It is known that patients with rheumatoid arthritis (RA) have a higher risk of coronary heart disease and sudden cardiac death. Abnormalities in cardiac geometry appear to be involved in the setting of the cardiovascular risk, but it has never been specifically investigated in RA. We enrolled 44 patients with RA compared to 131 subjects without RA (normal, N): The RA aged between 18 and 70 years (mean 48.3 ± 2.1), 25 females, BMI 27.6 ± 0.9; N, of equal age (48.6 ± 1.2, n.s.), included 80 females (BMI 26.7 ± 0.2, ns). Cardiac Ultrasounds showed an increase of the diameter of the left ventricle but not in the septum with reduction of relative wall thickness (RWT) in the RA population compared to N. Relative wall thickness inversely correlates with biochemical parameters of inflammatory response (gamma globulin, p < 0.03; F = 5,660) and anti citrullinated peptides antibody (anti-CCP Ab) (p < 0.02; F = 7,1620) We conclude that unfavorable cardiac remodeling can increase cardiovascular risk in patients with RA.
