Evaluation of early cardiac dysfunction in patients with systemic lupus erythematosus with or without anticardiolipin antibodies

The aim of this study was to use transthoracic Doppler echocardiographic (TTE) imaging methods to identify cardiac dysfunction, an indicator of subclinical atherosclerosis in asymptomatic systemic lupus erythematosus (SLE) patients in terms of cardiac effects. This study involved 80 patients: a study group (n = 50) and control group (n = 30). They were categorized into four subgroups: anticardiolipin antibodies (aCL) (+) (n = 14) and aCL (−) (n = 36); systemic lupus erythematosus disease activity index (SLEDAI) ≥ 6 (n = 15) and SLEDAI < 6 (n = 35); disease period ≥ 5 years (n = 21) and disease period < 5 years (n = 29); major organ involvement (+) (n = 19), major organ involvement (−) (n = 31). The ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (E/E′) for the study group was found to be higher than the control (p < 0.01). Systolic septal motion velocity (Ssm) was lower in the study group compared with the control (p < 0.01). Left atrium (LA) dimension was greater...
