Background: Cardiovascular disease (CVD) is the most considerable long-term outcome of rheumatoid arthritis (RA) and the leading cause of premature death in RA patients. The pathogenesis of CVD in RA is largely determined by persistent systemic inflammation and its underlying factors, including chemokines. In this regard, C-X-C motif chemokine ligand 12 (CXCL12) has a crucial role in the CVD and RA pathogenesis. For the first time, plasma CXCL12 was related to conventional CV risk and well-established cardiac biomarkers in RA patients. Methods: This study was conducted on 30 RA patients who have been newly diagnosed, 30 under-treatment RA patients, and 30 healthy subjects. The plasma levels of CXCL12 and N-terminal pro-B-type natriuretic peptide (NT-ProBNP) were measured using the enzyme-linked immunosorbent assay (ELISA) technique. The high sensitivity C-reactive protein (HS-CRP) concentration was evaluated in plasma samples using the ADVIA 1800 Clinical Chemistry System based on the latex-enhanced immunoturbidimetric assay. The CVD risk was measured by calculating the Framingham risk score (FRS) and systematic coronary risk evaluation (SCORE). Results: The mean FRS and plasma concentration of high-density lipid (HDL), NT-proBNP, and HS-CRP were significantly different between the three groups (P = 0.029, P < 0.001, P = 0.016, P < 0.001, respectively). A significant positive correlation was found between CXCL12 with disease activity score-28 (DAS-28) (P = 0.024, r = 0.293) and NT-proBNP (P < 0.0001, r = 0.570) in the patients’ group. Conclusions: Based on the results, there was a significant relationship between the inflammatory mediator CXCL12 and a well-known cardiac biomarker, NT-proBNP.
