Our goal was to assess the patient profile, feasibility of coronary angiography (CAG), effectiveness (successful relieving of the coronary artery\u2019s narrowing or occlusion) of percutaneous coronary intervention (PCI) and safety (mortality and other complications) of both procedures in nonagenarians. Methods: The database of the Dr. E. Warmi\u0144ski Clinical Hospital of the Bydgoszcz University of Technology was searched for patients aged 90 years and older who underwent CAG and PCI between 2013 and 2023. We retrospectively analysed the case reports of these patients, including reason for hospital admission, course of hospitalisation, procedure data, and complications. Results: A total of 150 nonagenarians meeting the criteria were found, with a mean age of 92 years and 63% being female. A total of 110 patients (73%) were admitted on the basis of acute coronary syndrome (ACS). Upon CAG, 108 patients had obstructive coronary artery disease confirmed, 90% of whom had multivessel disease. In 96 out of 108 of these patients (that is, 89%), PCI was performed successfully in 89 (93%) procedures. Transradial access was used in 112 patients (75%). According to the diagnosis, PCI was performed in all cases (100%) of STEMI patients, in 80% cases of non-ST elevation acute coronary syndrome (NSTE-ACS) patients, and in 27% cases of stable CAD patients. Median time of hospitalisation was 6.5 days (IQR 4\u201310). In the course of hospitalisation, mortality was 8.7% (13 out of 150), although two cases were non-cardiological in nature. In the PCI group, mortality was 11.5% (11 out of 96); all 11 were treated due to ACS (no deaths in patients with stable ACS). In the STEMI subgroup, mortality was much higher at 33% (4 out of 12, with all 4 admitted with cardiogenic shock). Accordingly, in the NSTEMI group, mortality was 8.97%. Other complications in the PCI group were perforation of coronary artery in 1 case, access site complications in the case of transfemoral access in 10 patients, bleeding requiring transfusion in 2 patients, and contrast-induced nephropathy (CIN) in 4 patients. Conclusions: This analysis demonstrates that the CAG and PCI procedures are feasible and effective in nonagenarians, and the risk of complications is not as great as it was heretofore believed.<\/jats:p>","DOI":"10.3390\/jcm14207371","type":"journal-article","created":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:27:29Z","timestamp":1760963249000},"page":"7371","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Percutaneous Coronary Interventions in Nonagenarians: Single-Centre Insights"],"prefix":"10.3390","volume":"14","author":[{"given":"Gwidon","family":"Polak","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Bydgoszcz University of Science and Technology, Aleje Prof. S.
