T1 Mapping–derived Predictors of Cardiac Remodeling and Fibrosis in Athletes using Advanced Machine Learning Techniques

Native T1 and extracellular volume values increased in athletes with cardiac remodeling, which may reveal the relationship between cardiac remodeling and myocardial fibrosis. Early cardiac magnetic resonance imaging is performed to monitor athletes' native myocardial T1 and ECV values, assess their risk levels, and guide subsequent surge planning to reduce the risk of adverse cardiovascular events. A GBM model with better performance can predict adverse cardiovascular events based on T1 mapping parameters, and the prediction can be verified by tracking the subsequent athlete's status.
