BACKGROUND: Anemia is a serious and highly prevalent co-morbidity in chronic heart failure (HF) patients. Its influence on health-related quality of life (HR-QoL) has rarely been studied, and no data is available regarding the role it plays in hospitalized HF patients. METHODS: Baseline data from the COACH study (Coordinating study evaluating Outcomes of Advising and Counselling in Heart Failure) were used. HR-QoL was assessed by means of generic and disease-specific questionnaires. Analyses were performed using ANOVA and ANCOVA, with covariates of age, gender, eGFR, diabetes, and NYHA class. RESULTS: In total, 1013 hospitalized patients with a mean age of 71 (SD 11) years were included; 70% of these patients had no anemia (n=712), 14% had mild anemia (n=141), and 16% had moderate-to-severe anemia (n=160). Independent associations were found between anemia and physical functioning (p=0.019), anemia and role limitations due to physical functioning (p=0.002), anemia and general health (p=0.024), and anemia and global well-being (p=0.003). CONCLUSION: In addition to the burden of HF itself, anemia is an important factor which influences HR-QoL in hospitalized HF patients, and one that is most pronounced in the domain related to physical functioning and general health.
