Abstract
Introduction

Field tests are commonly used as complements of cardiopulmonary exercise test (CPET) to evaluate the functional exercise capacity. The aims of this study were to validate the one-minute sit-to-stand test (STST) in congenital heart disease (CHD) children and to evaluate the possibility of predicting the peakVO2 using the STST in this paediatric population.

Methods

Children (8- to 18-year-old) followed for a CHD and performing CPET were recruited prospectively. Concomitantly, they performed STST. The heart rate (HR), oxygen saturation (SpO2), muscular fatigue and dyspnoea were recorded before (t0), immediately after (t1) and 1min after the end of the STST (t2).

Results

We observed a poor but significant correlation between the STST and the peakVO2 (r=0.306; p=0.013). A significant difference between girls and boys were observed for peakVO2 (p<0.001), HR t0 (p=0.030), HR t1 (p=0.002) and HR t2 (p<0.001). The proposed model of prediction, including the number of STST, weight, height and age explains 37% of the predicted peakVO2 variance.

Conclusion

The STST can provide relevant data on physical capacity in children with CHD. When CPET cannot be performed, we therefore propose an alternative equation using the STST as a surrogate of peakVO2 in CHD children.
