ACCORDING TO THE EJECTION FRACTION, PATIENTS WITH HEART FAILURE MAY BE DIVIDED INTO TWO DIFFERENT GROUPS: heart failure with preserved or reduced ejection fraction. In recent years, accumulating studies showed that increased mortality and morbidity rates of these two groups are nearly equal. More importantly, despite decline in mortality after treatment in regard to current guideline in patients with heart failure with reduced ejection fraction, there are still no trials resulting in improved outcome in patients with heart failure with preserved ejection fraction so far. Thus, novel pathophysiological mechanisms are under development, and other new viewpoints, such as multiple comorbidities resulting in increased non-cardiac deaths in patients with heart failure and preserved ejection fraction, were presented recently. In this review, we will focus on the tested as well as the promising therapeutic options that are currently studied in patients with heart failure with preserved ejection fraction, along with a brief discussion of pathophysiological mechanisms and diagnostic options that are helpful to increase our understanding of novel therapeutic strategies.
根据射血分数,心力衰竭患者可分为两个不同的组:射血分数保留或降低的心力衰竭。近年来,越来越多的研究表明,这两组患者的死亡率和发病率增加情况几乎相同。更重要的是,尽管射血分数降低的心力衰竭患者按照当前指南治疗后死亡率有所下降,但迄今为止,尚无试验能改善射血分数保留的心力衰竭患者的预后。因此,新的病理生理机制正在研究中,最近还提出了其他新观点,例如多种合并症导致射血分数保留的心力衰竭患者非心脏性死亡增加。在本综述中,我们将重点关注目前正在射血分数保留的心力衰竭患者中研究的经过试验验证以及有前景的治疗选择,并简要讨论有助于增进我们对新治疗策略理解的病理生理机制和诊断方法。
