Erythropoiesis-stimulating agents for anaemia in chronic heart failure patients
Abstract
BACKGROUND: Chronic heart failure (CHF) is a leading cause of morbidity and mortality worldwide. Anaemia is a common (12-55%) co-morbid condition and is associated with worsening symptoms and increased mortality. Anaemia is treatable and can be targeted in the treatment of patients with CHF. Erythropoiesis-stimulating agents (ESA), supplemented by iron therapy, are used to treat anaemia in chronic kidney disease and cancer, however safety concerns have been raised in these patients. The clinical benefit and safety of these agents in CHF remains unclear.
OBJECTIVES: To assess the benefits and risks of ESA for CHF patients with anaemia.
SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 3), MEDLINE (1950 to October 2008), EMBASE (1980 to October 2008) and reference lists of articles. No language restrictions were applied.
SELECTION CRITERIA: Randomised controlled trials of any ESA, with or without iron therapy, in CHF patients were eligible for inclusion.
DATA COLLECTION AND ANALYSIS: Three reviewers independently assessed study quality and extracted data. Original authors were contacted for additional information. The outcomes of interest were: exercise tolerance, haemoglobin level, New York Heart Association (NYHA) functional class, quality of life, left-ventricular ejection fraction, B-type natriuretic peptide, CHF-related hospitalisations, all-cause mortality and adverse effects. Risk ratios (RR) were…
