Conclusion Hemodialysis treatment is effective in decreasing cardiac preload, increasing myocardial contractility and cardiac afterload, improving cardiac function.

结论血液透析有效降低心脏前负荷，增加心肌收缩力，改善心功能，同时也增加心脏后负荷。

Objective: To study on the changes of right cardiac afterload and right ventricle pumping function according to different operation ways after pulmonary resection by Doppler pulmonary flow spectrum.

目的：运用多普勒肺血流频谱，观察不同术式的肺切除后右心后负荷及泵功能的变化情况。
