Synopsis

Four-dimensional flow magnetic resonance imaging (4D-flow MRI) technique has been developed to assess intra-cavity left ventricular (LV) blood flow. Hypertensive heart disease (HHD) is a common cardiovascular disease and manifested as left ventricular hypertrophy and diastolic/systolic dysfunction. The purpose of this study was to investigate whether 4D-flow CMR kinetic energy (KE) parameters are sensitive to distinguish HHD patients from age/gender-matched healthy controls, and to access if there are significant differences in different sub-groups of LV ejection fraction. We also aimed to investigate the association of LV KE to LV function parameters and LV mass.
