A recent study demonstrates the utility of carotid-MRI in rheumatoid arthritis (RA), reporting an association between 3-dimensional measures in particular and cardiovascular (CV) risk scores, individual traditional CV risk factors, and RA disease duration. Therefore, carotid-MRI in RA is a promising research tool in the investigation of CVD. 64 patients with RA and no history of CV disease/diabetes mellitus were assessed for a RA and CV profile, including homeostasis model assessment-estimated insulin resistance (HOMA-IR) and N-terminal pro-brain natriuretic peptide (NT-proBNP). All underwent carotid-MRI (3 T), and were compared to 24 healthy controls. Researchers found:
- There were no significant differences in carotid arterial wall measurements between patients with RA and controls.
- Wall and luminal volume correlated with 10-year CV risk scores.
- In univariable analysis, carotid-MRI volumetric measures predominantly were associated with traditional CV risk factors including age, ever-smoking, and HOMA-IR.
- In multivariable linear regression models, age was independently associated with wall volume and luminal volume, and RA disease duration was associated with luminal volume.
