Abstract
Feasibility and efficacy of complex percutaneous coronary intervention (PCI) in the elderly, a more frail population due to more comorbidities is incompletely understood. We therefore set out to compare success and complication rate of PCI for chronic total occlusion (CTO) in octogenarians, in comparison to non-octogenarians. Data from 267 patients (58 patients over 80 years of age and 209 under 80 years of age) who had undergone CTO PCI were analyzed. To compare the results we calculated the propensity score and used inverse probability of treatment weighting. We evaluated demographic, clinical, angiographic, and periprocedural information. The median age of the total collective was 68 (31–90) years (octogenarian collective 82 (80–90) years vs non-octogenarians 65 (31–79) years). We observed a high success rate in both collectives (82.8% vs 90.4%, p = 0.10) and no difference in periprocedural complications or complications in the follow-up period. In our collective restenosis rate at follow-up was comparable to the propensity sore weighted population (11.3% vs 16.3%, p = 0.9). Our results show that CTO PCI in older patients is safe and feasible with comparable in-hospital and follow-up complication rates compared to a younger patient population.
