Abstract:
Objective To discuss the risk factors and outcome of abnormal lung function in adult congenital heart disease .Meth‐ods 327 patients with adult congenital heart disease undergoinglung function testing between January ,2009 to December ,2011 in our hospital were enrolled .Accorded to the severity of lung dysfunction based on predicted values of forced vital capacity (FVC) ,pa‐tients were divided into 3 groups :group A(normal lung function ,predicted FVC >70% ) ,group B(mildly impaired lung function , predicted FVC 60% -70% ) ,group C(moderately to severely impaired lung function ,predicted FVC <60% ) ,all the patients were followed‐up to January in 2013 ,the baseline characteristics and outcome were recorded ,the associate factors of moderately to se‐verely impaired lung function in adult congenital heart disease were analyzed through Logistic regression analysis ,the risk factors of death in adult congenital heart disease were analyzed through Cox regression analysis ,and Kaplan‐Meier curve compared survival rate of patients in the 3 groups .Results Lung function was abnormal in 167 patients(51 .1% ) with adult congenital heart disease , in which moderately to severely impaired were 96 patients(29 .4% ) .BMI ,smoke and enlarged cardiothoracic ratio were independent associate factors of moderately to severely impaired lung function in adult congenital heart disease (P<0 .05) .NYHA Ⅲ - Ⅳ and moderate to severe impairment of lung function were independent predictors of death in adult congenital heart disease .There were significant difference of the survival rate between group A and group C ,group B and group C(P<0 .05) ,but it was not significantly different between group A and group B(P>0 .05) .Conclusion Lung function impairment is common in patients with adult congen‐ital heart disease ,and moderate to severe impairment of lung function seriously impact the outcome of the patients .
