Comparison of Safety after Percutaneous Coronary Intervention Between Octogenarians and Counterparts with Coronary Artery Disease

Background: Elderly patients usually have comorbid and poor general conditions. They are more likely to have complex coronary lesions with cardiac dysfunction. Percutaneous coronary intervention (PCI) in octogenarians remains controversial. In this study, we determined the safety after PCI for octogenarians and their younger counterparts with coronary artery disease. Methods: We reviewed 1,057 patients (110 octogenarians vs. 947 younger counterparts) who underwent PCI for coronary artery disease at Saint Carollo Hospital. We analyzed the baseline characteristics, angiographic findings, in hospital mortality, and post procedural complications between the two groups. Results: The mean ages of octogenarians and younger counterparts were 83.1±4.5 years and 62.6±10.3 years, respectively. The octogenarian group had a significantly (p
