This review focuses on a new method for noninvasive, complex evaluation of left ventricular (LV) systolic function using an echocardiography-based technology of computing indexes of myocardial performance by construction of pressure-deformation curves. Since this new method accounts for the effect of afterload on myocardial contractility, the article presents data demonstrating advantages of the evaluation of LV myocardial performance over the speckle-tracking echocardiography and other methods in diagnostics of several diseases. The review provides a description of this method and its advantages and limitations. The authors analyzed results of major studies on evaluation of LV performance. Prospects of implementation and practical use of the method are discussed in the aspects of diagnostics of cardiovascular diseases and risk stratification for different groups of patients.
本综述聚焦于一种基于超声心动图技术的新方法，该方法通过构建压力-变形曲线来计算心肌性能指标，从而对左心室（LV）收缩功能进行无创、综合评估。由于这种新方法考虑了后负荷对心肌收缩力的影响，本文展示的数据表明，在几种疾病的诊断中，评估左心室心肌性能相较于斑点追踪超声心动图及其他方法具有优势。本综述对该方法及其优缺点进行了描述。作者分析了评估左心室性能的主要研究结果。从心血管疾病诊断及不同患者群体风险分层的角度，探讨了该方法的实施前景和实际应用。
