Iron Deficiency in Heart Failure: A Scientific Statement from the Heart Failure Society of America

Area of Science:

• Cardiology
• Internal Medicine
• Nutritional Science

Background:

• Iron deficiency is prevalent in ~50% of symptomatic heart failure patients.
• It is linked to reduced functional capacity, quality of life, and increased mortality.
• Understanding iron deficiency is crucial for managing heart failure outcomes.

Purpose of the Study:

• To review the definition, epidemiology, and pathophysiology of iron deficiency in heart failure.
• To discuss pharmacological considerations for iron repletion therapies.
• To summarize clinical trial evidence on iron repletion strategies in heart failure.

Main Methods:

• Literature review of current knowledge on iron deficiency in heart failure.
• Analysis of epidemiological data and pathophysiological mechanisms.
• Synthesis of evidence from clinical trials on iron repletion.

Main Results:

• Iron deficiency is common and significantly impacts heart failure patient prognosis.
• Various pharmacological agents and strategies exist for iron repletion.
• Clinical trial data increasingly supports the benefits of iron repletion in select patients.

Conclusions:

• Iron deficiency is a critical comorbidity in symptomatic heart failure.
• Timely and appropriate iron repletion can improve patient outcomes.
• Further research and clinical guidelines are evolving to optimize iron management.
