Anemia and Iron Deficiency in Heart Failure: Clinical and Prognostic Role

Area of Science:

• Cardiology
• Internal Medicine
• Hematology

Background:

• Anemia and iron deficiency (ID) are prevalent comorbidities in patients with heart failure (HF).
• Both conditions significantly correlate with reduced functional capacity and predict a poorer prognosis in HF patients.
• Despite their impact, anemia and ID are frequently overlooked in routine cardiology practice.

Purpose of the Study:

• To review the prevalence of anemia and ID in heart failure.
• To summarize the pathophysiologic mechanisms linking anemia and ID to HF severity.
• To explore the relationship between anemia, ID, exercise capacity, and prognosis in HF.

Main Methods:

• Literature review summarizing existing research on anemia and iron deficiency in heart failure.
• Analysis of pathophysiologic mechanisms connecting these conditions to heart failure outcomes.
• Focus on the impact on exercise capacity and overall prognosis.

Main Results:

• Anemia and iron deficiency are common and interrelated in heart failure patients.
• These conditions negatively affect exercise capacity and are associated with worse prognosis.
• The review highlights the underdiagnosis and under-management of these comorbidities.

Conclusions:

• Anemia and iron deficiency represent significant, often underestimated, contributors to poor outcomes in heart failure.
• Increased clinical awareness and systematic screening for anemia and ID are crucial in HF management.
• Addressing these deficiencies may improve functional capacity and prognosis in heart failure patients.
