- W2383629633 abstract "Objective:Detection can evaluate objective parameters about left ventricular diastolic function(LVDF), study the detective rate of parameters, researching feasibility of clinical applications.Methods:There were 76 essential hypertension(EH) patients and 65 normal. Record and measure parameters, dimensions of cardiac chambers, spectra of transmitral, pulmonary vein,rate of flow propagation in LV in diastole RFP (using color-M-mode) were measured, and acoustic quantification system (AQ) was activated to display the area-time curves of LV or LA and Doppler tissue imaging (DTI) was used to measure the diastolic velocities of mitral annular. The patients were divided into 4 groups according to the transmitral spectra. Group Ⅰ: with normal spectra (2≥E/A1); Group Ⅱ :relaxation damaged (E/A 1 ); GroupⅢ: with pseudonormalized spectrum (E/A1); Group Ⅳ: with restricted type of spectra(E/A2) .Results:We concluded that parameters from transmitral spectra RFP, DTI: all have high detective rate in detecting left ventricular diastolic dysfunction and can be routinely used. In discrimination of pseudonormalized ones with RFP, PV, AQ, DTI all have great detective rate.Conclusions:Analysis of parameters can improve accuracy rate of LVDF combining the technology PV, RFP, AQ and DTI can discriminate of pseudonormalized ones." @default.
