摘要目的 探讨支气管哮喘患儿病程长短对右心功能的影响以及哮喘控制后右心功能的转归.方法 利用彩色多普勒超声诊断仪对36例病程>1年缓解期哮喘患儿和38例病程≤1年缓解期哮喘患儿进行右心功能测定,并进行组间比较.结果 支气管哮喘患儿病程>1年右心收缩功能受损,病程≤1年患儿右心收缩功能指标均正常,哮喘病程>1年者经过规范化维持治疗后右心室功能指标有改善.结论 儿童支气管哮喘病程长短对右心功能有影响,经过规范化治疗,这种心功能受损现象呈可逆性.

abstractsObjective To explore the cardiac function of right ventricles in children with various course of bronchial asthma. Methods The cardiac function was evaluated by using the Doppler echocardiography in 36 chil-dren with course > 1 year bronchial asthma in remission stage and 38 children with course ≤ 1 year bronchial asthma in remission stage. 40 healthy children were used as normal controls. After treatment, 10 children with course > 1 year were evaluated again. Results The injury of right ventricle systolic function was predominant in children with > 1 year bronchial asthma, The systolic function of right ventricle remained normal in children with ≤ 1 year bronchi-al asthma. Conclusion The cardiac function damage occurs in children with > 1 year bronchial asthma and will be recoveied by cure the astham. The Doppler echocardiography is noninvasive method for determination of cardiac func-tion.
