Three years performance of Biodegradable Polymer Sirolimus Eluting Stent in all comer patients undergoing Percutaneous Coronary Intervention.
Bibliographic record
Abstract
Introduction: Contemporary evidence suggest the comparable performance of biodegradable polymer sirolimus eluting stents (BPSES) with that of second generation durable polymer drug eluting stents. This study was done to evaluate the performance of BPSES in all comer patients undergoing percutaneous intervention (PCI) in real world setting over a period of three years. Materials & Methods: This was a prospective observational study, wherein all comer consecutive patients undergoing PCI with BPSES (Yukon Choice Elite stent by Translumina Therapeutics, India) were enrolled and followed up for 3 years. The study's primary endpoint was the Device Oriented Composite Endpoint (DOCE), which included cardiac death, target vessel myocardial infarction (MI), and clinically driven target lesion revascularization (TLR); the co-primary endpoint was the Patient-Oriented Composite Endpoint (POCE), which included all-cause mortality, any MI , and any repeat revascularization and the secondary endpoint was definite or probable stent thrombosis (DST & PST). Results: 301 patients with 502 lesions were treated with 485 BP-SES. Mean age of the study cohort was 61.6± 9.3 yrs and males were 79.1%. 18.6% patients were diabetic, 29.6% had ejection fraction less than 40% and 73.1% patients presented with acute coronary syndrome (ACS). Majority of the patient had triple vessel disease (TVD) (51.8%), multivessel PCI was done in 15.6% and complex PCI in 26.2% patients. A mean of 1.6 ±0.8 stents per patient with mean diameter 3.0 ± 0.3 mm and mean length of 27.2 ± 0.8 mm were placed. DOCE & POCE occurred in 7.9% (cardiac death-4.8%, TLR-2.6% & target vessel MI-0.4%) and 12.8% (All deaths-9.7%, any MI- 0.4% and any revascularisation-2.6%) patients respectively at three years follow-up. DST & PST rate was 0.9% and 0.4% respectively in the study cohort. All the cases of stent thrombosis occurred within 30 days. Kaplan Meier analysis revealed that diabetes mellitus, low ejection fraction (EF), acute coronary syndrome (ACS), long stents and complex intervention had no impact on occurrence of DOCE & POCE while using BP-SES in all-comer patient population. Conclusion: Present study showed favourable long term safety and efficacy profile of BP-SES for all-comer patients undergoing PCI.

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.
