摘　　要：目的 :观察新的肺静脉血流图指标评价左室舒张功能 (L VEDP)的准确性。方法 :6 0例心血管疾病患者先后行超声心动图和心导管检查 ,记录肺静脉血流图 ,多导生理记录仪记录左室舒张末压。结果 :S/D时间比值与 L VEDP呈正相关 (r=0 .85 3,P<0 .0 1) ;D/AR时间比值与 L VEDP呈负相关 (r=- 0 .6 6 4 ,P<0 .0 1) ;S/D波幅比值与 L VEDP呈负相关 (r=- 0 .4 2 1,P<0 .0 1) ;D/AR比值与 L VEDP呈负相关 (r=- 0 .5 18,P<0 .0 1) ;AR波幅与 L VEDP呈正相关 (r=0 .5 0 5 ,P<0 .0 1) ;AR波时间与 L VEDP呈正相关 (r=0 .32 4 ,P<0 .0 5 )。 S/AR时间比值、A/AR时间比值、 S/AR比值与 L VEDP相关性无统计学意义。结论 :新的肺静脉血流图指标 - S/D时间比值、D/AR时间比值以及 D/AR比值能准确反映左室舒张功能 ;S/AR时间比值、Objective:To observe the accuracy of estimating of left ventricular function with pulmonary venous velocities.Methods:Sixty patients with cardiovascular diseases received echocardiography and cardiac catheterization.Pulmonary venous velocities were recorded,Left ventricular end diastolic pressure(LVEDP)was recorded with poly lead physiologic recorder.Results:There were positive correlations:S/D time,AR wave,AR time to LVEDP,( r =0 833, P <0 01),( r =0 506, P <0 01)and ( r =0 324, P <0 05)respectively.There were negative correlations:D/AR time ratio,S/D ratio,D/AR ratio to LVEDP,( r =-0 664, P <0 01),( r =-0 421, P <0 01),and ( r =-0 518, P <0 01)respectively.LVEDP had no significant correlation with S/AR time ratio,A/AR time ratio and S/AR ratio.Conclusions:New pulmonary venous velocities indexes,S/D time ratio,D/AR time ratio,and D/AR ratio can accurately estimate the left ventricular function,but S/AR time ratio and S/AR ratio can not accurately estimate the left ventricular function.
