Iron deficiency (ID) is present in approximately 50% of patients with heart failure (HF) and even higher prevalence rate up to 80% in post-acute HF setting. The current guidelines for HF recommend intravenous (IV) iron replacement in HF with reduced or mildly reduced ejection fraction and ID based on clinical trials showing improvements in quality of life and exercise capacity, and an overall treatment benefit for recurrent HF hospitalization. However, several barriers cause challenges in implementing IV iron supplementation in practice due, in part, to clinician knowledge gaps and limited resource availability to protocolize routine utilization in appropriate patients.

The challenges to academic and professional development and career advancement of women in cardiology (WIC), imposed by the pandemic, not only impinge the female cardiologists' "leaky pipeline" but also make the "leakiness" more obvious. This consensus document aims to highlight the pandemic challenges WIC face, raise awareness of the gender equity gap, and propose mitigating actionable solutions derived from the data and experiences of an international group of female cardiovascular clinicians and researchers. This changing landscape has led to the need for highly specialized cardiologists who may have additional training in critical care, imaging, advanced heart failure, or interventional cardiology.
