Abstract

Several randomized trials have demonstrated the benefits of an invasive strategy for older patients with acute coronary syndromes (ACS); however, there are limited real-world data of the temporal trends in the use of percutaneous coronary intervention (PCI) in this population. This was a retrospective observational analysis. We queried the National Inpatient Sample database from 1998 to 2013 for patients aged ≥70 years who had non-ST-elevation acute coronary syndrome (NSTE-ACS) or ST-elevation myocardial infarction (STEMI). We reported the temporal trends of PCI and in-hospital mortality. A total of 6,720,281 hospitalizations with ACS were identified in advanced age patients, 18.3% of whom also underwent PCI. There was an upward trend in the rate of PCI in older adults ≥70 years with any ACS from 9.4% in 1998 to 28.3% in 2013 (p < 0.001), as well as in cases of PCI for NSTE-ACS (7.3% in 1998 vs 24.9% in 2013, p < 0.001) and PCI for STEMI (11% in 1998 vs 35.7% in 2013, p = 0.002). This upward trend was consistent in all age categories (70 to 79), (80 to 89) and ≥90 years. Despite an increase in the prevalence of comorbidities for ACS hospitalizations aged ≥70 years who received PCI, the in-hospital mortality rate showed a downward trend (p < 0.001). Multivariate analysis adjusting for various comorbidities showed that PCI was associated with lower in-hospital mortality and length of hospital stay among elderly with NSTE-ACS and STEMI. In conclusion, in this 16-year analysis there was an increase in the rate of PCI procedures among older adults with ACS. PCI was independently associated with lower mortality in elderly patients with ACS.
