摘要

主动脉搏动指数（API）（收缩压-舒张压/肺动脉毛细血管楔压[PCWP]）综合了心室输出量和左心室充盈压力。它提供了心室-动脉耦合的替代品，并且与失代偿性心力衰竭的先进治疗和结果的需要有关。然而，它在需要临时机械循环支持（tMCS）的心源性休克患者中的应用是有限的，并且需要有创测量PCWP。本病例系列评估了超声API作为多普勒超声心动图评估API的无创工具的概念，以及其在tMCS心源性休克患者中的可行性。

Noninvasive Echocardiographic Hemodynamics in Patients on Temporary Mechanical Circulatory Support: A Case Series.

The aortic pulsatility index (API) (systolic blood pressure-diastolic blood pressure/pulmonary capillary wedge pressure [PCWP]) integrates ventricular output with left ventricular (LV) filling pressures. It offers a surrogate for ventricular-arterial coupling and is associated with the need for advanced therapies and outcomes in decompensated heart failure. However, its use in patients in cardiogenic shock requiring temporary mechanical circulatory support (tMCS) is limited and requires invasive measurement of PCWP. This case series evaluates the concept of echo-API as a noninvasive tool to estimate API using Doppler echocardiography, and its feasibility in patients with cardiogenic shock on tMCS.
