Stroke secondary to post-partum coronary artery dissection.
Bibliographic record
Abstract
BACKGROUND: There is an increased risk of stroke during pregnancy and the puerperium. This risk is greatest in the post-partum period. Embolic sources secondary to cardiac abnormalities and cerebral arterial dissection are recognized as potential etiologies. CASE: A 32-year-old woman presented with left-sided weakness eight days post-partum. Imaging studies identified infarction in the territory of the right middle cerebral artery. Cardiac investigations revealed acute myocardial infarction secondary to dissection of the left main coronary artery. The patient underwent coronary artery bypass grafting with significant recovery of cardiac function. At two years post-presentation, her neurological deficits have resolved. DISCUSSION: Myocardial infarction secondary to coronary artery dissection has been long-recognized. Cerebral arterial dissection in association with pregnancy is also well-documented. This is a rare case of a patient presenting with stroke secondary to acute myocardial infarction secondary to coronary artery dissection.

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.
