• W2895542578 abstract "Background Valvular heart disease (VHD) is one of the commonest cardiovascular manifestations of autoimmune disease, including systemic lupus erythematosus1. Its prevalence ranges from 18% to 74%, with predominantly regurgitant lesions and valvular thickening. The cause of such abnormalities is yet unclear. There have been very few such studies performed in Asian patients, and only one in Malaysian patients to date. Objectives We sought to evaluate the valvular abnormalities of a multiracial cohort of lupus patients and also examine the association of these abnormalities with potentially related factors. Methods The medical records of all patients with SLE who had attended the Rheumatology Clinic of Kuala Lumpur Hospital between January 2008 and December 2016 were reviewed. All patients fulfilled the 1997 updated ACR criteria for SLE. Transthoracic echocardiographic examinations as part of their standard of care were performed by trained technicians using a standardised protocol. Multivariable logistic regressions were conducted to determine factors associated with valvular abnormalities in these patients. Results There were 207 patients in this study. VHD was found in 67.1% of patients: theywere asymptomatic and did not have murmurs. The main abnormalities were tricuspid regurgitation (TR) (45.4%), mitral regurgitation (MR) (40.6%) and valvular thickening (19.2%). The majority of cases comprised mild TR (37.2%), mild MR (25.1%) and mitral valve thickening (10.6%). There were more patients with moderate to severe MR compared to TR (15.5% vs 8.2%). Median pulmonary artery systolic pressure was 23.0 mmHg (IQR 13.2). Risk of VHD was higher in patients with lower C3 levels ( Conclusions More than half of our patients had VHD, with regurgitant lesions and valvular thickening being the commonest abnormalities. Our finding of the association of MR and mitral valve thickening with APS and individual antiphospholipid autoantibodies concurs with earlier studies. However, what were unusual about our cohort were that TR was the prevalent abnormality and the association of VHD with low C3. We suggest that all patients with SLE have at least one echocardiogram, especially the patients with APS or antiphospholipid antibodies.
