Abstract
Patients with chronic kidney disease (CKD) have a high burden of mortality and cardiovascular morbidity. Additional strategies to modulate cardiovascular risk in this population are needed. Anaemia has been associated with adverse outcomes in CKD populations, and the ability to modify this parameter with the use of erythropoiesis-stimulating agents has been a topic of much debate. Data on the effects of anaemia correction on cardiovascular outcomes and survival in CKD have been both discordant and controversial. It is hoped that the ongoing Trial to Reduce cardiovascular Events with Aranesp Therapy (TREAT) will help to redress the current clinical gaps and the uncertainty over the optimal management of anaemia in patients with CKD and type 2 diabetes mellitus. Anaemia is also increasingly being recognized as an important comorbid condition in patients with symptomatic heart failure. The ongoing Reduction of Events with Darbepoetin alfa in Heart Failure (RED-HF(TM)) trial is designed to determine whether the treatment of anaemia improves outcomes in such patients.
