Background:Numerous studies have shown that the life expectancy of patients with spondyloarthritis (SPA) is, on average, 5-7 years less compared to the population, and the overall mortality rate is 1.6-1.9 times higher than the population, while mortality from cardiovascular disease increases by 20-40%.Objectives:of the current study were to assess the cardiovascular risk in pts with with ankylosing spondylitis, psoriatic arthritis and psoriatic spondyloarthritis and to compare different cardiovascular risk scales in these pts.Methods:The study included 54 patients with SpA aged 45 to 65 years. The patients were divided into 3 groups: patients with ankylosing spondylitis (AS) who meet the modified New York criteria for AS (1984) (n = 14), patients with psoriatic arthritis (PsA) who meet the CASPAR criteria (Classification criteria of Psoriatic Arthritis, 2006) (n = 18) and patients with psoriatic spondyloarthritis (PsSpA) meeting the modified New York criteria for AS and CASPAR criteria for PsA (n = 22).The average age in the AS group was 55.5 ± 6.43 years, in the PsA group - 57.4 ± 5.76 years, in the PsSpA group - 55.0 ± 6.45 years. Men made up 64.3% in the AC group, 50% in the PsA group, and 49% in the PsSpA group.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.After the numerical assessment of the indicators, each patient was graded in the degree of CVR with the allocation of low, medium, high and very high degree. To stratify the degrees, an estimate of the total risk on the SCORE scale was used: with a value of less than 1%, the risk was considered low, from> 1% to 5% - medium or moderately increased, from> 5% to 10% - high, and> 10% - very high.Results:The values of the indices were in the AS group SCORE – 3,05±2,41%, RRS – 5,05±2,67%, QRISK3 – 6,68±3,11%, in pts with PsA SCORE - 4,11±2,22%, RRS - 5.72 ± 2.46%, QRISK3 - 7.25 ± 2.51% and in pts with PsSpA SCORE - 4.78 ± 2.65%, RRS - 6.35 ± 2.34 %, QRISK3 - 8.02 ± 3.25%.Table 1.The number of pts corresponding to different degrees of risk depending on the used CVD risk assessment scale, n = 54Degrees of riskSCORERRSQRISK3Low920Medium322616High122328Very high1310When assessing CVR using various risk assessment scales (RRS, QRISK3, SCORE), the highest values were obtained in the PsSpA group.When comparing the results obtained, it was found that the majority of the surveyed belonging to a low degree of CVR according to SCORE (9 people), when evaluated using other scales, fell into the group of medium or high risk. The assessment of the risks of 10-year significant cardiovascular events in patients with SPA using the SCORE index does not coincide with the QRISK3 index data in 70.4% of cases, with the RRS data - in 42.6% of cases, and the SCORE index shows lower values of the expected risk. The highest values were obtained when assessing CVR using the scale QRISK3.Conclusion:The highest CVR values were obtained in the PsSpA group using various risk assessment scales (RRS, QRISK3, SCORE). There was a discrepancy in the severity of CVR calculated using different rating scales in SpA patients. The largest values were obtained when using the scale QRISK3, and the smallest when calculating the CVR using the scale SCORE.References:[1]Horreau C, Pouplard C, Brenaut E, Barnetche T, Misery L, Cribier B, et al.
