Title: A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Assess the Efficacy and Safety of Darbepoetin Alfa Treatment on Mortality and Morbidity in Heart Failure (HF) Subjects With Symptomatic Left Ventricular Systolic Dysfunction and Anemia
Brief Summary: The purpose of the study is to determine the efficacy of treatment of anemia with darbepoetin alfa compared to placebo on the composite of time to death from any cause or first hospital admission for worsening heart failure in patients with symptomatic left ventricular systolic dysfunction and anemia.
