Sleep Apnea in Patients With Transient Ischemic Attack and Minor Stroke
Bibliographic record
Abstract
BACKGROUND AND PURPOSE: Patients with TIA and minor stroke are at high risk for recurrent stroke. Obstructive sleep apnea (OSA) may increase this risk. The objectives of our study were to determine the prevalence and severity of OSA and its clinical presentation in this population. METHODS: Patients who presented with TIA and minor stroke completed a questionnaire and nocturnal cardiopulmonary monitoring to diagnose OSA and associated nocturnal hypoxia. RESULTS: Sixty-six patients completed the study; 62% had OSA (respiratory disturbance index > 5). Forty-four percent of these patients had moderate or severe OSA (respiratory disturbance index > 15) that was associated with significant nocturnal hypoxia. Most patients did not have the typical clinical features of OSA, such as obesity and daytime sleepiness. CONCLUSIONS: Patients who experience TIA and minor stroke have a high prevalence of OSA and associated hypoxia. The atypical clinical presentation of OSA in this patient population may lead to under-recognition and treatment. Further studies are required to determine the impact of treating OSA on the risk of recurrent stroke.

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.
