OBJECTIVES: To describe decade- long trends (1999-2009) in the rates of not undergoing cardiac catheterization and percutaneous coronary intervention (PCI) in individuals aged 65 and older presenting with an ST-segment elevation acute myocardial infarction (STEMI) and factors associated with not undergoing these procedures.
DESIGN: Observational population-based study.
SETTING: Worcester, Massachusetts, metropolitan area.
PARTICIPANTS: Individuals aged 65 and older hospitalized for an STEMI in six biennial periods between 1999 and 2009 at 11 central Massachusetts medical centers (N=960).
MEASUREMENTS: Analyses were conducted to examine the characteristics of people who did not undergo cardiac catheterization overall and stratified into two age strata (65-74, > /=75).
RESULTS: Between 1999 and 2009, dramatic declines (from 59.4% to 7.5%) were observed in the proportion of older adults who did not undergo cardiac catheterization at all greater Worcester hospitals. These declines were observed in individuals aged 65 to 74 (58.4-6.7%) and in those aged 75 and older (69.4-13.5%). The proportion of individuals not undergoing PCI after undergoing cardiac catheterization decreased from 36.6% in 1999 to 6.5% in 2009. Women, individuals with a prior MI, those with do-not-resuscitate orders, and those with various comorbidities were less likely to have undergone these procedures than comparison groups.
CONCLUSION: Older adults who develop an STEMI are increasingly likely to undergo cardiac catheterization and PCI, but several high-risk groups remain less likely to undergo these procedures.
