风湿性心脏病患者肺功能的异常改变

Abnormal changes of pulmonary function in rheumatic heart disease

目的观察风湿性心脏病(简称风心病)患者早期肺水肿的肺功能的改变。方法对18例风心病患者和18例正常对照组成人分别进行肺功能测定。两组受检者均无慢性肺部疾病和吸烟史。结果18例风心病患者RV/TLC%,△N2%0.5和Ⅲ相斜率明显高于18例正常对照组,P<0.01,差异有显著性;FEV1.0%及V50/HT低于对照组,P<0.05。结论肺功能测定对风心病患者肺功能受损程度和发现早期肺水肿提供敏感的指标。

To disclose the abnormal changes of pulmonary function in rheumatic heart disease with early pulmonary edema. Pulmonary function were measured in 18 patients with rheumatic heart disease and 18 normal subjects. The two groups were all without chronic pulmonary diseases and smoking history. The mean values of pulmonary function (RV/TLC%,△N2%0.5 and Ⅲ phase shope ) of rheumatic heart disease were significantly higher than those of 18 normal subjects(all P<0.01). The mean values of FEV1.0% and V50/HT were lower than those of normal subjects. [Conclusion] The results indicate to measure pulmonary function will provide sensitive guidelines for distinguishing the impairing level of lung and early pulmonary edema in rheumatic heart disease.
