Abstract：Objective To evaluate the cardiorespiratory exercise tolerance of children with acyanotic congenitalheart disease（CHD）. Methods Relevant clinical data of 175 children aged 4 -18 years with acyanotic CHD（CHDgroup）were collected. The children’s height, weight, body mass index（BMI）and other growth and development indicators and the results of cardiorespiratory exercise tolerance assessed by the six-minute walk test（6MWT）were retrospectively analyzed, with 377 age-and sex-matched healthy children as the normal control group（NCgroup）. Results The 6 MWTresults showed that the average walking distance（520.0m）in the CHD group was significantly shorter than that in the NCgroup（590.0m）（P<0.001）. In both groups, the heart rate, breath frequency, blood pressure, and blood oxygen saturation were all within the normal range pre-and post-test, and the children’s physiological response to exercise was also within the normal range. No adverse events occurred. The growth and development indexes of the CHD group were significantly lowerthan those of the NC group（Pheight=0.022, Pweight=0.002, PBMI=0.003）. Conclusion The 6 MWT is a reliable test which can be used as a practical tool for assessing the cardiorespiratory exercise tolerance of children with acyanotic CHD, and also this population have lower cardiorespiratory exercise tolerance than healthy children.
