Response of the Oxygen Uptake Efficiency Slope to Orthotopic Heart Transplantation: Lack of Correlation With Changes in Central Hemodynamic Parameters and Resting Lung Function

OUES improved significantly after HTx, but, similar to other exercise parameters, remained considerably impaired. The changes in OUES were highly correlated with the improvements in other exercise variables, but did not correlate with marked improvements in central hemodynamics or resting lung function.
