Abstract
AIM: We sought to examine the short- and long-term outcomes of patients who developed contrast-induced acute kidney injury (CI-AKI; defined as an increase in serum creatinine of ≥0.5 mg/dL or a 25% relative rise within 48 h after contrast exposure) from the large-scale HORIZONS-AMI trial. METHODS AND RESULTS: Multivariable analyses were used to identify predictors of CI-AKI, as well predictors of the primary and secondary endpoints. The incidence of CI-AKI in this cohort of ST-segment elevation myocardial infarction (STEMI) patients was 16.1% (479/2968). Predictors of CI-AKI were contrast volume, white blood cell count, left anterior descending infarct-related artery, age, anaemia, creatinine clearance <60 mL/min, and history of congestive heart failure. Patients with CI-AKI had higher rates of net adverse clinical events [NACE; a combination of major bleeding or composite major adverse cardiac events (MACE; consisting of death, reinfarction, target vessel revascularization for ischaemia, or stroke)] at 30 days (22.0 vs. 9.3%; P < 0.0001) and 3 years (40.3 vs. 24.6%; P < 0.0001). They also had higher rates of mortality at 30 days (8.0 vs. 0.9%; P < 0.0001) and 3 years (16.2 vs. 4.5%; P < 0.0001). Multivariable analysis confirmed CI-AKI as an independent predictor of NACE [hazard ratio ([HR), 1.53; 95% confidence interval (CI), 1.23-1.90; P = 0.0001], MACE (HR, 1.56; 95% CI, 1.23-1.98; P = 0.0002), non-coronary artery bypass grafting major bleeding (HR, 2.07; 95% CI, 1.57-2.73; P < 0.0001), and mortality (HR, 1.80; 95% CI, 1.19-2.73; P = 0.005) at 3-year follow-up. CONCLUSION: Contrast-induced acute kidney injury is associated with poor short- and long-term outcomes after primary percutaneous coronary intervention in STEMI.

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 it
