Doppler echocardiography is the corner-stone of non-invasive investigation of patients with a clinical diagnosis of heart failure. It provides an accurate and quantitative assessment of cardiac structure and function. Furthermore, spectral Doppler measurement is an invaluable technique for estimating intracardiac pressures with their crucial value in the optimum management of heart failure patients, irrespective of ejection fraction. Speckle tracking echocardiography stretches the unique application of echocardiography to analyze the myocardial deformation function which has proved very accurate in detecting ischemia, dyssynchrony, subclinical dysfunction and also in estimating pulmonary capillary wedge pressures. The role of longitudinal myocardial left atrial deformation dynamics has recently emerged as a valuable tool for assessing left ventricular diastolic dysfunction in patients with cardiac diseases regardless of their ejection fraction. Finally, the extent of myocardial deformation has been shown to correlate with the severity of myocardial fibrosis, a common finding in patients with heart failure.
多普勒超声心动图是对临床诊断为心力衰竭患者进行无创检查的基石。它能对心脏结构和功能进行准确且定量的评估。此外，频谱多普勒测量是一项非常重要的技术，可用于估计心腔内压力，这对于心力衰竭患者的最佳管理具有关键价值，无论其射血分数如何。斑点追踪超声心动图拓展了超声心动图的独特应用，用于分析心肌变形功能，该功能在检测心肌缺血、不同步、亚临床功能障碍以及估计肺毛细血管楔压方面已被证明非常准确。纵向心肌左心房变形动力学的作用最近已成为评估心脏病患者左心室舒张功能障碍的一项有价值的工具，无论其射血分数如何。最后，心肌变形程度已被证明与心肌纤维化的严重程度相关，心肌纤维化在心力衰竭患者中很常见。
