The latest guidelines of the European Society of Cardiology have proposed a classification of heart failure based on left ventricular ejection fraction. Three distinct groups have been identified: heart failure with ejection fraction ≥50%, between 40 and 49%, and <40%. This classification has the advantage to be simple but it has been criticized because it is not clear whether the mid-range ejection fraction group is an independent category or just a transition phase between the other two groups. The purpose of this article is to discuss the characteristics and prognosis of mid-range ejection fraction heart failure on the basis of current evidence.
欧洲心脏病学会的最新指南提出了一种基于左心室射血分数的心力衰竭分类方法。已确定三个不同的组：射血分数≥50%、40%至49%以及<40%的心力衰竭。这种分类方法的优点是简单，但也受到了批评，因为尚不清楚射血分数中等范围组是一个独立类别还是仅仅是其他两组之间的过渡阶段。本文的目的是根据现有证据讨论射血分数中等范围心力衰竭的特征和预后。
