Why the study?
Anemia is common in heart failure across all LVEF levels, but its causes and associations with outcomes are complex and not fully understood.
Anemia is highly prevalent across the LVEF spectrum in heart failure and serves as an independent prognostic marker for increased mortality and morbidity.
Anemia may aid risk stratification across the LVEF spectrum in heart failure; leaves open optimal management strategies.
Anemia was common in heart failure, regardless of LVEF. Lower hemoglobin was associated with higher LVEF yet was an independent predictor of adverse mortality and morbidity outcomes. In heart failure, the causes of anemia and the associations between anemia and outcomes are probably multiple and complex.
