Keyword:  风湿性心脏病肺功能;
Abstract: 目的:探讨风湿性心脏病(风心病)患者心功能损害对肺功能的影响,及单、双瓣患者肺功能的区别。方法:采用日本chest-25肺功能仪对80例风心病患者的肺功能进行了测定。结果:心功能Ⅳ级较心功能Ⅲ级患者其肺活量(VC)、用力肺活量(FVC)、1秒钟用力呼吸容积占用力肺活量比例(FEV1%)、最大呼氧中段流速(MMEF)、最大通气量(MVV)、肺-氧化碳弥散量(DLCO)均显著降低。而残气/肺总量(RV/TLC)、闭合气量(CV)显著增加。双瓣患者较单瓣患者的VC、VC%、FVC、FEV1%、MMEF、MMEF%、MVV、MVV%、DLCO、DLCO%均显著降低,而RV/TLC显著增加。结论:风心病患者随着瓣膜受损的增加及心功能的降低,其阻塞性通气功能障碍及弥散功能障碍亦进一步加重。
