AB0302 INTEREST OF THE SYSTEMATIC ELECTROCARDIOGRAM IN THE DETECTION OF CARDIAC INVOLVEMENT DURING SPONDYLOARTHROPATHIES AND RHEUMATOID ARTHRITIS

Background Cardiovascular risk is not uncommon in patients with chronic inflammatory rheumatism. Objectives The objective: To evaluate the interest of systematic electrocardiogram (ECG) as a tool for detecting cardiac abnormalities during spondyloarthropathies (SA) and rheumatoid arthritis (SA). Methods Consecutive patients suffering from SA, RA, hospitalized during the period from 2016 to 2017 and free from cardiovascular events were included. An ECG - 12-lead - was performed and interpreted by a cardiologist without the diagnosis. Results A total of 44 patients with SA were included (average duration 9 ± 8 years), 56 patients with RA (average duration 11 ± nine years). They were all asymptomatic on the cardiac level and without a cardiovascular history. The population was homogeneous, concerning the presence of the cardiovascular risk factors, except for the diabetes, more frequent in the RA groups. The proportions of extra systoles, atrioventricular blocks (2.2% in the SA group, 1.4% in the RA group), complete or incomplete left branch block (respectively: 0.7%, 0.6%), complete right limb block or left branch block (respectively: 0.8%, 2.7%) and abnormality suggestive of myocardial ischemia (5.2%, 10.8%) Conclusion In patients with no history of cardiovascular disease who are asymptomatic, performing a systematic ECG does not reveal the increased risk of specific cardiac complications related to these conditions in patients with SA and RA.
