title: Percutaneous coronary revascularization in elderly patients: impact on functional status and quality of life.
abstract: BACKGROUND
  Percutaneous coronary intervention (PCI) is frequently performed in elderly patients, but little is known about its impact on overall health and quality of life.
  
  
  OBJECTIVE
  To examine changes in health-related quality of life among elderly patients after PCI.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  75 U.S. hospitals.
  
  
  METHODS
  Participants in two clinical trials of PCI.
  
  
  METHODS
  Health-related quality of life was assessed by using the Medical Outcomes Study Short Form (SF-36) survey and the Seattle Angina Questionnaire at baseline, 6 months, and 1 year.
  
  
  RESULTS
  Serial data on health-related quality of life were available for 295 elderly (> or =70 years) and 1150 nonelderly (<70 years) patients. At 6 months, physical health had improved in 51% of elderly patients and mental health had improved in 29%. Cardiovascular-specific health status had improved in 58% to 75% of elderly patients. Improvement did not significantly differ between elderly and non-elderly patients at 6 months or 1 year.
  
  
  CONCLUSIONS
  Elderly patients selected for participation in a trial of PCI had substantial improvements in health-related quality of life after PCI that were similar to those in younger patients.
