title: Percutaneous coronary interventions in nonagenarians: in-hospital mortality and outcome at one year follow-up.
abstract: BACKGROUND
  Limited information is available regarding outcome of very elderly patients referred for percutaneous coronary intervention (PCI).
  
  
  OBJECTIVE
  This study aimed to assess acute and intermediate term clinical outcomes among nonagenarians.
  
  
  METHODS
  The study included 32 consecutive nonagenarian patients undergoing PCI between January 2001 to August 2006. There were 6 (19%) patients admitted with acute ST-segment elevation myocardial infarction (STEMI), 10 (31%) patients with non-STEMI, and 16 (50%) patients with unstable angina pectoris. Receiver-operator characteristic curve (ROC) analysis was done to define the relationship between heart rate, blood pressure, left ventricle ejection fraction, serum creatinine level, and mortality.
  
  
  RESULTS
  Results: Immediate procedure success was achieved in 28 (88%) patients. Cumulative mortality at hospital discharge was 3(9%), at 6 months it was 6 (19%) and remained 6(19%) at 1 year follow-up.
  
  
  CONCLUSIONS
  Hypotension and low ejection fraction correlated with in-hospital mortality and worst clinical outcome. Procedural success does not appear to decline in nonagenarians.
