Randomized Controlled TrialErythropoietin improves anemia exercise tolerance and renal function and reduces B-type natriuretic peptide and hospitalization in patients with heart failure and anemia.
Anemia is now recognized as being a common finding in CHF and is associated with increased mortality and morbidity. However, it is uncertain whether the anemia is actually causing the worse prognosis or is merely a marker of more severe cardiac disease. Previous intervention studies with subcutaneous (s.c.) beta-EPO in combination with iron have either been uncontrolled or case-controlled studies. We report a randomized, double-blind, placebo-controlled study of the combination of s.c. EPO and oral iron versus oral iron alone in patients with anemia and resistant CHF. ⋯ In anemic CHF patients, correction of anemia with EPO and oral iron leads to improvement in New York Heart Association status, measured exercise endurance, oxygen use during exercise, renal function and plasma B-type natriuretic peptide levels and reduces the need for hospitalization.
