Ten-Year Clinical Outcomes From a Trial of Three Limus-Eluting Stents With Different Polymer Coatings in Patients With Coronary Artery Disease
Bibliographic record
Abstract
BACKGROUND: New-generation drug-eluting stents offer the potential for enhanced late outcomes in comparison with early generation drug-eluting stents. However, assessment of extended long-term outcomes for these devices is lacking, especially regarding the comparison between new-generation drug-eluting stents with biodegradable or permanent polymers. The aim of this study is to compare the efficacy and safety of biodegradable polymer-based sirolimus-eluting stents (BP-SES; Yukon Choice PC) versus permanent polymer-based everolimus-eluting stents (PP-EES; Xience) versus early generation permanent polymer-based sirolimus-eluting stents (PP-SES; Cypher) at 10-year follow-up. METHODS: Overall, 2603 patients were randomized to treatment with BP-SES (n=1299), PP-EES (n=652), or PP-SES (n=652). The primary end point of this analysis was major adverse cardiac event, the composite of death, myocardial infarction, or target lesion revascularization. The main secondary end point of interest was definite/probable stent thrombosis. Follow-up at 10 years was available in 83% of the study patients. RESULTS: The 10-year incidence of major adverse cardiac event (BP-SES 47.7% versus PP-EES 46.0% versus PP-SES 54.9%, P=0.003) and mortality (BP-SES 31.8% versus PP-EES 30.3% versus PP-SES 37.2%, P=0.02) was different among the groups. Definite/probable stent thrombosis was not significantly different among the groups (BP-SES 1.8% versus PP-EES 2.5% versus PP-SES 3.7%, P=0.09). Definite stent thrombosis was significantly different among the groups (BP-SES 1.1% versus PP-EES 0.8% versus PP-SES 2.4%, P=0.03). There were no significant differences between BP-SES and PP-EES. CONCLUSIONS: In this unique long-term outcome analysis, BP-SES and PP-EES showed comparable clinical outcomes out to 10 years. PP-SES had higher rates of major adverse cardiac events and definite stent thrombosis. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov . Unique identifier: NCT00598676.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
