Objective To assess the clinical application value of vector flow mapping (VFM) in evaluation of left ventricular diastolic function in patients with mycardiol infarction (MI).Methods Fifty patients with MI were enrolled as patients group.Sixty healthy people were enrolled as control group.The quantitative parameters, including position of vortex, the number of laps, the half-value area (S), Diameter of half-value area of vortex(D), the maximum flow volume of vortex (Qmax), and vortex intensity (Qmax/S) were measured in the VFM imaging mode and vortex mode.Difference of the parameters was evaluated between two groups.Ea/Aa were derived via TDI.
