Anemia is common in heart failure patients but its prevalence varies widely according to various sources. There is no agreement regarding the definition of anemia to be used and several risk factors have been found to be associated with higher prevalence of anemia in heart failure patients. The prevalence of anemia depends on its definition and the clinical characteristics of the patients included in the studies. Anemia is associated with adverse prognosis in the general population, in patients with end-stage renal disease, chronic diseases, coronary artery disease and also in patients with heart failure; however, despite all the information available, the issue of whether anemia is an independent predictor of mortality and the nature of the risk between anemia and mortality in heart failure patients are not yet fully understood.
贫血在心力衰竭患者中很常见，但其患病率因各种来源而异。关于所使用的贫血定义尚无共识，并且已发现多种危险因素与心力衰竭患者贫血的较高患病率相关。贫血的患病率取决于其定义以及研究中纳入患者的临床特征。贫血与普通人群、终末期肾病患者、慢性病患者、冠状动脉疾病患者以及心力衰竭患者的不良预后相关；然而，尽管有所有这些可用信息，但贫血是否是死亡率的独立预测因素以及心力衰竭患者贫血与死亡率之间风险的性质尚未完全了解。
