|Condition or disease||Intervention/treatment||Phase|
|Chronic Heart Failure||Drug: Ferric carboxymaltose infusion||Phase 1|
This study will obtain pilot feasibility data to explore the relationship between blood biomarkers of functional iron deficiency and skeletal muscle mitochondrial oxidative capacity with 31P-magnetic resonance spectroscopy (MRS) and imaging in heart failure patients.
Twenty (20) subjects will be recruited from the clinical practice of the NYU Advanced Cardiac Therapeutics group at NYU Langone Medical Center.
Twenty (20) subjects will be recruited from the practice of the NYU Advanced Cardiac Therapeutics group at NYU Langone Medical Center. The study will require a maximum of four (4) visits over a period of five (5) weeks. Eligibility for Visits 2-4 will be determined by the screening criteria in Visit 1. It is anticipated that 50% of the screened subjects at Visit 1 will be eligible to participate in Visit 2. Eligibility for participation in Visits 3 and 4 will be determined by the results of the iron biomarkers obtained at Visit 2. We anticipate that 50% of the subjects at Visit 2 will be eligible to participate in Visits 3 and 4. Only subject with functional iron deficiency will participate in Visits 3 and 4. There is no clinical care component for this study.

Drug: Ferric carboxymaltose infusion
Subjects with functional iron deficiency determined by the results of iron biomarker results at Visit 2 will receive a single dose of intravenous ferric carboxymaltose . The dose of Injectafer will be calculated from a modified Ganzoni equation adapted from previous heart failure clinical trials The maximum dose of Injectafer will be 750 mg. The calculated dose of Injectafer will be diluted in normal saline solution (4 mg/ml) and administered via a volumetric pump administered over 30 minutes.
- Biomarkers of iron stores [ Time Frame: 60 minutes ]Plantar flexion exercise as determined with a novel dynamic phosphorus magnetic resonance spectroscopy and imaging technique (31P-MRS & MRI) in heart failure patients (n=10) with and without functional iron deficiency. A spectrally selective three-dimensional turbo spin echo (3D-TSE) echo (3D-TSE) protocol for measurement of phosphocreatine recovery kinetics on a 3T Siemens MRI scanner as previously described (Siemens Medical Solutions, Erlangen, Germany).
- Skeletal muscle bioenergetics using 31P- MRS Spectroscopy [ Time Frame: 120 Minutes ]
Plantar flexion exercise with 31P-MRS and MRI in heart failure patients (n=5) with functional iron deficiency. A spectrally selective three-dimensional turbo spin echo (3D-TSE) protocol for measurement of phosphocreatine recovery kinetics on a 3T Siemens MRI scanner (Siemens Medical Solutions, Erlangen, Germany).
protocol for measurement of phosphocreatine recovery kinetics on a 3T Siemens MRI scanner as previously described (Siemens Medical Solutions, Erlangen, Germany).
- Functional Capacity [ Time Frame: Six Minutes ]Subjects will be asked to walk along a 30 meter marked path in a corridor at a self-selected pace. Subjects will receive standardized instruction before and during the walking test. The distance walked after 6 minutes (meters) will be recorded.
