"Machine Learning with a Heart" 's task purpose

HI
only one info:
this dataset is relatively simple; then this is only for “learning purpose”
or has an effective medical utility?

then this is a predictive task (to predict probability of heart injury)
or only to determine if there is an injury?

This is a “just for fun” competition for learners to practice their skills. It is not going to be used in a clinical setting.
