摘要

摘要: 左心室射血分数(left ventricular ejection fraction，LVEF)作为心力衰竭诊断、治疗决策及疗效评估的核心参数，无论是基础研究还是临床应用，其测值的准确性具有极其重要的作用与价值。超声心动图是无创性评估LVEF的首选工具，但在实际应用中，由于存在技术本身局限性、操作者经验与临床应用场景限制等多种原因，其测值极易产生误差，甚至是重大差误，从而导致错误的诊断、错误的决策和错误的结论。本文对LVEF测值误差的来源进行了分析，对其质控进行了讨论，并对其未来的发展进行了展望。随着多模态影像综合运用和AI技术的研究，LVEF测量标准化和规范化有望进一步改进与加强。

Abstract: Left ventricular ejection fraction (LVEF) is a core parameter in the diagnosis, treatment, and management of heart failure. Its measurement accuracy plays a critical role in both basic research and clinical practice. Echocardiography is the preferred tool for non-invasive assessment of LVEF. However, in real-world applications, various factors——including technical limitations, operator experience, and clinical context——can lead to measurement errors, some of which may be substantial. These errors can result in misdiagnosis, inappropriate treatment decisions, and incorrect conclusions. This review analyzes the sources of LVEF measurement errors, discusses quality control strategies, and explores future perspectives. With the advancement of multimodal imaging integration and artificial intelligence technologies, the standardization and normalization of LVEF measurement are expected to improve further.
