The effect of elevated heart rate (HR) on morbidity and mortality is evident in chronic stable heart failure; data in this regard in acute decompensated heart failure (ADHF) setting are scarce. In this single-centre study, we sought to address the prognostic value of HR and beta-blocker dosage at discharge on all-cause mortality among patients with heart failure and reduced ejection fraction and ADHF.

出院时心率对射血分数降低心力衰竭急性失代偿的预后价值

在慢性稳定性心力衰竭中，心率升高 (HR) 对发病率和死亡率的影响很明显；急性失代偿性心力衰竭（ADHF）情况下这方面的数据很少。在这项单中心研究中，我们试图探讨 HR 和出院时 β 受体阻滞剂剂量对心力衰竭、射血分数降低和 ADHF 患者全因死亡率的预后价值。
