Effects of Pharmacologic Therapy on Health-Related Quality of Life in Elderly patients with Atrial Fibrillation: A systematic Review of Randomized and Nonrandomized Trials
Bibliographic record
Abstract
This systematic review assessed the impact of atrial fibrillation (AF) and pharmacotherapy on health-related quality of life (HRQOL) in elderly patients. Highly prevalent in the elderly, AF is associated with morbidity and symptoms affecting HRQOL. A PubMed and EMBASE search (1999-2010) was conducted using the terms atrial fibrillation, elderly, quality of life, Medicare, and Medicaid. In all, 504 articles were identified and 15 were selected (studies examining pharmacotherapy [rate or rhythm control] and HRQOL in AF patients with a mean age ≥ 65 years). Information, including study design, cohort size, and HRQOL instruments utilized, was extracted. Five observational studies, 5 randomized trials comparing rate and rhythm control, 3 randomized trials investigating pharmacologic agents, and 2 trials examining HRQOL, depression, and anxiety were identified. Elderly AF patients had reduced HRQOL versus patients in normal sinus rhythm, particularly in domains related to physical functioning. HRQOL may be particularly affected in older AF patients. Although data do not indicate whether a pharmacologic intervention or single treatment strategy-namely rate versus rhythm control-is better at improving HRQOL, either of these strategies and many pharmacologic interventions may improve HRQOL in elderly AF patients. Based on reviewed data, an algorithm is suggested to optimize HRQOL among elderly patients.

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.
