Cognitive Impairment in Patients With Advanced Heart Failure and Its Implications on Decision-Making Capacity
Bibliographic record
Abstract
Cognitive impairment (CI) is a multifaceted entity that entails more than just memory loss. Deficits in other domains, most importantly executive function, can have profound effects on health outcomes in afflicted patients. The prevalence of CI among the heart failure population is exceedingly high, and even higher so among patients with advanced heart failure (AHF). These patients display consistent declines in memory, attention, psychomotor abilities, and executive function. Such deficits interfere with patients' abilities to recognize worsening symptoms, adhere to complex medication regimens, and make sound decisions pertaining to medical care. Regular evaluation of cognitive status using instruments such as the Montreal Cognitive Assessment is a fast, reliable method that allows physicians who treat patients with AHF to anticipate these obstacles to treatment and act accordingly. Referral for more comprehensive neuropsychological evaluation should be considered for patients with unexplained declines from baseline, legal determination of competence, and for heart transplant or ventricular assist device placement candidates.

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.
