Brief Summary

Optimizing patient survival and organ utility is a constant struggle for the liver transplant community. Despite rigorous cardiovascular evaluation before liver transplantation cardiovascular events are one of the leading causes of post-transplant morbidity and mortality in both early and late post transplant periods. Poor performance on measures of cardiopulmonary fitness has been associated with worse outcomes in liver transplant candidates. The investigators seek to determine the feasibility of obtaining measures of cardiopulmonary performance in liver transplant candidates from standard cardiopulmonary exercise testing (CPET) and from a modified 3 minute step test and to determine whether the 3 minute step test is suitable for the assessment of cardiopulmonary fitness in a future outcome study.
