POS1019 INCONSISTENCY OF THE DEGREE OF CARDIOVASCULAR RISK WHEN ASSESSED USING DIFFERENT INDICES IN PATIENTS WITH AXIAL SPONDYLOARTHRITIS
Background:Evaluation of indicators of cardiovascular risk is one of the main tasks facing a rheumatologist in the tactics of choosing a therapy for patients (pts) with axial spondyloarthritis (axSpA). It is known that pts suffering from axSpA are characterized by a significant increase in cardiovascular risk (CVR). However, there are still no recommendations regulating risk assessment scales in pts with axSpA.Objectives:were to assess the CVR in pts with axSpA and to compare different cardiovascular risk scales in these pts.Methods:The study included 55 pts at the age of 45-65 years with diagnosis of axSpA fulfilling ASAS criteria (2009) from St. Petersburg’ axSpA register. Three indices of cardiovascular risk evaluation (Systematic COronary Risk Evaluation (SCORE) with increasing coefficient 1.5 for inflammatory diseases, Reynolds Risk Score (RRS), and the third modification of QRESEARCH Cardiovascular Risk Algorithm (QRISK3) were calculated. Risk gradation: low risk (<1%), medium (1.0-4.9%), high (5.0-9.9%), very high (> 10%).Results:Mean age of the pts was 45.8±10.3 years; males - 37 (67.3%) pts, HLA-B27 positive – 34 (61.8%); mean disease duration 12.5±8.7 years. Mean value of SCORE was 2.83±1.89%, of RRS – 5.04±3.98%, of QRISK3 – 7.91±4.91%.The gradation of the degree of risk depending on the applied assessment index is presented in Table 1.IndexResultsRisk degreeSCORERRSQRISK3Low21 (38,2%)8 (14,5%)0 (0,0%)Medium26 (47,3%)23 (41,8%)17 (30,9%)High8 (14,5%)17 (30,9%)22 (40,0%)Very high0 (0,0%)7 (12,7%)16 (29,1%)Particular attention is drawn to the 100% discrepancy of low risk values when comparing SCORE and QRISK3. A similar trend persisted when comparing medium, high and very high risk. Thus, the assessment of the risks of 10-year significant cardiovascular events in pts with axSpA using the SCORE index does not coincide with the QRISK3 index data in 87.27% of cases, and with the RRS data - in 58.18% of cases. In 84.3% of cases, the mismatch between the SCORE and RRS indexes was due to the presence of an increased CRP level.Conclusion:When assessing cardiovascular risk in pts with axial spondyloarthritis, a discrepancy was found between the degrees of risk when assessed using different scales. SCORE scores were significantly different from Reynolds’ and QRISK3 scores. These features can be interrelated with a small number of factors assessed when calculating the SCORE, even though there is a correction factor for rheumatic diseases. For pts with axial spondyloarthritis, it is necessary to use additional indicators that influence cardiovascular risk, such as CRP.Disclosure of Interests:None declared.
