The main study outcome was the percentage of patients with ID (ferritin &amp;lt;100 \u03bcg\/L = absolute ID or ferritin 100\u2013299 \u03bcg\/L and transferrin saturation &amp;lt;20% = functional ID) at admission (T0), after clinical stabilization prior to discharge (T1), and 10 \u00b1 6 weeks after discharge (T2). At T0, ID was present in 71.8% of the patients (44.1% absolute and 27.7% functional ID). At T1 and T2, ID was present in 56.4% (32.4% absolute and 24% functional ID) and 50.3% (36.8% absolute and 13.5% functional ID), respectively. Absolute ID persisted from T0 to T2 in 66% of the patients, while functional ID resolved in 56% of the patients. Ferritin (median [interquartile range] 124 \u03bcg\/L [56\u2013247] to 150 \u03bcg\/L [73\u2013277]), transferrin saturation (15% [10\u201320] to 18% [12\u201327]), and iron levels (9 \u03bcmol\/L [6\u201313] to 11 \u03bcmol\/L [8\u201316]) increased significantly (all P &amp;lt; 0.001) from T0 to T1. Transferrin saturation (to 21% [15\u201329]) and iron levels (to 13 \u03bcmol\/L [9\u201317]) also increased significantly (both P &amp;lt; 0.01) from T1 to T2 without iron supplementation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Iron deficiency is highly prevalent in patients with AHF, but resolves during treatment in some patients, even without iron supplementation.
