Open Access Abstract Introduction Patients with recent-onset rheumatoid arthritis RA have impaired brachial artery endothelial function compared with controls matched for age sex and cardiovascular risk factors. The present study examined endothelium-dependent flow-mediated dilatation FMD and independent glyceryl trinitrate GTN -mediated dilatation GMD structural responses in early RA patients and determined progress over one year. Methods Brachial artery FMD and GMD and carotid intima media thickness cIMT were studied using ultrasound in 20 patients diagnosed with early RA in whom symptoms had been present for less than 12 months and in 20 control subjects matched for age sex and established cardiovascular risk factors. FMD and GMD were re-assessed after 12 months in RA patients and the change in each parameter was calculated. Data were
