[Cognitive functions in patients with chronic heart failure].
Bibliographic record
Abstract
OBJECTIVE: To evaluate cognitive functions in patients with different stages of chronic heart failure (CHF) and different degrees of stenosis of precerebral arteries. MATERIAL AND METHODS: Authors examined 148 patients with CHF and 21 patients without CHF (controls). Neuropsychological assessment (NINDS-Canadian Stroke Standards - 30 minutes protocol), ultrasound scanning of the main cranial arteries and transcranial dopplerography and echocardiogram were made. RESULTS AND CONCLUSION: Patients with CHF more frequently had combined (multifocal) cognitive impairment. Patients with systolic heart failure performed significantly worse on neuropsychological tests, in particular, functional domains within the frontal lobes and "executive" dysfunction, than those with diastolic heart failure. Cognitive impairment in patients with CHF was associated with the lower left ventricular ejection fraction and deterioration in indices of diastolic function but not with carotid artery stenosis.

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.
