Benefit of 2D-strain surveillance in improving cardiovascular outcomes in cancer patients undergoing cardiotoxic chemotherapy

癌症幸存者很容易因化疗引起的心肌损伤而发生心力衰竭。目前对这个问题的检测是基于一种不能识别心功能微小变化的方法。心脏应变是一种新的心功能敏感指标，可预测心功能障碍和心衰。本研究旨在确定是否可以使用应变来分配导致心功能改善并最终与HF降低相关的治疗方法。

Cancer survivors are susceptible to heart failure (HF) caused by heart muscle damage from chemotherapy. The current testing for this problem is based on a measure that cannot identify minor changes of cardiac function. Cardiac strain is a sensitive new marker of cardiac function which is predictive of overt dysfunction & HF. This study seeks to identify whether strain can be used to assign treatments that lead to improved cardiac function and are eventually associated with a reduction in HF.
