Clinical Trial Summary

The diagnosis of heart failure with preserved ejection fraction (HFpEF) is often complex. Echocardiography has the advantages of being a non-invasive, simple operation, low price, and high repeatability, and is of great value in the diagnosis of HFpEF. However, the current echocardiographic assessment of left ventricular diastolic dysfunction and elevated filling pressure is based on multi-parameter indirect judgment, and new parameters are urgently needed to achieve accurate judgment of left ventricular diastolic function and an accurate diagnosis of HFpEF. Myocardial stiffness refers to the ability of the myocardium to undergo stress and strain. It is an important part of the pathophysiology of cardiac diastolic dysfunction and an important parameter for clinical evaluation of the diastolic function of HFpEF. Shear-wave elastography is a novel ultrasound-based elastography technology. Based on the shear wave generated by the remote induction of the radiation force of the focused ultrasound beam, the hardness of myocardial tissue can be measured quantitatively, locally, and noninvasively, and the change in myocardial stiffness in patients with HFpEF can be directly reflected. Currently, no relevant studies have applied shear-wave elastography to the diagnosis of HFpEF. This study aims to identify changes in myocardial stiffness measured by shear-wave elastography in patients with HFpEF based on a multicenter study and apply myocardial stiffness parameters to the diagnosis of HFpEF.
