Advancing the Assessment of Cardiac Injury and Function
Bibliographic record
Abstract
While heart transplantation is the most effective therapeutic modality for end-stage heart failure, less than 50% of potential donors become actual heart donors.The main cause of donor heart underutilization is the maximum 4 h ischemic time allowed during mechanical arrest with cold storage, which limits the geographic distribution of hearts due to transportation time limitations.Importantly, prolonged ischemic time is an important risk factor for primary graft dysfunction (PGD), when the donor heart output is insufficient for organ perfusion.PGD is a significant challenge that occurs in 10%-20% of heart transplants.While the 1 month heart transplant mortality rate is approximately 8%, PGD accounts for 39% of these deaths.
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 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.
