在经历了十年的斑点效应后，这项技术似乎即将加入一组革命性的创新，这些创新改变了我们使用超声心动图的方式。全球纵向应变(GLS)现在已被推荐为癌症治疗相关心脏功能障碍风险患者的一种随访手段(1)。然而，尽管GLS的使用已经普及，但许多临床医生对数据采集的实际过程并不熟悉，继续依赖射血分数。本IPIX的目的是通过说明它在美国最常用的设备中的应用，为不熟悉手中的患者提供GLS的获取和测量。根据不同厂家的软件(图1至图4)，从斑点跟踪得到的GLS略有不同，但有5个统一的步骤：1)视图选择；2)收缩末期定义；3)跟踪；4)评估跟踪质量；5)集成。分析步骤需要最少的时间和经验，但需要遵循--不应将菌株用作“黑匣子”。GLS是一个简单的参数，用百分比表示纵向缩短，由所有现代应变软件计算得出。有许多方法可以显示应变的不同方面，包括波形(以显示多个节段的收缩延迟和时间离散)和参数显示(显示整个心脏周期的空间离散)。这些显示对于评估区域压力很有价值。它们也用于测试亚临床左心功能障碍的质量控制--在这种情况下，应变在时间和空间上的分散都有些不寻常，它们的存在应该对可能存在的伪影的存在发出警报。
AFTER A DECADE OF SPECKLE STRAIN, THE TECHNIQUE SEEMS SET TO JOIN A GROUP OF TRANSFORMATIVE innovations that have changed how we use echocardiography. Global longitudinal strain (GLS) has now been recommended as a means of follow-up for patients at risk of cancer therapeutic–related cardiac dysfunction (1). However, although the use of GLS has spread, many clinicians are unfamiliar with the practical process of data acquisition and continue to rely on ejection fraction. The purpose of this iPIX is to facilitate the acquisition and measurement of GLS for following patients in unfamiliar hands by illustrating its application with the most commonly used equipment in the United States.Strain is analyzed by post-processing of apical views (Table 1). The derivation of GLS from speckle tracking is slightly different with the software of different manufacturers (Figures 1 to 4), but there are 5 unifying steps: 1) view selection; 2) definition of end systole; 3) tracing; 4) assessing tracking quality; and 5) integration. The analysis steps require minimal time and experience, but need to be followed—strain should not be used as a “black box.” GLS is a simple parameter that expresses longitudinal shortening as a percentage and is calculated from all modern strain software. There are a number of ways of displaying different aspects of strain, including waveforms (to illustrate contraction delay and temporal dispersion in multiple segments) and parametric displays (which illustrate spatial dispersion throughout the cardiac cycle). These displays are of value for the assessment of regional strain. They are also of use in the quality control of testing subclinical LV dysfunction—where both temporal and spatial dispersion of strain are somewhat unusual and their presence should provide an alert to the presence of possible artifact.
