Changes in myocardial iron content following administration of intravenous iron (Myocardial‐IRON): Study design

Treatment with intravenous ferric carboxymaltose (FCM) has been shown to improve symptoms, functional capacity, and quality of life in patients with heart failure and iron deficiency. However, the underlying mechanisms for these beneficial effects remain undetermined. The aim of this study is to quantify cardiac magnetic resonance changes in myocardial iron content after administration of intravenous FCM in patients with heart failure and iron deficiency and contrast them with parameters of heart failure severity. This is a multicenter, double-blind, randomized study. Fifty patients with stable symptomatic heart failure, left ventricular ejection fraction <50%, and iron deficiency will be r…

Short‐term changes in left and right systolic function following ferric carboxymaltose: a substudy of the Myocardial‐IRON trial

Funding: This work was supported in part by an unrestricted grant from Vifor Pharma and Proyectos de Investigación de la Sección de Insuficiencia Cardiaca 2017 from Sociedad Española de Cardiología. The mechanisms underlying the beneficial effect of ferric carboxymaltose (FCM) in patients with heart failure (HF) and iron deficiency (ID) have not been completely characterized. The Myocardial-IRON trial was a double-blind, randomized trial that evaluated myocardial iron repletion following FCM vs. placebo in 53 patients with HF and ID. In this post hoc analysis, we evaluated whether treatment with FCM was associated with cardiac magnetic resonance changes in left and right ventricular functio…

Noninvasive Imaging Estimation of Myocardial Iron Repletion Following Administration of Intravenous Iron : The Myocardial- Trial

Background Intravenous ferric carboxymaltose ( FCM ) improves symptoms, functional capacity, and quality of life in heart failure and iron deficiency. The mechanisms underlying these effects are not fully understood. The aim of this study was to examine changes in myocardial iron content after FCM administration in patients with heart failure and iron deficiency using cardiac magnetic resonance. Methods and Results Fifty‐three stable heart failure and iron deficiency patients were randomly assigned 1:1 to receive intravenous FCM or placebo in a multicenter, double‐blind study. T2* and T1 mapping cardiac magnetic resonance sequences, noninvasive surrogates of intramyocardial iron, were eval…

Diuretic Strategies in Acute Heart Failure and Renal Dysfunction: Conventional vs Carbohydrate Antigen 125-guided Strategy. Clinical Trial Design

Abstract Introduction and objectives The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic str…

Estrategias diuréticas en insuficiencia cardiaca aguda con disfunción renal: terapia convencional frente a guiada por el antígeno carbohidrato 125. Diseño de ensayo clínico

Resumen Introduccion y objetivos El tratamiento optimo de pacientes con insuficiencia cardiaca aguda (ICA) y sindrome cardiorrenal tipo 1 (SCR-1) no esta bien definido. La hipoperfusion arterial y la congestion venosa tienen un papel fundamental en la fisiopatologia del SCR-1. El antigeno carbohidrato 125 (CA125) ha emergido como marcador indirecto de sobrecarga de volumen en la ICA. El objetivo de este estudio es evaluar la utilidad del CA125 para el ajuste del tratamiento diuretico de pacientes con SCR-1. Metodos Ensayo clinico multicentrico, abierto y paralelo, que incluye a pacientes con ICA y creatinina ≥ 1,4 mg/dl al ingreso, aleatorizados a: a)  estrategia convencional: titulacion ba…
