Patterns of stress testing and diagnostic catheterization after coronary stenting in 250 350 medicare beneficiaries.

ABSTRACT:

Background

Patterns of noninvasive stress test (ST) and invasive coronary angiography (CA) utilization after percutaneous coronary intervention (PCI) are not well described in older populations.

Methods and results

We linked National Cardiovascular Data Registry CathPCI Registry data with longitudinal Medicare claims data for 250 350 patients undergoing PCI from 2005 to 2007 and described subsequent testing and outcomes. Between 60 days post-PCI and end of follow-up (median 24 months), 49% (n=122 894) received ST first, 10% (n=25 512) underwent invasive CA first, and 41% (n=101 944) had no testing. Several clinical risk factors at time of index PCI were associated with decreased likelihood of downstream testing (ST or CA, P<0.05 for all), including older age (hazard ratio [H
