When do you opt to administer IV iron for patients with heart failure who may also have anemia of chronic disease or at risk for iron deposition disease?

I do not hesitate to administer IV iron in a patient with heart failure (chronic inflammation) if serum ferritin levels are <30 ng/ml and TSAT is under 20%. This is the only way, besides blood transfusions, to improve Hgb levels in this patient population.
