Even with important advances in revascularization strategies and heart failure pharmacotherapies, venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been widely used to provide life support in patients with refractory cardiogenic shock and has significantly improved their survival rate [Lung computed tomography (CT) is regarded as the gold standard for noninvasive evaluation of pulmonary oedema, but it is not convenient for critically ill patients with cardiogenic shock undergoing VA-ECMO due to the exposure to ionizing radiation and the need for transportation, which limits its application [However, the application of bedside LUS in patients with cardiogenic shock undergoing VA-ECMO support has rarely been reported and has not been systematically studied. In this study, patients with cardiogenic shock who received VA-ECMO were reprospectively enrolled, and the LUS score was obtained before and during VA-ECMO support. The aim of this study was to assess the potential utility of the LUS score in patients receiving VA-ECMO support.
