Hypertension (HTN) is a major risk factor contributing to the global burden of disease.
This study aims to investigate the clinical significance of vector flow mapping (VFM) by observing and quantifying energy loss (EL) during different phases and in different left ventricle (LV) segments.
The result that in patients with essential hypertension, the segmental EL increased significantly in each phase of the cardiac cycle with the progression of the disease.
