AB0717 Conduction disturbances in a group of patients with axial spondyloarthropathy

Abstract

BackgroundCardiac conductance disturbances are known to be one of the many extra-articular manifestations of Ankylosing Spondilitis but not as well related to axial spondyloarthropathies.ObjectivesDescription of conduction disturbances found in a group of patients with Axial Spondyloarthropathy (AxSpa) that met ASAS criteria.MethodsClinical and demographic variables of 78 patients with AxSpa were registered. It included cardiovascular risk factors as well as cardiacvascular adverse events. All of them had a routine electrocardiogram done which were analized by a cardiologist.Results48 of the 78 patients were men, with a mean age of 61 with standard deviation (SD) of 14. The mean time of evolution of the disease was 23 years (SD ±16). HLA-B27 was prevalent in 54 (69.2%). The sacroileitis was found in radiologic examination of 72 (92.2%), and 6 (7.7%) of them presented edema in magnetic resonance imaging. Other clinical traits were: 43 (55.1%) peripheric arthritis 43, 8 (10.3%) dactilitis, 33 (42.3%) enthesitis, 16 uveitis (20.5%), 2 (2.6%) inflammatory bowel disease and psoriasis 34 (43.3%). The following cardiovascular risk factors were registered: 25 (32%) smokers, 42 (53%) hypertension, 32 (41%) dislipemia, 9 (12%) diabetes, 9 (12%) hyperuricemia and 20 (20%) obesity. 14 patients had structural cardiopathy (11 ischemic cardiopathy and 3 aortic valvulopathy). The electrocardiographic register showed conductance disorders in 20 patients (25.6%). The details of these findings are specified in table 1.First grade auriculoventricular block5Second and third grade auriculoventricular block2Left anterior fascicular block1Right bundle branch block2Unspecific intraventricular conduction disorder4Bachmann interatrial conduction disorder1ConclusionsA quarter of our series of presented conduction disturbances in electrocardiography. The relation with disease evolution, as in Ankylosing Spondilitis remains yet to be analized.Disclosure of InterestNone declared
