This article focuses on the recent findings in the diagnosis and treatment of diastolic heart failure (DHF) or heart failure with preserved ejection fraction.
DHF has become the most common form of heart failure in the population. Although diastolic dysfunction still plays a central role, it is now understood that DHF is a very complex clinical entity with heterogeneous pathophysiology and significant contribution from extracardiac comorbidities. Alterations in ventricular-arterial coupling play a significant role in the impaired hemodynamic response to exercise seen in these patients. The absence of diastolic dysfunction at rest does not exclude the diagnosis of DHF. There has been little to no progress made in identifying evidence-based, effective, and specific treatments for patients with DHF. This may be because of the pathophysiological heterogeneity, incomplete understanding of DHF, and heterogeneity of patients included in clinical trials with variable inclusion criteria.
The understanding of the phenotypic heterogeneity and multifactorial pathophysiology of DHF may lead to novel therapeutic targets in the future. Currently, the key to the treatment of DHF is aggressive management of contributing factors.
本文重点关注舒张性心力衰竭(DHF)或射血分数保留的心力衰竭在诊断和治疗方面的最新研究成果。
DHF已成为人群中最常见的心力衰竭形式。尽管舒张功能障碍仍起着核心作用,但现在人们认识到,DHF是一个非常复杂的临床实体,其病理生理学具有异质性,且心外合并症有重大影响。心室-动脉耦合的改变在这些患者运动时受损的血流动力学反应中起重要作用。静息时无舒张功能障碍并不能排除DHF的诊断。在确定针对DHF患者的循证、有效且特异性的治疗方法方面进展甚微或几乎没有进展。这可能是由于病理生理异质性、对DHF的理解不完整以及纳入标准各异的临床试验中患者的异质性。
对DHF表型异质性和多因素病理生理学的理解可能会在未来带来新的治疗靶点。目前,治疗DHF的关键是积极处理相关因素。
