Objectives: Disease activity has been considered as independent cardiovascular risk factor in rheumatoid arthritis (RA) patients. We aimed to evaluate the effect of RA disease activity on left ventricular (LV) and right ventricular (RV) functions by speckle tracking echocardiography (STE). Methods: 120 patients with RA without evidence of cardiovascular disease and 40 healthy control subjects were included. Disease activity was evaluated according to Simplified Disease Activity Index (SDAI) score and Disease Activity Score 28 (DAS28). LV and RV functions were assessed using conventional echocardiography and global longitudinal strain (GLS) technique measured by STE. Results: 81 patients had active disease while 39 patients were in remission. The LV and RV GLS value for active RA patients was reduced compared to RA patients in remission and control group (p = 7 and >2.8 respectively with sensitivity of 77.6%, specificity of 85.0% and area under ROC curve = 90.4 for SDAI score and with sensitivity of 89.7%, specificity of 71.7% and area under ROC curve = 89.4 for DAS28 score. Also, SDAI score and DAS28 were predictive for reduced RV GLS with a cut off value of >11 and >3 respectively with sensitivity of 73.1%, specificity of 93.5% and area under ROC curve = 91.6 for SDAI score and with sensitivity of 84.6%, specificity of 80.4% and area under ROC curve = 90.8 for DAS28 score. Conclusion: Disease activity in patients with rheumatoid arthritis is associated with lower left and right ventricular function. Disease activity scores can predict subclinical left and right ventricular dysfunction.
