Abstract

fetched live from OpenAlex

Introduccin: La miocardiopata cirrtica (MCC) est definida como una disfuncin miocrdica crnica en pacientes con cirrosis y ausencia de otra enfermedad cardiaca, es una entidad subclnica y un importante factor pronostico posterior al trasplante heptico. Los criterios diagnsticos para MCC se propusieron en el Congreso de Gastroenterologa de Montreal 2005, los cuales han sido actualizados el 2019 por el Consorcio de Miocardiopata Cirrtica. En Chile, no existen a la fecha cohortes publicadas con los nuevos criterios. Objetivos: Caracterizar y evaluar la presencia de Miocardiopata Cirrtica en pacientes en lista de espera para trasplante heptico del Hospital del Salvador (HDS) de Santiago de Chile, con los distintos criterios diagnsticos y como cambia su prevalencia. Metodologa: Cohorte histrica de pacientes adultos cirrticos en estudio previo a trasplante heptico del HDS. Se incluyeron pacientes con estudio ecocardiogrfico y sin enfermedad cardiaca intrnseca. Se realiz anlisis descriptivos de variables demogrficas y clnicas, MELD-Na, Child Pugh Score (CPS), entre otros. Las variables ecocardiogrficas, evaluadas segn criterios del 2005 y actuales. El anlisis estadstico de datos realizado mediante software (Stata15 y test de McNemar). Resultados: 102 pacientes cumplieron con criterios de elegibilidad. 52% son hombres y promedian 59 aos. El 34% CPS grado C. Un MELD-Na promedio de 18 puntos. Bajo criterios diagnsticos del 2005 se presenta mayor prevalencia general de MCC versus criterios 2019; (73,27% vs 10,89%). Mayor disfuncin diastlica en comparacin al 2019; 78,43% y 10,78% respectivamente. Asimismo, mayor disfuncin sistlica con criterios 2005 en comparacin con 2019 (8,82% vs 6,86%). Conclusiones: La implementacin de los actuales criterios representa un cambio estadsticamente significativo en el nmero de pacientes diagnosticados con MCC. As mismo, en el nmero de pacientes diagnosticados con disfuncin diastlica. Esta significancia estadstica no se representa en diagnstico de disfuncin sistlica. Los resultados expuestos son compatibles a los informados por estudios internacionales.

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.
