For more than 30 years, echocardiography, through the measurement of ejection fraction and wall motion assessment, has played a crucial role in the diagnosis and management of patients with acute and chronic ischemic heart disease. The introduction of myocardial strain, measured by speckle tracking echocardiography, is shifting this paradigm. Strain imaging catches something pathophysiologically deeper into myocardial function, facing a wide range of clinical applications. This review summarizes the basic concepts of strain imaging and its applicability in clinical practice for the evaluation of the ventricular and the left atrial function in ischemic cardiomyopathy.
三十多年来，超声心动图通过射血分数和壁运动评估的测量，在急性和慢性缺血性心脏病患者的诊断和管理中发挥了关键作用。心肌应变的引入，通过斑点追踪超声心动图来测量，正在改变这一模式。应变成像捕捉到了更深层次的心肌功能的病理生理学变化，具有广泛的临床应用。这篇综述总结了应变成像的基本概念及其在缺血性心肌病患者心室和左心房功能评估中的临床应用。
