30例老年慢性肾功不全患者左室结构及功能的动态观察

Dynamic detection of cardiac structure and function in patients with chronic renal failure

本文以超声心动图观察了30例老年慢性肾功不全患者左心结构及功能的变化,平均随访13个月。结果发现:肾功不全早期左室肥厚发生率无明显增加,左室收缩功能正常但舒张功能减退。肾功不全晚期原有左室肥厚加重,收缩功能均受损,舒张功能进一步下降。

Pulsed doppler echocardiography was used to evaluate the changes of left ventricular structure and function in 30 patients with chronic renal failure (CRF). The left ventricular weight(LVWI) and systolic function showed no chenges as compared with the controls in the early stage of CRF. But the decrement of VE (peak early velocity) and the increase in VE/VA (peak late velocity) indicated the damage of the diastolic function. After 13-months follow up, the LVWI elavated significantly, while the VE diminished further. The ejection fraction(EF), shortening fraction(FS) and circumfrancial shortening velocity(mVcf)decreased patently as compared with those present before the follow-up. 47.7% of the patients showed left ventricular heart failure.
