Abstract

fetched live from OpenAlex

Reperfusion alone during acute myocardial infarction (AMI) preserves left ventricular (LV) topography but causes 'stunning', with delayed or no recovery of function. To determine whether adjunctive intravenous nitroglycerin (NTG) accelerates functional recovery, we prospectively measured function and topography by repeated two-dimensional echocardiography between 1 day and 6 months in 5 groups of patients (n = 73) with a first AMI: placebo (group 1), NTG alone (group 2), NTG combined with successful reperfusion after 4 h (group 3) or failed reperfusion (group 4), and successful reperfusion alone (group 5). Asynergy decreased promptly (p < 0.001) and ejection fraction improved (p < 0.001) between day 1 and 6 months in groups 2 and 3 compared to baseline and groups 1, 4 and 5. Infarct expansion and thinning found in group 1 were prevented in groups 2, 3, 4 and 5. Diastolic volume increased in the anterior subgroup 1 but not 2, 3, 4 and 5. This is the first demonstration that reperfusion combined with adjunctive NTG produces earlier, greater and persistent recovery of LV function in addition to attenuation of remodeling in patients after AMI.

Teacher imitation

Not 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.
