Aim: As a result of a higher prevalence of comorbidities, elderly adults are often underrepresented in clinical trials, and more often experience complications during percutaneous coronary intervention. Our aim was to evaluate clinical outcomes of patients older than 80 years, compared with their younger counterparts, when bioresorbable polymer biolimus A9 drug-eluting stent is used for their treatment. Methods: The prospective, observational e-Nobori registry was created to validate the safety and efficacy of bioresorbable polymer drug-eluting stent in unselected patients. The primary end-point of the study was freedom from target lesion failure defined as a composite of cardiac death, target vessel-related myocardial infarction and clinically-driven target lesion revascularization at 1 year. Results: There were 781 (7.8%) octogenarians, they were less frequently male (62% vs 77%; P < 0.0001) and more often presented as acute coronary syndrome (44% vs 39%; P = 0.0182). The index percutaneous coronary intervention success was lower in the elderly patients (98% vs 99%; P = 0.0398). One-year follow up was completed for 97% of the elderly patients and 99% of the younger patients. The difference in target lesion failure (3.33% vs 2.83%; log–rank P = 0.0114) was mainly driven by increased mortality in octogenarians (3.73% vs 1.47%; P < 0.0001). Elderly patients had more bleeding and vascular complications (2.67% vs 1.05%; P = 0.0001). Conclusions: Despite advanced age, multiple comorbidities and complexity of treated lesions, clinical outcomes are favorable in octogenarians treated by bioresorbable polymer biolimus A9 drug-eluting stent.
