Based on prior knowledge and understanding of the feature fibr_ter_02 and the task of determining if the myocardial infarction complications data of a patient shows chronic heart failure, we can analyze the relationship between the feature and the target as follows:

Since fibr_ter_02 represents whether or not the patient received fibrinolytic therapy by Celiasum 1m IU, we can consider it as a potential indicator of the treatment received by the patient. To determine if there is a relationship between fibr_ter_02 and chronic heart failure, we can analyze the frequencies of the different values of fibr_ter_02 for each target class.

Here is the analysis and the corresponding dictionary:

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

Explanation:
- In the "no" class, both "no" and "yes" values are present for fibr_ter_02, indicating that some patients who did not receive fibrinolytic therapy also did not show chronic heart failure, while some patients who did receive fibrinolytic therapy also did not show chronic heart failure.
- In the "yes" class, only the "yes" value is present for fibr_ter_02, indicating that all patients who showed chronic heart failure received fibrinolytic therapy.

Please note that this analysis assumes a simple relationship between the feature fibr_ter_02 and the target variable. Further analysis and statistical testing may be required to establish a stronger relationship between the two variables.
