title: Pericardial effusion as a cause of morbidity in patients on maintenance hemodialysis: is it preventable?
abstract: OBJECTIVE
  Cardiovascular diseases are the cause for 45% mortality and 20% morbidity in hemodialysis (HD) patients. Pericardial effusion (PE) accounts for 03-04% of all deaths in HD patients as a result of tamponade, arrhythmias or heart failure. This study aims to find out the prevailance and precipitating factors for PE in hemodialysis patients.
  
  
  METHODS
  Fifty-five patients were identified for echo-cardiographic assessment on the basis of signs and symptoms suggestive of PE i.e., hypotension during dialysis, dyspnea, globular heart in chest x-ray, raised JVP, soft heart sounds and low voltage ECG. A matched controlled group of 55 patients for age, sex, dialysis schedule, cause of ESRD and dialysis bath, was also studied echocardiographically.
  
  
  RESULTS
  Pericardial Effusion was detected in 12 patients (10.9%), 10 (83.3%) were on 2/week and only two on 3/week dialysis. Of these 75% were non-compliant in fluid intake and 58.3% were irregular in treatment. The morbidity of PE in study group (18.2%) is significantly higher as compared to controls (3.6%) (P = < 0.05). No correlation was found between development of PE and high iPTH and low albumin levels. Ten patients with mild PE responded to vigorous dialysis. Two patients developed cardiac tamponade needing pericardiocentesis.
  
  
  CONCLUSIONS
  We have identified 2/week dialysis (inadequate dialysis dose), acetate bath and fluid and dialysis non-compliance as factors contributing to development of PE in HD patients.
