Abstract 20522: Nonagenarians Have Significantly Higher In-Hospital Morbidity and Mortality Following Percutaneous Coronary Intervention When Compared to Non-Nonagenarians
Introduction: The number of very elderly patients undergoing percutaneous coronary intervention (PCI) is increasing, despite little data on in-hospital outcomes of nonagenarians after PCI. Whether age alone is an independent risk factor for complications remains uncertain, and the risk of intervention in this subset of patients in not known.
Hypothesis: Despite nonagenarians having fewer cardiovascular comorbidities, they have increased in-hospital mortality after PCI.
Methods: The Dartmouth Dynamic Registry was queried for all PCI’s between the years 2000 and 2015. Patients were subdivided into two groups based on their age (>89 and <90). Demographic features, procedural characteristics, and in-hospital outcomes were analyzed via standard descriptive statistics.
Results: Between 2000-2015, 17,375 patients > 90 years old and 182 nonagenarians underwent PCI. Nonagenarians had a lower incidence of smoking, hyperlipidemia, diabetes, but a higher incidence of chronic kidney disease (see Table 1). Nonagenarians were more likely to undergo left main and left anterior descending artery intervention. When compared to non-nonagenarians after PCI, nonagenarians had more than a three fold higher mortality and a higher incidence of hypotension requiring vasopressors (see Table 2).
Conclusion: Nonagenarians undergoing PCI remain rare. Despite nonagenarians having fewer cardiovascular comorbidities, they have higher in-hospital mortality and worse outcomes after PCI compared to non-nonagenarians.
