NPPB and myocardial infarction: Despite differences in variables selection (current study: LASSO and random forest; Mehran’s model: forward stepwise selection), the current model includes some of the consistent predictors with Mehran’s model, such as age, hemoglobin levels, the maker of heart dysfunction (abnormal NT-proBNP), and the marker of myocardial infarction (cardiac TnI).
