摘要
E/e'是超声心动图多普勒组织成像(DTI)技术的衍生指标,源于传统二尖瓣血流图与多普勒组织运动速度曲线图(DT-PW)。该指标因无创、简便、高敏感度,越来越受到国内外学者广泛关注。其临床应用范围广泛,包括心肌收缩、舒张功能及左室充盈压的评估等,此外还提供了重要的预后信息。本综述阐述了该指标的基本概念及测量方法 ,并讨论其主要临床应用以及存在的局限性和发展前景。
E/e’ is a derivative index of echocardiography Doppler tissue imaging（DTI） technology,which is derived from the ratio of early diastolic mitral inflow velocity（E） to early diastolic TDI annular velocityle’s（E/e’ ）.Giving the index’s noninvasive,convenient,and of high sensitivity,more and more attentions have been paid to it.Its clinical applications are very wide,including the evaluation of systolic and diastolic myocardium and estimation of left ventricular filling pressure.In addition, it also provides important prognostic informations.This review explained the principle concept of E/e’ index and the new measurement method,discussed the main clinical application,and noted the limitations of the index and the development prospects.
