AB0725 ASSOCIATION BETWEEN RADIOGRAPHIC PROGRESSION AND CARDIOVASCULAR RISK IN SPONDYLOARTHRITIS: DATA FROM COSPAR REGISTRY

Background: Studies suggest that radiographic damage is associated with cardiovascular (CV) risk in axial spondyloarthritis (axSpA). However, the relationship among disease characteristics directly related to structural damage and CV risk has not yet been fully clarified. Objectives: To analyze the association of structural damage with the presence of atherosclerotic plaques via carotid ultrasound (US) and the increased CV risk in a registry of patients with SpA. Methods: Eighty-five patients with SpA (ASAS criteria) from the SpA registry from Cordoba (CoSpaR) were selected for a cross-sectional study and underwent a complete clinical history, physical examination and biochemical analysis. Variables about demographics, clinical parameters and CV risk factors were collected. CV risk was evaluated by estimating SCORE index and assessing presence of atherosclerotic plaques through carotid US performed by a qualified radiologist. Independent-samples t test was used to evaluate the association between radiological characteristics and presence of atherosclerosis. Multiple lineal regression (MLR) was performed to assess the variables potentially associated with increased SCORE. All comparisons were bilateral. Results: Baseline characteristics are shown in the table. Values are mean±SD for quantitative and N (%) for qualitative variables. Regarding characteristics related with radiographic damage and CV risk, they exhibited a mSASSS of 14.84±18.4 (7.27±9.64 in cervical spine and 7.72±10.14 in lumbar spine). Average BMI 26.88±4.13, 33 (38.8%) were smokers, 16 (18.8%) had diagnosis of arterial hypertension, 1 (1.2%) of diabetes mellitus, 13 (15.3%) of hyperlipidemia, and 8 (9.4%) took lipid lowering drugs. Examination with carotid US found that 14 (16.5%) patients had previously unknown atherosclerotic plaques. After classification according to SCORE index, 60 (76.9%) had low CV risk, 10 (12.8%) moderate, and both high and very high CV risk categories had 4 (5.1%) patients each. In patients with atherosclerotic plaques, age, disease duration and variables related to radiographic damage (mSASSS [total, cervical and lumbar], and bone bridges) were significantly higher (p Conclusion: Presence of atherosclerosis is associated with age, disease duration and radiographic damage in SpA. Age and structural damage especially in the cervical spine predicted a greater CV risk. Thus, it is important to identify these patients in order to maintain tight control and avoid development of CV disease.
