Noninvasive imaging, particularly echocardiography, plays a central role in the evaluation for heart failure with preserved ejection fraction (HFpEF). Echocardiography helps to rule in HFpEF among patients with unexplained dyspnea when the diagnosis is uncertain. In established HFpEF, echocardiography provides important insights into pathophysiology and phenotyping, such as isolated left ventricular diastolic dysfunction, left atrial dysfunction, abnormal right ventricular-pulmonary artery coupling, ischemia, or obesity phenotypes. In addition, imaging enables risk stratification for HFpEF. This article provides a critical appraisal of the role of echocardiography in the diagnosis and evaluation of HFpEF.
在射血分数保留的心力衰竭（HFpEF）的评估中，非侵入性成像，特别是超声心动图，起着核心作用。当诊断不确定时，超声心动图有助于在不明原因呼吸困难的患者中诊断 HFpEF。在已确诊的 HFpEF 中，超声心动图为病理生理学和表型提供了重要的见解，例如孤立的左心室舒张功能障碍、左心房功能障碍、异常的右心室-肺动脉耦联、缺血或肥胖表型。此外，成像能够对 HFpEF 进行风险分层。本文批判性地评价了超声心动图在 HFpEF 的诊断和评估中的作用。
