Overshoot of the Respiratory Exchange Ratio during Recovery from Maximal Exercise Testing in Young Patients with Congenital Heart Disease.

ABSTRACT:

Introduction

The overshoot of the respiratory exchange ratio (RER) after exercise is reduced in patients with heart failure.

Aim

The present study aimed to investigate the presence of this phenomenon in young patients with congenital heart disease (CHD), who generally present reduced cardiorespiratory fitness.

Methods

In this retrospective study, patients with CHD underwent a maximal cardiopulmonary exercise testing (CPET) assessing the RER recovery parameters: the RER at peak exercise, the maximum RER value reached during recovery, the magnitude of the RER overshoot and the linear slope of the RER increase after the end of the exercise.

Results

In total, 117 patients were included in this study. Of these, there were 24 healthy age-matched control subjects and
