实时三维超声心动图容积-时间曲线评价心力衰竭患者左室舒张功能的研究

Evaluation of left ventricular diastolic function in patients with heart failure using volume-time curve by real-time three-dimen sional echocardiography

目的应用实时三维超声心动图(TR-3DE)容积-时间曲线(VTC)评价心力衰竭患者左室舒张功能。方法应用TR-3DE的左室VTC测量104例心力衰竭患者和74例正常人的左室峰值充盈率(PFR),并进行比较。结果心力衰竭患者的PFR明显小于正常对照组(P<0.001)。结论 TR-3DE VTC可以准确测量左室PFR,能评价心力衰竭患者左室舒张功能状况。

Objective To evaluate left ventricular diastolic function in patients with heart failure （HF） using volume-time curve （VTC） by real-time three-dimensional echocardiography （RT-3DE）. Methods The left ventricular peak filling rate （PFR） in 104 patients With HF and 74 Healthy volunteers using VTC by RT-3DE were measured and compared. Results PFR in patients with HF was significantly lower than the normal control subjects （ P d0.01）. Conclusion VTC of RT- 3DE can measure left ventricular PFR accurately, and evaluate left ventricular diastolic function in patients with HF.
