摘　　要：左心室收缩功能评估对疾病诊断、治疗方案选择以及患者的个性化分层管理均具有重要作用,但是经典的评估指标左心室射血分数(left ventricular ejection fraction, LVEF)敏感性不足。第一阶段射血分数(first phase ejection fraction, EF1)是评估左心室早期收缩功能的新兴指标,已在多种疾病中进行研究并有望成为继心肌应变和心肌做功之后,又一重要的心脏功能评价参数。笔者将对EF1的临床研究进展进行综述。The assessment of left ventricular systolic function is vital for the diagnosis of disease,the selec-tion of therapeutic regimens,and the individualized stratified management of different patients.However,the sensitivity of the classical assessment index,left ventricular ejection fraction(LVEF),is insufficient.First phase ejection fraction(EF1)is an emerging index for assessing early left ventricular systolic function.It is expected to become another important parameter for evaluating cardiac function,alongside myocardial strain and myocardial work.This review summarizes the progress of clinical research on EF1.
