Abstract:
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.
