Key result
Higher CRP linked to ~47% higher odds of combined carotid plaque and LV remodeling in RA.
Why the study?
Conventional CV risk scores may not adequately reflect subclinical structural CV involvement in patients with rheumatoid arthritis, where increased CV risk is driven by both traditional risk factors and chronic systemic inflammation.
Do conventional cardiovascular risk scores adequately capture inflammation-associated combined vascular and ventricular phenotypes in patients with rheumatoid arthritis without prior cardiovascular disease?
Cross-Sectional (n=195)
Do conventional cardiovascular risk scores adequately capture inflammation-associated combined vascular and ventricular phenotypes in patients with rheumatoid arthritis without prior cardiovascular disease?
Approximately two-thirds of rheumatoid arthritis patients with subclinical combined carotid plaque and left ventricular remodeling—an inflammation-associated phenotype—are missed by conventional cardiovascular risk scores, suggesting a role for imaging-based risk stratification.

Combined phenotype associated with CRP in RA; hypothesis-generating for whether inflammation-informed phenotyping refines CV risk detection beyond standard scores.
Background Rheumatoid arthritis (RA) is associated with increased cardiovascular (CV) risk driven by both traditional risk factors and chronic systemic inflammation. Conventional CV risk scores may not adequately reflect subclinical structural CV involvement in this population. Purpose To characterize vascular and ventricular phenotypes in RA and evaluate their association with systemic inflammation and estimated CV risk. Methods In this cross-sectional study, 195 patients fulfilling 2010 ACR/EULAR RA criteria and without prior CV disease underwent carotid ultrasound and transthoracic echocardiography. Carotid plaque was defined as a focal wall thickening >50% relative to adjacent wall, or a focal protrusion > 1.5 mm. Left ventricular (LV) geometry was classified according to ASE/EACVI criteria. Patients were categorized into four phenotypes: no structural involvement, isolated carotid plaque, isolated LV remodeling (abnormal geometry), and combined phenotype. High estimated CV risk was defined as QRISK3 ≥20%, EULAR-adjusted Framingham BMI ≥20%, and SCORE2 High/Very High per ESC 2021 thresholds. Framingham BMI risk estimates were multiplied by 1.5 according to EULAR recommendations. Multivariable logistic regression models compared each phenotype with the no structural involvement group, adjusting for age, sex, hypertension, and log-transformed C-reactive protein (CRP). Results Among 195 RA patients, 53 had no structural involvement, 30 isolated plaque, 58 isolated remodeling, and 54 (28%) combined phenotype. Patients with the combined phenotype were older than other groups (61 ± 7.3 vs 51 ± 9.9, 55 ± 10.4, and 53 ± 8.8 years, p < 0.001). CV comorbidities and RA characteristics were similar across groups. High estimated CV risk was identified in 33% of patients with combined phenotype by both SCORE2 and Framingham BMI. Accordingly, approximately two-thirds of patients with combined phenotype were not classified as high risk. In isolated phenotypes, Framingham BMI identified the highest proportion of high-risk patients in the remodeling group (15%), while SCORE2 identified the highest proportion in the plaque-only group (14%). This discordance persisted despite comparable distributions of traditional CV risk factors across groups. In multivariable analysis, isolated plaque was independently associated with hypertension (OR 3.28, 95% CI 1.09–10.15, p = 0.035). Isolated remodeling showed no independent associations. The combined phenotype was independently associated with higher log-CRP (OR 1.47, 95% CI 1.03–2.09, p = 0.031) and age (OR 1.16 per year, p < 0.001). Conclusion The coexistence of carotid plaque and LV remodeling identifies an inflammation-associated combined vascular and ventricular phenotype in RA. However, most patients with combined subclinical involvement were not classified as high risk by conventional scores. Imaging-based phenotyping may complement CV risk stratification in RA.

Ramirez et al. (2026) conducted a cross-sectional in Rheumatoid arthritis (n=195). Higher log-transformed C-reactive protein (CRP) vs. No structural cardiovascular involvement was evaluated on Combined vascular and ventricular phenotype (carotid plaque and left ventricular remodeling) (OR 1.47, 95% CI 1.03-2.09, p=0.031). Higher log-CRP was independently associated with a combined carotid plaque and LV remodeling phenotype in RA (OR 1.47; 95% CI 1.03–2.09; p=0.031), though only 33% were classified as high CV risk.
