Percutaneous Coronary Intervention in the Very Elderly: In Hospital Clinical Outcomes: Experience from a Single Private Institution

Abstract

Objective: To assess the in-hospital clinical outcome following percutaneous coronary intervention (PCI) in very elderly patients (VEP), aged≥85 years, compared to a control group (CG) of patients <85 years. Between November 2004 and January 2007, 1699 consecutive PCI procedures were evaluated, 102 (6%) PCI procedures were performed in VEP and 1597 (94%) in patients <85 years. Results: The mean age in the VEP group was 87.4± 2.4 years vs. 66.7± 11.2 years in the CG (p< 0.0001). There were more females in the VEP group 49% vs. 22% in the CG p< 0.0001. Acute coronary syndromes (ACS) were a more frequent indication for PCI in VEP than in the CG: ST elevation myocardial infarction (STEMI) 14.7% vs. 8.3% p= 0.025 and non-STEMI ACS 54.9% vs. 43.5% p= 0.024. The proportion of drug-eluting stents used was lower in VEP than in the CG (86.5% vs. 92.9% p= 0.005). Angiographic success rates were similar in both groups (95.9%). Global in-hospital mortality was higher in the V p d b t g V A C a o d
