Deep dives

The Prevalence and Impact of Iron Deficiency in Heart Failure

Iron deficiency is highly prevalent among patients with heart failure, affecting roughly 50% to 60% of this population regardless of ejection fraction. This condition is associated with significantly worse outcomes, including lower quality of life, diminished functional status, and increased rates of hospitalizations and mortality. Studies indicate that patients often face nutritional challenges that lead to insufficient iron intake, coupled with systemic factors like inflammation that hinder iron absorption. Additionally, medications such as blood thinners further exacerbate iron deficiency by increasing blood loss, demonstrating the critical need for regular screening and effective management of iron levels in heart failure patients.
