IDA: iron deficiency anemia, IDA ferritin < 50 ng/ml: iron deficiency anemia with ferritin level less than 50, IDA ferritin > 50 ng/ml: iron deficiency anemia with ferritin level more than 50 ng/ml.
Table 4: Comparing ejection fraction (EF) and hemoglobin related parameters changes after treatment for anemia and heart failure. Iron deficiency anemia (IDA) patients were subdivided into two groups based on ferritin level. Data show a significant improvement in EF in patients with IDA with ferritin > 50 ng/ml compared to anemia of chronic disease, but improvement in EF in patients with IDA is independent of ferritin level.
