Abstract

fetched live from OpenAlex

La cardiomyopathie ischémique et l’insuffisance cardiaque (IC) sont deux des principales causes de morbidité et de mortalité dans les pays industrialisés. L’IC représente la condition finale résultant de plusieurs pathologies affectant le myocarde. Au Canada, plus de 400 000 personnes souffrent d’IC. Malgré la grande variété de traitements disponibles pour prendre en charge ces patients à haut risque de mortalité, l’évolution et le pronostic clinique de cette population demeurent sombres. Les thérapies de régénération par transplantation cellulaire représentent de nouvelles approches pour traiter les patients souffrant d’IC. L’impact de cette approche cellulaire et les mécanismes qui sous-tendent l’application de ce nouveau mode de traitement demeurent obscurs. Les hypothèses proposées dans cette thèse sont les suivantes : 1) l’évolution à long terme des patients qui se présentent en IC grave est nettement défavorable malgré les techniques actuelles de revascularisation chirurgicale à cœur battant; 2) la thérapie cellulaire et, plus spécifiquement, l’injection intracoronaire précoce de milieu de culture cellulaire, permet d’améliorer la récupération fonctionnelle du ventricule gauche suite à un infarctus aigu du myocarde; et 3) la mobilisation de l’axe cœur-moelle osseuse constitue un mécanisme de réponse important lors de la survenue d’un événement ischémique chronique affectant le myocarde.

Not 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.
