Abstract |
Background: Because of co-morbidities; shorter life expectancy; higher risk for
complications; and poor clinical outcomes of percutaneous coronary intervention (PCI); the
treatment strategy for the elderly is often conservative. The aim of this study was to evaluate
long-term clinical outcomes of elective PCI in selected elderly patients with coronary artery
disease and compare with young patients in real world scenario. Methods The present study enrolled 1895 consecutive patients who underwent elective PCI
from March 2003 to October 2007. The definition of elderly patient in this study was ≥ 75 yearold.
Selected elderly patients (198 patients) who had more than 70 in Karnofsky score underwent
elective PCI during study period. The outcomes of elderly group were compared to those of
younger group (1697 patients) in the same period. The primary outcome is a composite of major
adverse cardiac events (MACE) including cardiac death; myocardial infarction; and target vessel
revascularization; 3 years after the index procedure. Results The elderly group (77.9 ± 2.8 year-old) had more female gender (52.0% vs. 33.2%; p
< 0.01); lesser smoker (19.7% vs. 37.2%; p < 0.01); and more acute coronary syndrome (67.9%
vs. 59.4%; P = 0.04); than the young group (60.3 ± 9.3 year-old). However; there was no
significant difference in MACE (6.5% in elderly vs. 7.1% in younger group; p = 0.81) 3 years
after index procedure. Conclusions Three-year clinical outcomes of elective PCI in selected elderly patients were
acceptable; comparable to those of young patients. |
