The purpose of this study is to better understand how body levels of iron affect the ability
to exercise in patients with heart failure.
Heart failure is a condition in which abnormal pumping action of the heart reduces the flow
of blood to the body. Patients with heart failure may feel shortness of breath or leg fatigue
when they exercise. Iron is an essential nutrient in the diet. In heart failure patients, low
body levels of iron might increase shortness of breath and fatigue.

The purpose of this prospective, double blind parallel group randomized study is to compare
the effects of ferric carboxymaltose vs. placebo on skeletal muscle mitochondrial oxidative
capacity, submaximal exercise tolerance, and health-related quality of life in non-anemic
Heart Failure (HF) patients with functional iron deficiency.
