:Patients with heart failure (HF) with iron deficiency (ID) have worse New York Heart Association class and are at a higher risk of recurrent hospitalizations. Intravenous (IV) iron has been shown to improve exercise ability and reduce hospitalizations. IV sodium ferric gluconate complex (SFGC) has been found to be safe and affordable but has not been studied in this population in a randomized trial. This was a prospective, single-blind, investigator-initiated, randomized controlled trial. Patients admitted for acute heart failure with ID were randomly assigned 1:1 to receive IV SFGC on top of optimal medical treatment. The primary outcome was the change in the 6-minute walk test (6MWT) from baseline to 3 and 6 months. Between September 2019 and May 2021, 34 patients were randomized. 19 patients (55%) were randomized to the treatment arm receiving 125 mg of IV SFGC per day for 3–5 days. COVID-19 was a major barrier to the implementation of the study follow-up protocol, which caused the study to end early. Both groups of patients had similar clinical characteristics, comorbidities, median left ventricular ejection fraction, and rate of death and readmissions due to HF. A higher level of NT-proBNP was observed in patients treated with IV iron (7902 pg/mL vs. 3158, P = 0.04). There was no difference in 6MWT change between groups at 3 months (improvement of 21.6 vs. 24.1 meters) or 6 months (−5 meters vs. 46 meters). In conclusion, IV SFGC–treated patients had a comparable 6-minute walk at 3 and 6 months despite suffering from more severe HF with higher baseline NT-proBNP (NCT04063033).
Background: Patients suffering from heart failure (HF) and iron deficiency (ID) have worse outcomes. Treatment with intra-venous (IV) ferric carboxymaltose has been shown to reduce HF rehospitalizations and to improve functional capacity and symptoms in patients with HF and reduced ejection fraction (HFrEF). However, IV ferric carboxymaltose is significantly more expensive than IV sodium ferric gluconate complex (SFGC) limiting its availability to most HF patients around the globe. Methods: A retrospective analysis comparing patients admitted to internal medicine or cardiology departments between January 2013 to December 2018 due to acute decompensated HF (ADHF) and treated with or without IV SFGC on top of standard medical therapy. Results: During the study period, a total of 1863 patients were hospitalized due to ADHF with either HFrEF or HF with preserved ejection fraction (HFpEF). Among them, 840 patients had laboratory evidence of iron deficiency (absolute or functional) and met the inclusion criteria. One hundred twenty-two of them (14.5%) were treated with IV SFGC during the index hospitalization. Patients treated with IV iron were more likely to have history of ischemic heart disease, atrial fibrillation, and chronic kidney disease. The rate of readmissions due to ADHF was similar between the groups at 30 days, 3 months, and 1 year. Conclusion: High risk patient hospitalized to ADHF and treated with IV SFGC showed comparable ADHF readmission rates, compared to those who did not receive iron supplementation.
Introduction Patients suffering from heart failure (HF) and iron deficiency (ID) have worse outcomes. Intra-venous (IV) ferric carboxymaltose has been shown to reduce HF readmissions and improve symptoms in patients with HF with reduced ejection fraction. However, IV ferric carboxymaltose is significantly more expensive than IV Sodium Ferric Gluconate Complex limiting its availability to most HF failure patients around the globe. Methods This is a retrospective analysis comparing patients admitted due to acute decompensated HF (ADHF) and treated with or without IV sodium ferric gluconate complex on top of standard medical therapy. The study included all patients admitted due to ADHF, with either reduced or preserved EF between January 2013 to December 2018. Results During the study period, a total of 1856 patients were admitted due to ADHF. Among them 840 patients had an indication for IV iron therapy. Among them 122 (14.5%) patients were treated with IV Sodium Ferric Gluconate during hospitalisation. When comparing the group that was treated with IV iron compared to standard HF treatment no difference was found at one year after the hospitalization regarding reduction in readmissions due to ADHF (27.9% vs 24.8% respectively P=0.54), nor in all-cause mortality (25.4% vs. 25.6% respectively, P=0.99). Conclusion Treatment with IV Sodium ferric gluconate complex during hospitalization due to ADHF did not show any advantage in reduction of readmission due to heart failure after 1 year follow up.
