A Study to Evaluate Cardiopulmonary Exercise Testing in Liver Transplant Candidates

Overview

About this study

The purpose of this study is to determine agreement between cardiopulmonary exercise testing and cardiac stress testing (SOC) for the identification of subclinical coronary artery disease in liver transplant candidates, to determine agreement between cardiopulmonary exercise testing and dobutamine stress echocardiogram (SOC) for the identification of cirrhotic cardiomyopathy in liver transplant candidates, and to determine agreement between peak oxygen consumption from cardiopulmonary exercise testing and the liver frailty index or the six-minute walk test (SOC), for the identification of frailty in liver transplant candidates.
