风湿性心脏瓣膜病患者心脏功能与肺功能关系的临床研究

The relationship of lung function and heart function of RHD patients in different period

目的探讨风湿性心脏病患者心脏功能与肺功能的相互关系，以指导临床治疗。方法对９８例风湿性心脏病患者术前、术后近期、术后远期的肺功能检查及运动前后血气检测，以及根据心脏功能级别、心胸比率大小进行临床对比。结果随心脏功能的降低、心胸比率的增大，肺功能损害逐渐加重，运动前动脉氧分压及血氧饱和度与心脏功能关系不大，而运动后氧分压多数较运动前降低，血氧饱和度改变不大。术后近期肺功能改善不明显，术后远期随心脏功能的改善，心脏的缩小，肺功能逐渐改善，但小气道阻塞及肺弥散功能、功能残气量改善较慢。结论心脏功能直接影响肺功能，两者呈正相关。

Objective To investigate the relationship of heart function and lung function in RHD patients. Methods We compared heart postorioranterior film,lung function test results, PaO2 and O2 Sat of blood gas analysis before and after motion before operation, early postoperation, late postoperation,according to heart function and cardiothoracic ratio in 98 RHD patients. ResultsT5BZWith worsening of heart function and enlargement of cardiothoracic ratio, lung function worsened too. PaO2 and O2 Sat did not change appearently.The lung function of early postoperation did not improve significantly.The lung function improved gradually with better heart function and shortening of heart in later postoperation.But small air way obstruction and diffuse function and function residue volume changed slowly. ConclusionsZHeart function affects the lung function directly. They were positively correlated.
