There are limited contemporary data available describing the characteristics of patients who neither died nor were readmitted to the hospital during the first year after hospital discharge for an acute myocardial infarction (AMI) in comparison with those who died and/or were readmitted to the hospital during this high-risk period. Residents of the Worcester, Massachusetts, metropolitan area discharged after an AMI from 3 central Massachusetts hospitals on a biennial basis from 2001 to 2011 comprised the study population. The average age of this population (n = 4,268) was 69 years, 62% were men, and 92% were white. From 2001 to 2011, 43.5% of patients were classified as low-risk survivors of an AMI, 12.3% died, and 44.2% did not die but had at least 1 rehospitalization during the subsequent year. The proportion of low-risk survivors increased from 42.6% to 46.4%, whereas the proportion of those who died within a year after hospital discharge decreased from 14.3% to 10.5%, respectively, during the years under study. After adjusting for several patient characteristics, younger (≤65 years) persons, men, those who were married, those who did not present with multimorbidities, and patients who did not develop in-hospital clinical complications were more likely to be classified as a low-risk AMI survivor. Identifying low-risk survivors of an AMI may help health care providers to focus more intensive efforts and interventions on those at higher risk for dying and/or being readmitted to the hospital during the postdischarge transition period after an AMI.

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.
