Hierro e insuficiencia cardiaca

Abstract

Resumen La deficiencia de hierro se ha convertido en un nuevo objetivo para mejorar los resultados funcionales en pacientes con insuficiencia cardiaca, y las preparaciones intravenosas parecen ser el unico tratamiento eficaz para ese proposito. Sin embargo, esta lejos de entenderse la relacion existente entre el hierro y el oxigeno en esta poblacion, ya que por lo general la hepcidina esta regulada al alza, lo que evita posiblemente la disponibilidad de hierro y el dano en el contexto de un exceso de estres oxidativo. Los marcadores empleados para detectar la deficiencia de hierro tisular en el laboratorio son altamente dependientes de las necesidades de sintesis de hemoglobina, por lo que el primer objetivo racional en cualquier intento de terapia con hierro es alcanzar el pico de hemoglobina para cada individuo. Un subgrupo de pacientes tratados con hierro intravenoso pueden mostrar un peor resultado en cuanto a ingresos hospitalarios y mortalidad cuando se comparan con un grupo placebo, lo que senala que los umbrales de laboratorio utilizados para detectar deficiencias de hierro en la insuficiencia cardiaca son altamente sensibles pero menos especificos en la identificacion de los pacientes que no se beneficiarian de esta terapia. Por lo tanto, se podria recomendar un suministro gradual de hierro a lo largo del tiempo con una medicion paralela de su incorporacion para la sintesis de hemoglobina para satisfacer las necesidades de los tejidos. La terapia oral estandar con hierro no debe descartarse en pacientes con insuficiencia cardiaca con anemia y reservas de hierro agotado (ferritina
