- W2355867495 abstract "Objective To investigate the feasibility,accuracy and reproducibility of real-time tri-plane echocardiography (RT-3PE) for measuring the global left ventricular systolic function in patients with myocardial infarction.Methods In the total of 30 patients with myocardial infarction, left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left ventricular ejection fraction(LVEF)were measured through RT-3PE and two-dimensional echocardiography(2DE)bi-plane Simpson’s method.The measured values were compared with those obtained through SPECT. Intra-and interobserver reliabilities were also assessed for the measurement of RT-3PE. Results (1)The values of LVEDV measured through RT-3PE and 2DE Simpson’s method were(86.67±37.64)ml and(86.43±38.25)ml respectively,and those of LVESV were(42.13±37.42)ml and(41.06±32.47 )ml respectively.While the values of LVEDV and LVESV measured by SPECT were(108.70±66.27)ml and(55.90±61.68)ml respectively.There were significant differences between the values measured by SPECT and RT-3PE,and also between those measured by SPECT and 2DE Simpson’s method(t=3.63,2.76,3.37,2.54,P0.01 or0.05);There was no significant difference among the values of LVEF measured by the three ways.(2)For the measurementof LVEDV,LVESV and LVEF,there was correlation between RT-3PE and SPECT(r respectively:0.943,0.965,0.816,P0.01),as well as between 2DE Simpson's method and SPECT(r respectively:0.896,0.957,0.721,P0.01).Altman-Bland analysis showed a good consistency between RT-3PE and SPECT in the measurement of left ventricular volume and systolic function.(3)There was no significant difference between the measurements obtained by the same or different examiners with RT-3PE(P0.05),and there was a good correlation for both intra-(r respectively:0.968,0.984,0.883,P0.01)and interobserver(r respectively:0.948,0.970,0.899,P0.01).Conclusions RT-3PE is a quick and accurate ultrasonic technology for the measurement of global left ventricular systolic function in patients with myocardial infarction" @default.
