Atrial ejection force in systemic autoimmune diseases.
Systemic autoimmune disorders may affect several organs, including the heart. We analyzed two-dimensional and pulsed Doppler echocardiograms of patients (n = 37) with systemic lupus erythematosus (SLE, n = 24) or rheumatoid arthritis (RA, n = 13) to determine whether atrial ejection force (AEF) could represent a suitable parameter for detecting left ventricular filling abnormalities in SLE and RA. In both patient subgroups, AEF was significantly higher than in healthy controls (n = 40) matched for gender and age (14.0 +/- 5.4 vs. 11.0 +/- 3.5 kdyn, p < 0.01). Because conventional echocardiographic parameters of left ventricular function failed to detect such a difference, AEF might serve as an additional sensitive parameter for detecting left ventricular diastolic filling abnormalities early in the course of a systemic autoimmune disease.
