Myocardial deformation imaging (strain imaging) is a technique to directly quantify the extent of myocardial contractility and overcomes several of the limitations of ejection fraction. The application of the most commonly used strain imaging method; speckle-tracking echocardiography to patients with sepsis cardiomyopathy heralds an exciting development to the field. However; the body of evidence and knowledge on the utility, feasibility and prognostic value of left ventricular global longitudinal strain in sepsis cardiomyopathy is still evolving. We conducted a review of literature on utility of left ventricular global longitudinal strain in sepsis cardiomyopathy. We discuss the role of left ventricular global longitudinal strain in mortality prediction, utility and limitations of the technique in the context of sepsis cardiomyopathy.
心肌形变成像(应变成像)是一种直接量化心肌收缩程度的技术,克服了射血分数的一些局限性。将最常用的应变成像方法——斑点追踪超声心动图应用于脓毒症心肌病患者,为该领域带来了令人兴奋的进展。然而,关于左心室整体纵向应变在脓毒症心肌病中的效用、可行性和预后价值的证据和知识仍在不断发展。我们对有关左心室整体纵向应变在脓毒症心肌病中效用的文献进行了综述。我们讨论了左心室整体纵向应变在死亡率预测中的作用,以及该技术在脓毒症心肌病背景下的效用和局限性。
