风湿性二尖瓣病变患者血流动力学的改变对左心功能影响

The Effects of Hemodynamic Changes in Patients Withg Rheumatic Mitral Valve Disease on Left Ventricular Performance

对５２例风湿性二尖瓣病变血流动力学和左心室功能参数测定，ＭＲ＋ＭＳ组血流动力学参数比较无显著差异（Ｐ＞０．０５）；而左心室功能测定值两组间比较有显著差异。将血流动力学参数与左心功能测定值对比分析，血流动力学异常改变与ＤＳ、Ｄｄ、ＥＤＶＩ、ＥＳＶＩ呈正相关，而与ＦＳ、ＣＩ、ＬＶＳＷＩ呈负相关。

The hemodynamic changes and left ventricular performence were determined in the patients with rheumatic mitral valve disease.The results showed that the hemodynamic changes in group I(MS+MR)had no significant difference compared with that of group Ⅱ(MR+MS)( P >0 05).It was shown that the hemodynamic data of the group I had significant difference( P <0 05)compared with that group Ⅱ and that hemodynamic changes of two groups had positive correlation with DS,Dd,EDVI,ESVI and negative correlation with FS,CI,LVSWI.The results suggested that hemodynamic changes had some effects of left ventricular performance.
