Carotid intima media thickness in rheumatoid arthritis patients compared with matched healthy control individuals. The carotid intima media thickness (IMT) is increased in rheumatoid arthritis (RA) patients compared with healthy control individuals matched for age, sex and cardiovascular risk factors. Representative carotid ultrasound images from three matched RA patient and control individual pairs: (a) a 42-year-old male with RA and a 40-year-old control male, (b) a 58-year-old male with RA and a 58-year-old control male, and (c) a 31-year-old female with RA and a 31-year-old control female. The automated measurement lines over the region of interest are boxed (in blue).
