Simultaneous Thrombosis in a Normal Left Ventricle and Normal Carotid Artery in a Patient With a Stroke Secondary to Iron Deficiency Anemia
Bibliographic record
Abstract
Iron deficiency anemia (IDA) is implicated as a cause of stroke, particularly in young patients without cardiovascular disease. In such patients, thrombi sometimes form in carotid arteries or the aorta. We report here a patient with a stroke secondary to IDA with thrombi in the normal left ventricle and normal carotid artery. The patient was a 45-year-old woman with severe IDA who developed cerebral infarction in the right middle cerebral artery. She had no other thrombophilia or cardiovascular diseases. Echocardiography showed a left ventricular thrombus without cardiac disease, and the carotid ultrasound showed a mobile thrombus attached to the right internal carotid artery without atherosclerosis. Antithrombotic therapy with iron supplementation removed both thrombi within 2 weeks. This is the first case of IDA with a ventricular thrombus in a normal heart. This case identifies a new site for thrombosis in IDA and shows that patients with IDA may present with simultaneous thrombosis at separate sites. IDA must therefore be recognized as a cause of stroke or systemic embolism, particularly in patients without detectable cardiovascular disease. In such patients, it is important to conduct careful investigations to detect thrombosis. J Med Cases. 2014;5(6):351-354 doi: http://dx.doi.org/ 10.14740 /jmc1786w

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; a candidate call from one teacher head, not a consensus.
