Recovery of left ventricular function after insertion of left ventricular assist device: evaluation of echocardiographic parameters and longitudinal analysis

在一些严重心力衰竭的患者中，插入机械泵来辅助心脏实际上导致心脏功能的恢复。需要对这一过程有更多的了解，这样我们才能更好地预测和识别它。本项目旨在评估超声（超声心动图）在测量机械泵患者心脏功能方面的有用性。一旦确定其有效性，我们将使用它来评估并尝试诱导此类患者的康复。

In some patients with severe heart failure, insertion of a mechanical pump to assist the heart actually leads to recovery of the heart's function. More understanding of this process is needed so we can better predict and identify it.This project aims to assess the usefulness of ultrasound (echocardiography) in measuring heart function in patients who have a mechanical pump. Once its usefulness is established, we will use it to evaluate and attempt to induce recovery in such patients.
