The Effects of Low-Dose Versus High-Dose Intravenous IRON Therapy With Ferric DerisomaltOSE in Patients With Chronic Heart Failure and Iron Deficiency

"After baseline assessment, participants will be randomized in a 1:1 ratio to receive a high-dose IV iron regimen and a low-dose IV iron regimen. After the initial iron repletion, ferritin concentration and TSAT were measured every three months and the results used to determine the dose of ferric derisomaltose during follow-up.~In the high-dose group, participants will receive repeat iron dosing as long as the serum ferritin was not \>700 ng/mL, or if TSAT was not \>40% during follow-up."

In the low-dose group, participants will receive repeat iron dosing if ferritin \<100 ng/mL or if ferritin 100-300 ng/mL and TSAT \>20% during follow-up.
