Abstract

Objectives We evaluated cardiac function in juvenile idiopathic arthritis (JIA) patients by 2D speckle-tracking echocardiography (2DSTE) and to assess possible associations with clinical, laboratorial, and treatment data. Methods A group of 42 JIA patients and 42 healthy controls were evaluated using both conventional echocardiography and 2DSTE. JIA patients underwent clinical and laboratory assessment. Results Conventional echocardiography data demonstrated normal left ventricular (LV) ejection fraction in both groups (71 vs. 71%; p = .69). 2DSTE analysis demonstrated that JIA patients presented significantly lower LV global systolic longitudinal strain (LVGLS) (-18.76 vs. -22%; p < .0001), LV systolic strain rate (LVSSR) (1.06 vs. 1.32 s(-1); p < .0001), LV diastolic strain rate (LVDSR) (1.58 vs. 1.8 s(-1); p < .0137), right ventricular global systolic strain (RVGLS) (-24.1% vs. -27.7%; p = .0002), and right ventricular systolic strain rate (RVSSR) (1.4 vs. 1.8 s(-1); p = .0035). JIA patients under biological agents presented higher LVGLS (p = .02) and RVLS (p = .01). We also detected an association between LVGLS and C-reactive protein [CRP; -20% in normal CRP (10/42) vs. -18% in elevated CRP patients (32/42), p = .03]. Conclusions JIA patients present different echocardiographic status from healthy patients. Moreover, our data suggest that JIA patients under biological agents present association with better cardiac function as shown by strain analysis. (AU)
