SYNTAX score and the risk of stent thrombosis after percutaneous coronary intervention in patients with non‐ST‐segment elevation acute coronary syndromes: An ACUITY trial substudy
Bibliographic record
Abstract
OBJECTIVE: We sought to investigate the relationship between the SYNTAX score (SS) and stent thrombosis (ST) in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) undergoing percutaneous coronary intervention (PCI). BACKGROUND: The relationship between the SS and ST is undetermined. METHODS: We stratified 2,627 patients undergoing PCI in the ACUITY trial by SS tertile according to the current population (true tertiles, SS <7, SS = 7-12, and SS >12) and by the SYNTAX trial (original SYNTAX tertiles, SS <23, SS = 23-32, and SS >32). Thirty-day and 1-year rates of definite/probable ST were determined for each tertile. RESULTS: A total 30 (1.1%) and 41 (1.6%) definite/probable ST events occurred by 30 days and 1 year, respectively. When stratified by true tertiles, 30-day and 1-year rates of definite/probable ST were significantly greater in the highest tertile (SS >12; 2.0% and 2.8%) compared with the intermediate (SS = 7-12; 0.7% and 1.1%) and lowest tertiles (SS <7; 0.6% and 0.7%), P = 0.007 and P = 0.0009, respectively. When stratified by original SYNTAX tertiles, 30-day and 1-year rates of definite/probable ST were significantly greater in the highest (SS >32; 6.3% and 8.8%) and intermediate tertiles (SS = 23-32; 2.8% and 3.7%) compared with the lowest tertile (SS < 22; 0.8% and 1.2%), P <0.0001 for both. By multivariable analysis, the SS was an independent predictor for both 30-day and 1-year definite/probable ST. CONCLUSIONS: In patients with NSTE-ACS undergoing PCI, the extent and severity of CAD, as assessed by the SS before revascularization, was strongly associated with the occurrence of ST both at 30 days and 1 year. © 2014 Wiley Periodicals, Inc.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
