Predisposing factors and uremic pericardial effusion among ESRD patients undergoing dialysis

Pericardial effusion and pericarditis are responsible for 3-5% of deaths due to tamponade, fatal arrhythmia and heart failure. Improvement in dialysis methods has allowed the initiation of the treatment at early stages. This study is designed to evaluate the prevalence of pericardial effusion and its predisposing factors among end-stage renal disease (ESRD) patients undergoing dialysis.

This is a cross-sectional study that included patients from the two Medical Centers in (XXX). These patients were presented with ESRD with a GFR <10 cc/min and were under long-term dialysis, also called chronic hemodialysis. The echocardiography was performed and patients with pericarditis and/or pericardial effusion due to non-uremic causes or dialysis were excluded.

Of 132 patients included, mild pericardial effusion was observed in 17(12.9%) patients, 8(6.1%) patients were presented with moderate and 1 (0.7%) had severe pericardial effusion. Among females, 9(15.8%) showed pericardial effusion whereas, it was reported in 8(10.7%) males, with no statistically significant difference. Furthermore, no significant difference was seen in the ages or etiologies of patients with or without pericardial effusion (50.5 ± 15.5 vs 52.8 ± 16.1, respectively).

Our study reports that echocardiography among dialysis patients is likely to determine the effectiveness of the dialysis procedure and can be a cost-effective approach. Futher studies regarding laboratory parameters are required in this area.
