在34例正常或冠心病患者中,以2DE心尖四腔切面法与数字减影左室造影心功能测定比较;以PDE法测定二尖瓣舒张期e/a与导管法左室舒末压比较,评价了超声无创性测定左室舒、缩功能的可行性。结果显示,2DE法所测EDV、ESV、SV、EDVI、ESVI及EF值均与数字减影法接近,两者之间无显著区别;其中两法所测EF分别为0.61±0.15和0.66±0.14(p>0.05)相关性良好(γ=0.7382,n=28,p<0.01),
In 34 patients with normal or coronary heart disease, the 2DE apical four-chamber view was compared with the digital subtraction left ventricular angiography; the PDE was used to measure the mitral diastolic e / a and the catheterization of left ventricular end-diastolic pressure , Evaluate the feasibility of noninvasive ultrasound determination of left ventricular systolic and diastolic function. The results showed that the 2DE method measured EDV, ESV, SV, EDVI, ESVI and EF values are close to the digital subtraction method, no significant difference between the two; of which the EF measured by the two methods were 0.61 ± 0.15 and 0.66 ± 0.14 (p> 0.05), with good correlation (r = 0.7382, n = 28, p <0.01)
