Hemodynamics play a crucial role in diagnosing and managing heart failure (HF) as diagnostic markers and therapeutic targets. In an era of declining physical examination skills and questions about the safety of invasive monitoring, quantitative, objective data provided by echo-Doppler measurements can function as a type of "echo Swan-Ganz catheter" as an important adjustment to traditional methods of hemodynamic assessment. Echocardiographic measures of right- and left-sided filling pressures, pulmonary vascular resistance, and cardiac output are possible in many (although not all) HF patients. Recent studies suggest these measurements can have an important role in clinical pathways treating patients admitted with decompensated HF. The availability of miniaturized echocardiographic devices with full echo-Doppler capability may make repeatable, noninvasive hemodynamic assessment readily available and cost-effective for patients in many clinical settings.
血流动力学作为诊断标志物和治疗靶点，在心力衰竭（HF）的诊断和管理中起着至关重要的作用。在体格检查技能下降以及对有创监测安全性存在质疑的时代，由超声多普勒测量提供的定量、客观数据可作为一种“超声漂浮导管”，对传统血流动力学评估方法进行重要调整。在许多（尽管不是所有）HF患者中，可以通过超声心动图测量左右心室充盈压、肺血管阻力和心输出量。最近的研究表明，这些测量在治疗失代偿性HF住院患者的临床路径中可能发挥重要作用。具有完整超声多普勒功能的小型化超声心动图设备的出现，可能使可重复的、无创血流动力学评估在许多临床环境中对患者来说变得容易获得且具有成本效益。
