Descrizione dettagliata
BACKGROUND. Newer-generation drug-eluting stents (DES) remain associated with late stent-related adverse events at approximately 2% per year, driven by neoatherosclerosis, delayed endothelial healing, and chronic inflammation attributable to permanent polymer coatings. Polymer-free DES were developed to remove this substrate. The ABLUMINUS NP (Concept Medical, Tampa, FL, USA) is a novel polymer-free sirolimus-eluting stent built on a thin-strut (73 micrometres) cobalt-chromium platform, with drug delivery via biodegradable phospholipid submicron carriers (200-300 nm) confined to the abluminal surface, and a proprietary fusion coating extending sirolimus up to 5 mm beyond the stent edges. The device received CE marking on 24 January 2020. Only limited non-randomized Indian clinical data exist; no Western clinical data have been published.
OBJECTIVES. Primary: to evaluate device-oriented safety and efficacy (TLF at 12 months) of the ABLUMINUS NP stent in an all-comer population undergoing PCI at Geneva University Hospitals. Secondary: TLF at 2 and 5 years; individual components of TLF (cardiac death, target vessel MI, clinically indicated target lesion revascularisation) at 30 days, 12 months, 2 years, and 5 years; patient-oriented composite endpoint (all-cause death, any MI, any revascularisation); stent thrombosis (definite / probable, ARC-2, with temporal classification); target vessel failure; major bleeding (BARC 3 or 5); all-cause mortality; and late lumen loss when angiographic follow-up is available.
DESIGN. Prospective, single-centre, single-arm observational registry (Category A research with human subjects per the Swiss Human Research Act). Hybrid enrolment: retrospective identification from January 2021, prospective consent, and prospective follow-up at 30 days, 12 months, 2 years, and 5 years via medical records and telephone interview.
POPULATION. All consecutive adult patients (>= 18 years) treated with at least one ABLUMINUS NP stent at Geneva University Hospitals between January 2021 and December 2025, with an indication for PCI according to current European or American guidelines, able to provide written informed consent, and with sufficient knowledge of French, German, English, or Italian. Anticipated enrolment approximately 50 patients.
STATISTICS. Exploratory, descriptive analysis. Binary endpoints with Clopper-Pearson 95% confidence intervals; time-to-event analysis by Kaplan-Meier with Greenwood 95% CIs. Pre-specified exploratory subgroup analyses (sex, clinical presentation, diabetes, age, lesion complexity, stent length) presented as forest plots without between-group p-values. Sensitivity analyses include per-protocol, complete-case, landmark (30 days to 12 months), Fine-Gray competing-risk, and tipping point analyses. Analyses in Python (lifelines, pandas, scipy, statsmodels). Reporting follows STROBE.
