title: Same-day discharge is feasible and safe in the majority of elderly patients undergoing elective percutaneous coronary intervention.
abstract: BACKGROUND
  Same-day discharge after elective percutaneous coronary intervention (PCI) is safe in the majority of patients. However, the elderly have more comorbidities and less favorable coronary and peripheral arterial anatomy, which may preclude safe same-day discharge after PCI. We assessed the feasibility and safety of same-day discharge in an elderly cohort of patients.
  
  
  METHODS
  A total of 1,580 consecutive patients undergoing elective PCI in a single center between January 2001 and January 2009 were included in the study. We compared the outcomes of elderly patients aged 75 or older to control patients under the age of 75 years. Patients were examined 6 hours post procedure and discharged if there were no complications.
  
  
  RESULTS
  Of the 1,580 study patients 212 (13.4%) were elderly and 1,365 (86.6%) were younger controls. The elderly were more likely to be female, hypertensive and to have had previous coronary artery bypass graft (CABG) surgery and less likely to be smokers or to have hyperlipidemia (all p < 0.05). The number of lesions treated and their complexity were similar in both groups. Procedural success, in-hospital major adverse cardiac events (MACE) and the rates of same-day discharge were also similar in both groups. Same-day discharge was achieved in the majority (84%) of the elderly. There were no deaths within 24 hours of discharge. Readmission within 24 hours of discharge was rare (< 0.7%) in both groups. The 30-day MACE rate was low in both the elderly (3.3%) and control groups (3.6%; p = 1.0).
  
  
  CONCLUSIONS
  Same-day discharge is safe and feasible in the majority of elderly patients following elective PCI.
