【摘要】 为评价超声心动图对扩张性心肌病（ＤＣＭ）患者左室舒张功能的诊断价值。方法：用超声心动图 和放射性核素显像（ＲＮＶ）对２０例ＤＣＭ患者和２０例同龄正常人的左室舒张功能进行对照分析。结果：ＤＣＭ组左室 舒张功能ＲＮＶ指标峰充盈率（ＰＦＲ）明显降低，同对照组比较差异有显著性（Ｐ＜０．０５）；超声指标二尖瓣血流频谱早 期充盈峰速度（νＥ）、晚期充盈峰速度（νＡ）、νＡ／νＥ等参数同对照组比较无明显差异（Ｐ＞０．０５），表现为“正常”。结 论：超声心动图舒张功能指标νＥ、νＡ、νＡ／νＥ不能真实反映ＤＣＭ患者的左室舒张功能。更多还原

【Abstract】 Aim:To evaluate the diagnostic value of left ventricular diastolic function in patients with DCM by echocardiography.Methods:Indexes of left ventricular diastolic function in 20 DCM patients and 20 normal subjects were measured by echocardiography and radionuclide ventriculography(RNY).Results:RNV index (Peak filling rate ,PFR)in DCM was significantlydecreased compared with that of control group(P<0.05).Echocardiography indexes(νE,νA,νA/E) DCM group and control group.Conclusion:ECchocardiography indexes(νE.νA.νA/νE)and’t really reflect the left ventricular diastolic function in patients with DCM.更多还原
