The limited number of adverse events constrained the number of variables that could be included in the multivariable models (e.g. Tables 4 and 6); however, the associations between infarct core native T1 and a range of surrogate and clinical outcomes including adverse remodelling revealed by CMR, NT-proBNP, and the primary health outcome (all-cause death/heart failure), supports the adverse prognostic importance of infarct core native T1. Here, NPPB is linked to heart failure.
