Abstract

fetched live from OpenAlex

Aging is one of the most significant risk factors for the development of atrial fibrillation, and given our aging population, this is likely to present a major public health challenge in the coming years. Although the specific mechanisms underlying this association remain poorly understood, several biological processes including fibrosis, DNA damage, chromatin remodeling, amyloid deposition, mitochondrial dysfunction, and inflammation have been implicated in the structural and functional deterioration that leads to the development of atrial fibrillation. Herein, we review work from the last several years that has contributed to our understanding of the link between aging and atrial fibrillation with a focus on the basic pathophysiological mechanisms. We also outline areas for future research aimed at better characterizing this complex relationship.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
