Cardiac magnetic resonance image-based classification of the risk of arrhythmias in post-myocardial infarction patients

作者:

Highlights:

• Cardiac magnetic resonance image-based features were used to distinguish post-myocardial infarction patients into high and low arrhythmic risk groups.

• Seventeen features describing the size, location and texture of the scarred myocardium were used in different classifiers.

• In Experiment 1, a systematic testing of features and their combinations was done.

• SMOTE, wrapper based feature selection, and nested cross-validation were used in Experiment 2.

• Experiments 1 and 2 gave an accuracy of 94.4% (AUC = 0.965) and 92.6% (AUC = 0.921), respectively.
