Cardiogenic shock still has a high mortality. In order to correctly manage these patients, it is useful to have available haemodynamic parameters, invasive and non-invasive. The aim of this review is to show the current evidence on the use of echocardiographic aortic flow assessment by left ventricular outflow tract - velocity time integral.
Publications relevant to the discussion of echocardiographic aortic flow assessment by left ventricular outflow tract - velocity time integral and cardiogenic shock, were retrieved from PubMed®.
Left ventricular outflow tract - velocity time integral is an easily sampled and reproducible parameter that has already been shown to have prognostic value in various cardiovascular pathologies, including myocardial infarction and heart failure. Although there are still few data available in the literature, the LVOT-VTI also seems to have an important role in CS from prognosis to guidance in the escalation/de-escalation of vasoactive therapy and to support devices by allowing an estimate of patient's probability of response to fluid administration.
Aortic flow assessment can become a very useful invasive parameter in the management of cardiogenic shock.
心源性休克的死亡率仍然很高。为了正确管理这些患者，获得血流动力学的参数（有创和无创的）是很有用的。本文的目的是展示目前关于使用左心室流出道-速度时间积分评估超声心动图主动脉血流的证据。
从 PubMed® 中检索到与左心室流出道-速度时间积分和心源性休克的超声心动图主动脉血流评估相关的文献。
左心室流出道-速度时间积分是一个容易采样和可重复的参数，它已经在各种心血管疾病中显示出具有预后价值，包括心肌梗死和心力衰竭。尽管文献中仍有很少的数据，但 LVOT-VTI 在 CS 中似乎也有重要的作用，从预后到指导血管活性药物的升级/降级治疗，以及通过允许估计患者对液体给药的反应概率来支持设备。
主动脉血流评估可以成为心源性休克管理中非常有用的有创参数。
