101例腹膜透析患者心功能评价及意义

目的探讨心脏彩超检查在腹膜透析（PD）患者心功能评价的作用及意义。方法选择101例住院的持续非卧床腹膜透析（CAPD组）患者及30例正常人（对照组）为研究对象，应用心脏彩超测定CAPD患者及对照组左心房内径（LAD）、左室舒张末期内径（LVDd）、左室收缩末期内径（LVDs）、室间隔厚度（IVST）、肺动脉压力（PAP）及舒张早期和舒张晚期二尖瓣口最大血流速度之比（E／A）等，计算左心室质量指数（LVMI）。结果CAPD组LAD、LVDd、LvDs、IVST、PAP、及LVMI高于对照组（P〈0．05），E／A低于对照组（P〈0．05）；相关性分析显示CAPD组LVEF与BNP呈负相关（r=-0．467，P=0．000）；LVMI与BNP（r=0．416，P=0．006）旱正相关。结论心脏彩超可用于CAPD患者心脏结构和功能的评估。

Role of echocardiography in evaluation of cardiac function in peritoneal dialysis patients

Objective To analyze the cardiac function value and the clinical application evaluation of echocardiography in peritoneal dialysis （PD） patients. Methods Left atrial diameter （ LAD）, left ventricular end diastolic diameter （ LVDd）, left ventricular end systolic diameter （LVDs）, interventricular septal thickness （IVST）, interventricular septal thickness （PAP）, left ventricle weight index （LVMI） early and late wave of mitral valve flow （E/A） were determined by echocardiography in 101 patients with continuous ambulatory peritoneal dialysis （CAPD） and 30 normal persons （ control group）. Results Echocardiography showed that LAD, LVDd, LVDs, IVST, PAP, LVMI of CAPD group were higher than those of the control group （P 〈 0.05 ）, while E/A was lower than that of the control group （ P 〈 0.05 ）.Correlation analysis showed that LVEF was negatively correlated with BNP （ r = - 0. 467, P = 0. 000 ） ; LVMI was positively correlated with BNP （r = 0.416,P = 0. 006）. Conclusion Echocardiography can accurately evaluate the cardiac function, which is worth further clinical research.
