摘　　要：心脏效率(CE)是由热力学衍生的血流动力学变量,指完成心脏外功所消耗的能量占心脏活动消耗的总能量的百分比,可由压力-容积(P-V)环曲线得出,近年来的衍生指标也可由微创设备直接获得。研究显示CE在血流动力学治疗过程中动态改变,是良好的预测临床结局的因素,需引起临床重视。本文就CE在血流动力学治疗中的研究进展作一综述。Cardiac efficiency is a hemodynamic variable derived from thermodynamics.It refers to the percentage of energy consumed to complete cardiac external work to total energy consumed by cardiac activity.It can be obtained from P-V loop curve.In recent years,cardiac efficiency can also be derived directly from minimally invasive devices.Studies have shown that it can change dynamically during hemodynamic management,and it is a good predictor for prognosis,which requires clinical attention.This article reviews the research progress of cardiac efficiency in hemodynamic management.
