BackgroundAlthough a potentially important pathophysiologic factor in heart failure, the prevalence and predictors of anemia have not been well studied in unselected patients with heart failure.MethodsThe Study of Anemia in a Heart Failure Population (STAMINA-HFP) Registry prospectively studied the prevalence of anemia and the relationship of hemoglobin to health-related quality of life and outcomes among patients with heart failure. A random selection algorithm was used to reduce bias during enrollment of patients seen in specialty clinics or clinics of community cardiologists with experience in heart failure. In this initial report, data on prevalence and correlates of anemia were analyzed in 1,076 of the 1,082 registry patients who had clinical characteristics and hemoglobin determined by finger-stick at baseline.ResultsOverall (n = 1,082), the registry patients were 41% female and 73% white with a mean age (±SD) of 64 ± 14 years (68 ± 13 years in community and 57 ± 14 years in specialty sites, P < .001). Among the 1,076 patients in the prevalence analysis, mean hemoglobin was 13.3 ± 2.1 g/dL (median 13.2 g/dL); and anemia (defined by World Health Organization criteria) was present in 34%. Age identified patients at risk for anemia, with 40% of patients >70 years affected.ConclusionsInitial results from the STAMINA-HFP Registry suggest that anemia is a common comorbidity in unselected outpatients with heart failure. Given the strong association of anemia with adverse outcomes in heart failure, this study supports further investigation concerning the importance of anemia as a therapeutic target in this condition.
