Approximately 50% of patients with heart failure (HF) have a preserved ejection fraction (HFpEF), and the incidence of HFpEF is increasing relative to HF with reduced ejection fraction (HFrEF). Both types of HF are associated with reduced survival and increased risk for hospitalization. However, in contrast to HFrEF, there are no approved treatments specifically indicated for HFpEF, and current therapy is largely focused on management of symptoms and comorbidities. Diagnosis of HFpEF in the outpatient setting also presents unique challenges compared with HFrEF because of factors including a high burden of comorbidities in HFpEF and difficulties in distinguishing HFpEF from normal aging. Primary care providers (PCPs) play a pivotal role in the delivery of holistic, patient-centric care from diagnosis to management and palliative care. As the prevalence of HF continues to rise in an aging population, PCPs will need to play a greater role in HFpEF care. This article will review HFpEF etiology and pathophysiology, diagnostic workup, and management of symptoms and comorbidities, with a focus on the critical role of PCPs throughout the clinical course of HFpEF.
大约 50%的心衰(HF)患者射血分数保留(HFpEF),HFpEF 的发病率相对于射血分数降低的心衰(HFrEF)呈上升趋势。这两种类型的 HF 都与生存率降低和住院风险增加有关。然而,与 HFrEF 不同,目前尚无专门针对 HFpEF 的批准治疗方法,目前的治疗主要集中在症状和合并症的管理上。与 HFrEF 相比,HFpEF 在门诊环境中的诊断也存在独特的挑战,这是由于 HFpEF 中有较高的合并症负担,以及难以将 HFpEF 与正常衰老区分开来等因素所致。初级保健提供者(PCP)在从诊断到管理和姑息治疗的整体以患者为中心的护理中发挥着关键作用。随着老龄化人口中 HF 的患病率不断上升,PCP 将需要在 HFpEF 护理中发挥更大的作用。本文将回顾 HFpEF 的病因和病理生理学、诊断检查以及症状和合并症的管理,重点介绍 PCP 在 HFpEF 整个临床过程中的关键作用。
