Abstract

Objectives: To investigate the prevalance of iron-deficiency anemia in patients of chronic heart failure with reduced ejection (HFrEF) and the relationship between the degree of iron deficiency anemia with other factors.

Methods: A prospective cross-sectional study.

Results: The prevalance of iron deficiency anemia in HFrEF patients was 31.0%. The average age was 64.9 years old, the male/female ratio was 0.8. Increased age, severe heart failure (NYHA III-IV), and decreased of renal function were associated with the severity of iron-deficiency anemia in HFrEF patients. The left ventricular ejection fraction (EF) in HFrEF patients with severe iron-deficiency anemia was significantly higher than that of mild iron-deficiency anemia. The 3-month re-hospitalization rate was 45.5%. Moderate-severe iron-deficiency anemia (Hb < 10 mg/dL) is an independent risk factor for increased 3-months re-hospitalization in patients of HFrEF, after adjusting to other risk factors (age over 60 years, NYHA III-IV, eGFR < 60 mL/min/1.73m2).

Conclusion: Iron-deficiency anemia is one of the comorbidities that need attention in HFrEF patients. Moderate-severe iron-deficiency anemia (Hb < 10 mg/dL) is an independent risk factor for increased 3-month hospital readmission rate.
