Children and adolescents with CHD have lower VO2max and HR compared to controls
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 .
Results of exercise testing at a mean age of 10 years after neonatal arterial switch operation
Aim : This prospect i ve follow‐up study investigated long‐term exercise capacity at a mean age of 10 y after neonatal arterial switch operation for transposition of the great arteries in a large group of homogeneous unselected children . Methods : 56 asymptomatic children , aged 7.9–14.3 y ( 10.5 ± 1.6 , mean ± SD ) , were examined with respect to exercise tolerance , electrocardiographic ( ECG ) response and activity of biochemical markers for myocardial injury . The protocol included st and ard electrocardiography , M‐mode and two‐dimensional echocardiography at rest , a Bruce walking treadmill test to voluntary exhaustion , and determination of cardiac troponin I and T , creatine kinase and myoglobin from venous blood sample s at rest and 4 h after exercise . Heart rate , blood‐pressure response to exercise stress and endurance time were compared with published results of age‐matched normal children . Results : 54 patients ( 96.4 % ) had normal exercise capacity ; a reduction in 2 patients was not due to cardiac disease . Heart rate and systolic blood pressure rose significantly between rest and peak exercise and did not differ from normal controls , whereas diastolic blood pressure was lower . ECG remained normal at rest and on exercise in 54 children ( 96.4 % ) . Serum values of cardiac troponin I and T , creatine kinase and myoglobin were normal at rest and after exercise in all patients
