title: [The relationship of lung function and heart function of RHD patients in different period].
abstract: OBJECTIVE
  To investigate the relationship of heart function and lung function in RHD patients.
  
  
  METHODS
  We compared heart posterior-anterior film, lung function test results, PaO(2) and O(2) 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.
  
  
  RESULTS
  With worsening of heart function and enlargement of cardiothoracic ratio, lung function worsened too. PaO(2) and O(2) Sat did not change apparently. 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.
  
  
  CONCLUSIONS
  Heart function affects the lung function directly. They were positively correlated.
