The main objective of the MET: Reevaluation for Perioperative Cardiac Risk (MET-REPAIR)–NT-proBNP substudy was to compare the discrimination for MACE of models including NT-proBNP and validated clinical scores (Revised Cardiac Risk Index [RCRI]13 and National Surgical Quality Improvement Program, Risk Calculator for Myocardial Infarction and Cardiac [NSQIP MICA],14 respectively) with models that included self-reported functional capacity and those clinical scores. Here, NPPB is linked to myocardial infarction.
