Assessment of Cardiovascular Risk in Patients With Rheumatoid Arthritis According to Current Hypertension Guidelines

Objective: Patients with rheumatoid arthritis (RA) are at increased risk of cardiovascular disease (CVD) by as much as 50% compared to the general population. Considering that disease-specific calculators have failed to provide more accurate CVD risk stratification in RA, CVD risk calculation in RA patients is challenging, especially for those who are not by definition at high risk based on concomitant established CVD or its equivalents. The presence of an immune-mediated inflammatory disease (e.g., RA) has been considered as a CVD risk modifier by the previous 2018 European Society of Hypertension/European Society of Cardiology (ESH/ESC) guidelines. Nevertheless, current 2023 ESH/ESC guidelines recommend assessment in RA using general CVD risk calculators. Design and method: We aimed to calculate CVD risk in RA patients using the most frequently applied CVD risk calculators in the general population. We only stratified patients free from established CVD (heart disease, stroke) or its equivalents (diabetes mellitus, chronic kidney disease) aged 40-74 years. The following algorithms were applied: (i) SCORE2 (Systemic Coronary Risk Estimation-2), (ii) Framingham Risk Score-Adult Treatment Panel (FRS-ATP) CVD risk calculator, and (iii) the American College of Cardiology/American Heart Association (ACC/AHA) Pooled Cohort Equation. We further correlated the estimated CVD risk by each algorithm with surrogate CVD markers, i.e. arterial stiffness and carotid atherosclerosis. For this purpose, carotid-femoral pulse wave velocity (cfPWV) was measured using applanation tonometry (Sphygmocor ®), and carotid intima-media thickness (cIMT) was estimated using carotid ultrasound. Results: A total of 91 patients aged 60.3±8.1 years were included (78% females). Using the FRS-ATP algorithm, more patients were classified as high risk and fewer as low risk compared to the other calculators (Table 1). Moreover, CVD risk calculated with FRS-ATP correlated stronger with both cfPWV and cIMT, compared to CVD risk calculated with the other algorithms (Table 2). Conclusions: In RA patients without established CVD, diabetes, or chronic kidney disease, the FRS-ATP algorithm may be applied as a useful tool for CVD risk stratification. Prospective, large-scale studies are warranted to determine the most reliable CVD risk prediction model for patients with RA.
