Myocardial work is an emerging tool in echocardiography that incorporates left ventricular afterload into global longitudinal strain analysis. Myocardial work correlates with myocardial oxygen consumption, and work efficiency can also be assessed. Myocardial work has been evaluated in a variety of clinical conditions to assess the added value of myocardial work compared to left ventricular ejection fraction and global longitudinal strain. This review showcases the current use of myocardial work in adult echocardiography and its possible role in cardiac pathologies.
心肌做功是超声心动图领域的一项新兴技术,它将左心室后负荷纳入到整体纵向应变分析中。心肌做功与心肌耗氧量相关,还可以评估做功效率。心肌做功已在多种临床情况下进行了评估,以评估与左心室射血分数和整体纵向应变相比,心肌做功的附加价值。本综述展示了心肌做功在成人超声心动图中的当前应用及其在心脏病理中的可能作用。
