Based on prior knowledge, we know that fibrinolytic therapy is a treatment option for myocardial infarction. Chronic heart failure is a potential complication that can occur after a myocardial infarction, but it is not directly related to the administration of fibrinolytic therapy. Therefore, it is difficult to predict the presence of chronic heart failure based solely on the feature fibr_ter_08.

To create the dictionary, we will take into account all possible values of fibr_ter_08 and their corresponding target classes. However, since the relationship is not clear, we may not have values for both target classes.

Here is the dictionary formatted as a markdown code snippet:

```json
{
  "no": ["no"], 
  "yes": ["yes"]
}
```

Please note that in this case, the possible values for fibr_ter_08 are simply "no" and "yes", but in more complex scenarios, you may have additional categories.
