About

HF4HF

Features
Read full description

El estudio "HF4HF" evalúa si una dieta alta en grasas puede mejorar la función cardíaca en pacientes con insuficiencia cardíaca no isquémica y fracción de eyección reducida. En este ensayo, pacientes de España, Italia, Francia y Rumanía seguirán una dieta alta en grasas o una dieta estándar. Se medirá el impacto en la función cardíaca, a través de varios parámetros, entre los que está la fracción de eyección del ventrículo izquierdo, utilizando técnicas avanzadas de imagen. Los investigadores buscan determinar si la dieta mejora la función cardíaca sin efectos negativos, como lo son alteraciones en los niveles de colesterol o la función hepática. Si tiene éxito, este enfoque dietético podría ofrecer una opción no farmacológica para mejorar la salud cardiovascular en pacientes con miocardiopatía dilatada e insuficiencia cardíaca.
