The sick-sinus syndrome in Africans.

abstract：BACKGROUND:Anemia in heart failure is both common and associated with worse symptoms and increased mortality. Several small randomized controlled trials (RCTs) have assessed erythropoiesis-stimulating agents (ESAs), but definitive evaluation and clinical guidance are required. We sought to systematically review the eff...
