One‐year outcomes of supersaturated oxygen therapy in acute anterior myocardial infarction: The IC‐HOT study
Bibliographic record
Abstract
Abstract Background Supersaturated oxygen (SSO 2 ) has recently been approved by the U.S. Food and Drug Administration for administration after primary percutaneous coronary intervention (pPCI) in patients with anterior ST‐segment elevation myocardial infarction (STEMI) based on its demonstration of infarct size reduction in the IC‐HOT study. Objectives To describe the 1‐year clinical outcomes of intracoronary SSO 2 treatment after pPCI in patients with anterior STEMI. Methods IC‐HOT was a prospective, open‐label, single‐arm study in which 100 patients without cardiogenic shock undergoing successful pPCI of an occluded left anterior descending coronary artery were treated with a 60‐min SSO 2 infusion. One‐year clinical outcomes were compared with a propensity‐matched control group of similar patients with anterior STEMI enrolled in the INFUSE‐AMI trial. Results Baseline and postprocedural characteristics were similar in the two groups except for pre‐PCI thrombolysis in myocardial infarction 3 flow, which was less prevalent in patients treated with SSO 2 (9.6% vs. 22.9%, p = .02). Treatment with SSO 2 was associated with a lower 1‐year rate of the composite endpoint of all‐cause death or new‐onset heart failure (HF) or hospitalization for HF (0.0% vs. 12.3%, p = .001). All‐cause mortality, driven by cardiovascular mortality, and new‐onset HF or HF hospitalization were each individually lower in SSO 2 ‐treated patients. There were no significant differences between groups in the 1‐year rates of reinfarction or clinically driven target vessel revascularization. Conclusions Infusion of SSO 2 following pPCI in patients with anterior STEMI was associated with improved 1‐year clinical outcomes including lower rates of death and new‐onset HF or HF hospitalizations.

How this classification was reachedexpand
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.
