Iron Deficiency in Heart Failure: From ESC Guidelines to Clinical Practice at a Romanian Hospital

Year: 2025

Type: article

Abstract: Background: Iron deficiency (ID) is a frequent comorbidity in heart failure (HF), associated with reduced functional capacity and poor prognosis. Although the European Society of Cardiology (ESC) guidelines recommend systematic screening and intravenous iron supplementation (IS), adherence in clinical practice remains limited. This observational study aimed to evaluate how these recommendations are implemented into practice. Methods: We performed a retrospective study including 4348 patients hospitalized with HF (NYHA II-IV) in a tertiary internal medicine clinic in Eastern Europe between January 2018 and September 2022. Demographic data, comorbidities, laboratory parameters, echocardiographic findings were collected from electronic medical records. IS was defined as serum ferritin < 100 ng/mL. Results: Among HF patients, 2547 (58.7%) were screened for ID, and 1091 (42.8%) had absolute deficiency. Only 278 patients (25.5%) received intravenous ferric carbodymaltose. Treated patients were predominantly elderly (70.1% ≥ 70 years), female (60.4%), and often had ischemic or valvular disease. Patients receiving intravenous IS showed higher NT-proBNP and troponin levels. A progressive increase in IS use was observed during the study period, with a temporary decline during the COVID-19 pandemic. Conclusions: Despite relatively high screening rates, only one-quarter of HF patients with confirmed ID received intravenous IS. These findings highlight persistent gaps between guidelines and clinical practice, emphasizing the need for improved awareness and implementation of ESC recommendations to optimize outcomes in HF patients with ID.
