Temporal trends in percutaneous coronary intervention outcomes among older patients in the United States.

ABSTRACT:

Background

New percutaneous coronary intervention (PCI) device technologies are often rapidly adopted into clinical practice, yet few studies have examined the overall impact of these new technologies on patient outcomes in community practice.

Methods

In hopes of determining temporal trends in PCI outcomes, we used data from the Centers for Medicare & Medicaid Service's Chronic Condition Warehouse (n = 3,250,836) by comparing patient characteristics and rates of 3-year major adverse cardiac events (MACE) across the balloon angioplasty (POBA) era (01/1991-09/1995), the bare metal stent (BMS) era (02/1998-04/2003), and the drug-eluting stent (DES) era (05/2004-10/2006). The adjusted association between era and outcomes was determined with Cox proportional hazards modeling (POB
