探讨慢性肾功能不全患者的左心功能变化。方法 选择 3 0例无临床心衰症状的肾功能不全患者作为观察组 ,另选 3 0例健康体检者作为对照 ,应用心脏多普勒超声测定左心功能。结果 观察组的CI较对照组减低 ,Amax、Dmax、Emax Amax、Smax Dmax在两组间有明显差异 ,而SI、EF、FS则无显著差异。结论 无临床心衰症状的肾功能不全患者虽无收缩功能变化 ,但已存在左心舒张功能减退
To investigate the changes of left ventricular function in patients with chronic renal failure. Methods Thirty patients with renal insufficiency without clinical symptoms of heart failure were selected as the observation group and 30 healthy subjects were selected as the control. Left ventricular function was measured by Doppler echocardiography. Results CI in the observation group was lower than that in the control group. Amax, Dmax, Emax Amax and Smax Dmax were significantly different between the two groups, but there was no significant difference between SI, EF and FS. Conclusions Although there is no change in systolic function in patients with renal insufficiency without clinical heart failure, there is already a decrease in left ventricular diastolic dysfunction
