Why the study?
The study was conducted to evaluate the effects of iron deficiency anaemia on the functional status of patients with heart failure with reduced ejection fraction.
Does iron deficiency anemia impair functional status and quality of life in adult patients with chronic HFrEF?
Population
320 adult patients with chronic HFrEF
Comparison
IDA vs non-IDA
Design
Analytical cross-sectional study
Key result
Iron deficiency anemia in patients with HFrEF was associated with significantly lower 6-minute walk test distance (280.98 vs. 303.32 m, p<0.001) and KCCQ scores (42.72 vs. 47.28, p<0.001).

Does iron deficiency anemia impair functional status and quality of life in adult patients with chronic HFrEF?
Absolute Event Rate: 280.98% vs 303.32%
p-value: p=<0.001
Iron deficiency anemia is highly prevalent in HFrEF patients and is associated with significantly impaired functional capacity and quality of life.
Hassan et al. (2026) conducted a cross-sectional in Heart failure with reduced ejection fraction (HFrEF) (n=320). Iron deficiency anemia vs. Non-iron deficiency anemia was evaluated on 6-minute walk test (6MWT) distance (p=<0.001). Iron deficiency anemia in patients with HFrEF was associated with significantly lower 6-minute walk test distance (280.98 vs. 303.32 m, p<0.001) and KCCQ scores (42.72 vs. 47.28, p<0.001).
