Background: Nonagenarian patients who undergo percutaneous coronary intervention (PCI) are increasing, and a few previous studies have reported their long-term outcomes. However, differences in their long-term outcomes between generations remain unclear. This study aimed to investigate 1-year all-cause and cardiovascular (CV) mortality, and major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, and stroke) of nonagenarian patients who underwent PCI compared with the other elder patients, using a nationwide registration system. Methods: The patient-level data registered between January 2017 and December 2017 was extracted from the J-PCI OUTCOME Registry endorsed by the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT). The one-year all-cause and cardiovascular (CV) mortality, MACE, and major bleeding events were identified. Results: Out of 40,722 patients over 60 years of age, 880 (2.1%) were nonagenarians. For nonagenarians, the 1-year mortality rate was substantial (13.5%). The MACE and CV death rates were also high (8.1%, and 6.8%, respectively) for nonagenarians, and these event rates were approximately 1.5 times higher in nonagenarians than octogenarians. Multivariate regression analysis showed that presentation with cardiogenic shock [hazard ratio (HR) 2.32; 95 confidence intervals (CI): 1.22–4.41], or cardiac arrest (HR 2.91; 90% CI: 1.28–6.62), and use of oral anticoagulants (HR 2.10; 90% CI: 1.07–4.12) were the predictors of 1-year MACE. Conclusions: Even in the contemporary era, nonagenarians who have undergone PCI still face a considerably increased risk for adverse cardiovascular events that reduces long-term survival. In addition to having poorer lesion characteristics, adverse events, including death, MACEs, and major bleeding, occurred 1.5 times more frequently in nonagenarians than in octogenarians.
