My prior knowledge suggests that the feature "fibr_ter_07" represents the administration of fibrinolytic therapy using a drug called Celiasum 250k IU. Fibrinolytic therapy is commonly used for the treatment of acute myocardial infarction, also known as a heart attack. Therefore, the feature "fibr_ter_07" is likely to be related to the target variable of chronic heart failure, as myocardial infarction can lead to long-term heart damage and subsequent heart failure.

To analyze the relationship between "fibr_ter_07" and chronic heart failure, we need to examine how the values of "fibr_ter_07" are distributed among patients with and without chronic heart failure.

Here is the dictionary with the specific details:

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

Based on the analysis, patients without chronic heart failure ("no") only have one possible value of "fibr_ter_07," which is "no" indicating that they did not receive Celiasum 250k IU fibrinolytic therapy. On the other hand, patients with chronic heart failure ("yes") can have either "no" or "yes" as the value of "fibr_ter_07," indicating whether they received or did not receive the therapy.

Please note that it is assumed that the values "no" and "yes" represent the absence or presence of fibrinolytic therapy with Celiasum 250k IU, respectively. If there are other possible values for this feature, they should be included in the respective lists in the dictionary.
