Sonothrombolysis Augments Reperfusion in ST-Elevation Myocardial Infarction With Primary Percutaneous Coronary Intervention: Insights From the SONOSTEMI Study
Bibliographic record
Abstract
Reperfusion injury is common following primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction. In a prospective Canadian single-arm study of 15patients, the use of myocardial contrast echocardiography with high mechanical index ultrasound impulses (sonothrombolysis) initiated prior to primary PCI resulted in 7 patients with pre-PCI thrombolysis in myocardial infarction-2/3 flow (46.7%). Following reperfusion, all 15 patients had thrombolysis in myocardial infarction-3 flow, and 14 patients achieved ST-segment resolution ≥ 50% at 30 minutes post-PCI (93.3%). At 90 days, 12 patients had normal left ventricular ejection fraction ≥ 50% (80.0%). Our results demonstrate the feasibility of a novel technique to enhance reperfusion in ST-elevation myocardial infarction and provide a rationale for a randomized Canadian study.

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.
