Spontaneous coronary artery dissection (SCAD) as a rare but life-threatening emergency department presentation: a case report
Bibliographic record
Abstract
Spontaneous coronary artery dissection (SCAD) is a rare but life-threatening cause of acute coronary syndrome, particularly in young women with few traditional risk factors for atherosclerosis. SCAD is often underrecognized due to its atypical presentation which can lead to misdiagnosis or delayed diagnosis in emergency settings. We present a case of a 40-year-old female who presented to the emergency department with acute chest pain and was found to have ST-elevation myocardial infarction (STEMI) due to SCAD. This case highlights the importance of considering SCAD in the differential diagnosis of acute coronary syndrome in young patients, especially females, and the need for increased awareness among emergency physicians to optimize patient outcomes and reduce recurrence risks. This case also emphasizes the importance of recognizing SCAD as a distinct entity from atherosclerotic ACS, as it requires a different management approach, particularly in the initial steps of care.

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; both teacher heads agree on what is shown here.
