title: [Pericardial effusion in the elderly: A different disease?].
abstract: OBJECTIVE
  The aim of the present study was to assess possible differences in etiologic spectrum and clinical course of pericardial effusion in elderly patients, as has been previously suggested, and therefore determine whether clinical, management should be based on patient age.
  
  
  METHODS
  All echocardiograms performed in our hospital from 1990 to 1996 were screened for pericardial effusion, and those with moderate or large effusions were selected. Patients under 66 years of age were included in group I, and those above 65 years were assigned to group II.
  
  
  RESULTS
  We selected 322 patients with moderate (122) or with large (200) effusions. 221 patients being included in group I (aged 15-65, mean 47) and 101 in group II (aged 66-88, mean 72.5). Effusion was large in 60% of group I and in 66% of group II (p = NS), and tamponade occurred in 36% and 38.6%, respectively (p = NS). Specific pericardial infections (tuberculous and purulent pericarditis) were more frequent in group I (5.9 versus 0.9%; p < 0.05). No significant differences were found in incidence of idiopathic (33 vs 38%) or neoplastic (14.4 vs 10.8%) etiologies. During follow-up (96% of the patients, median time of 11 months, range 1-58 months) the mortality (24 vs 30%) and evolution to cardiac constriction (4 vs 2%) were similar in the two groups, but persistence of effusion was more common in group II (6.3 vs 14%; p < 0.05).
  
  
  CONCLUSIONS
  Our study suggests that etiology, clinical course and prognosis of moderate and large pericardial effusion are, in general, similar in elderly and younger patients. Thus, management should be similar in the different age groups, and no etiologic form of pericardial disease should be ruled out because of patient's age when considering the differential diagnosis.
