Prevalence and clinical implications of anemia in congestive heart failure patients followed at a specialized heart function clinic.

The objective of this study was to assess the prevalence of anemia and to investigate its association with comorbidities and its impact on clinical outcomes in patients with heart failure. The association of predefined anemia, as well as the correlation of serum hemoglobin level as a continuous variable, with outcomes of emergency department visits, hospitalization, and mortality was investigated. There were fewer anemic patients in New York Heart Association classes I and II than in classes III and IV.
