Percutaneous coronary interventions in nonagenarians: in-hospital mortality and outcome at one year follow-up.

Background: Limited information is available regarding outcome of very elderly patients referred for percutaneous coronary intervention (PCI).

Purpose: 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.

Conclusion: Hypotension and low ejection fraction correlated with in-hospital mortality and worst clinical outcome. Procedural success does not appear to decline in nonagenarians.
