Abstract
Background
Children and adolescents with congenital heart disease often have alterations
in their exercise capacity that can be evaluated by various functional
testing.
Objective
To evaluate the functional capacity of children and adolescents with
congenital heart disease (CHD) with systematic review and meta-analyses.
Methods
The review included observational studies, data from the first evaluation of
randomized clinical trials or observational follow-up periods after clinical
trials which evaluated functional capacity by cardiopulmonary exercise test,
stress testing, six-minute walk test or step test, in children and
adolescents with CHD, aged between six and 18 years, and comparisons with
healthy controls in the same age group. The quantitative assessment was
performed by meta-analysis, by comparing the maximal oxygen consumption
(VO2max) of children and adolescents with CHD and respective
control groups.
Results
Twenty-five of 2.683 studies identified in the search met the inclusion
criteria. The VO2max measurement showed that patients with CHD
have a decrease of 9.31 ml/Kg/min (95% CI. -12.48 to -6.13; I2,
94.3%, P for heterogeneity < 0.001) compared with the control group. The
meta-analysis of the data of maximum heart rate (HR) reached during
cardiopulmonary test and stress testing, retrieved from 18 studies, showed a
HR value of -15.14 bpm (95% CI. -20.97 to -9.31; I2, 94.3%, P for
heterogeneity < 0.001) compared with the control group.
Conclusion
Children and adolescents with CHD have lower VO2max and HR
compared to controls.
