Abstract

ABSTRACT Accurate evaluation of cardiac function has become increasingly important as the treatment of cardiac disease has become more complex. At the same time, technological advances allow greater accuracy and precision in cardiac measurements. Measurement of left ventricular ejection fraction (LVEF) has been a pillar of cardiac evaluation. Several noninvasive modalities are available to assess LVEF; each has advantages and limitations. This review examines various modalities used to measure LVEF and focuses on the relative strengths and weaknesses of each modality. In some clinical settings, however, LVEF may be too insensitive to convey subtle changes in LV contractility. In certain clinical situations, use of LVEF may be an insufficient measure of left ventricular systolic function. Global longitudinal strain is one such parameter that has shown promise for detecting subtle reductions in left ventricular contractility in subjects with chemotherapy-induced cardiotoxicity.
左心室射血分数:对一个旧参数的新见解
摘要随着心脏病的治疗变得越来越复杂,准确评估心脏功能变得越来越重要。与此同时,技术进步使心脏测量具有更高的准确性和精确度。左心室射血分数(LVEF)的测量一直是心脏评估的支柱。有几种非侵入性模式可用于评估LVEF;每一种都有优点和局限性。本综述考察了用于测量LVEF的各种模式,并重点介绍了每种模式的相对优势和劣势。然而,在某些临床环境中,左心室射血分数可能过于敏感,无法传达左心室收缩力的细微变化。在某些临床情况下,LVEF的使用可能不足以衡量左心室收缩功能。整体纵向应变就是这样一个参数,它有望检测化疗诱导的心脏毒性受试者左心室收缩力的细微降低。
