Cardiovascular risk in rheumatoid arthritis: effects of anti-TNF drugs.
BACKGROUND
Patients with rheumatoid arthritis (RA) have an increased risk of atherosclerotic cardiovascular disease which cannot be explained by traditional cardiovascular risk factors alone. Atherosclerosis is considered an inflammatory condition and inflammation experienced in RA may contribute to accelerated atherosclerosis. Thus, it should be hypothesized that treatment with antitumor necrosis factor alpha (anti-TNF-alpha), TNF-alpha being a pivotal component of the inflammatory cascade, may decrease concomitantly intra-articular inflammation and vessel inflammation.


OBJECTIVE
The purpose of this review is to examine the data regarding cardiovascular mortality and morbidity in RA and the evidence available to date evaluating the influence of anti-TNF-alpha treatments in RA on the occurrence of cardiovascular events, on surrogate markers of atherosclerosis and classical cardiovascular risk factors.


METHODS
Clinical trials, original studies and review articles were identified from a Medline search (1998 - December 2007). Articles in English were reviewed, with emphasis on those containing assessments of cardiovascular effects (i.e., biological, structural, clinical) of anti-TNF-alpha drug.


CONCLUSIONS
The suppression of systemic inflammation favoring atherosclerosis may lead to an improvement in cardiovascular prognosis in inflammatory disorders. Thus, reduction of inflammatory joint disease in RA with anti-TNF-alpha therapy, as probably with any powerful disease-modifying antirheumatic drugs, seems to be, at least in part, associated with concomitant reduction of the risk of cardiovascular events.
