Abstract：
Noninvasive cardiac imaging by transthoracic echocardiography is among the first-line assessments in evaluation of heart failure patients with preserved ejection fraction (HFpEF). Although systolic function seems preserved by conventional measurers, important information is found through examination of the heart\'s hemodynamic profile through Doppler and novel echocardiographic measures. These measures aid in establishing the diagnosis of HFpEF and provide valuable prognostic information. Targets of interest include the left ventricle diastolic function, atrial structure and function, and right ventricular function including pulmonary pressures. Contemporary assessments of the hemodynamic profile attainable through echocardiography in HFpEF at rest are reviewed and future directions outlined.
摘要：
经胸超声心动图的无创心脏成像是评估射血分数保留（HFpEF）的心力衰竭患者的一线评估之一。尽管常规测量器似乎保留了收缩功能，通过多普勒和新颖的超声心动图检查心脏的血流动力学轮廓可以发现重要信息。这些措施有助于建立HFpEF的诊断并提供有价值的预后信息。感兴趣的目标包括左心室舒张功能，心房结构和功能，和右心室功能，包括肺动脉压。回顾了在休息时通过超声心动图对HFpEF可获得的血液动力学特征的当代评估，并概述了未来的方向。
