Clinical effectiveness of coronary stents in elderly persons: results from 262,700 Medicare patients in the American College of Cardiology-National Cardiovascular Data Registry.

ABSTRACT:

Objectives

The aim of this study was to compare outcomes in older individuals receiving drug-eluting stents (DES) and bare-metal stents (BMS).

Background

Comparative effectiveness of DES relative to BMS remains unclear.

Methods

Outcomes were evaluated in 262,700 patients from 650 National Cardiovascular Data Registry sites during 2004 to 2006 with procedural registry data linked to Medicare claims for follow-up. Outcomes including death, myocardial infarction (MI), revascularization, major bleeding, stroke, death or MI, death or MI or revascularization, and death or MI or stroke were compared with estimated cumulative incidence rates with inverse probability weighted estimators and Cox proportional hazards ratios.

Results

The DES were implanted in 217,675 patie
