title: An audit of cardiac pacing in the elderly: effect of myocardial infarction on outcome.
abstract: OBJECTIVE
  To audit the outcome of temporary endocardial pacing in an elderly population.
  
  
  METHODS
  Retrospective case-series analysis.
  
  
  METHODS
  The Department of Medicine for the Elderly at the Wrexham Maelor Hospital, a District General Hospital with 612 beds serving a catchment population of 220,000.
  
  
  METHODS
  A sample of 50 consecutive elderly patients, with an age range of 65 to 99 years, undergoing transvenous cardiac pacing.
  
  
  METHODS
  Length of stay in hospital, complications of the pacing procedure, whether a permanent pacemaker was installed, and whether the patient died within 1 month of admission.
  
  
  RESULTS
  There was no difference in length of stay between those with a myocardial infarction and those without. Minor complications occurred in three patients (one local infection and two "failures to pace"). Major complications occurred in two patients (septicemia and pneumonia). More patients without a myocardial infarction (86.9%) went on to implantation of a permanent pacemaker than those with an infarction (11.1%, P = 0.001), and fewer of them died (8.7% compared with 48.1%, P = 0.0025). In those patients with a myocardial infarction who died, there was no difference between the proportions who had inferior (7/18) and anterior (5/9) infarctions.
  
  
  CONCLUSIONS
  Cardiac pacing seems to be a safe and reliable procedure in the elderly, although long term morbidity and mortality may be dependent on the presence or absence of myocardial ischaemic disease. Myocardial infarction in the elderly is an event of major significance, carrying with it a high mortality rate, particularly if accompanied by cardiogenic shock and the need for cardiac pacing.
