiovascular risk factors alone. Atherosclerosis is now being viewed as an inflammatory condition and the cumulative inflammation experienced in RA may contribute to accelerated atherosclerosis. It has been hypothesised that treatment with anti-tumour necrosis factor (TNF) a in RA may reduce both intra-articular inflammation and the inflammation associated with atherosclerosis. Thus, TNF alpha blockade may reduce the cardiovascular morbidity and mortality associated with RA. This review examines the pathophysiological role of TNFa in atherosclerosis and the evidence to date that anti-TNF alpha treatment modifies this process in RA.
