Abstract 20833: Extension and Recurrence of Spontaneous Coronary Artery Dissection
Bibliographic record
Abstract
Aims: Spontaneous coronary artery dissection (SCAD) is an under-recognized and important cause of myocardial infarction in young women. Recurrent SCAD is frequent but poorly understood. We aim to explore the clinical and angiographic characteristics, and outcomes of recurrent SCAD. Methods and Results: Patients with SCAD extension or recurrence prospectively followed at Vancouver General Hospital were included. SCAD diagnosis was confirmed by 2 experienced cardiologists. Detailed medical history, baseline demographics, angiographic results, and clinical details of index SCAD and recurrent events were recorded. SCAD extension was defined as angiographic extension of previously dissected coronary segment, and recurrent SCAD was defined as de novo spontaneous dissection. We identified 43 patients with SCAD extension or recurrence with mean age 48.9±8.4 years, 38/43 were women, and 32/43 had fibromuscular dysplasia. Nine patients had SCAD extension at median time of 5 (1-19) days, while 34 patients had recurr...

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.
