Based on the given feature "fibr_ter_08" and the task of determining whether the patient shows chronic heart failure or not, we can analyze the relationship between the feature and the target by examining the values of "fibr_ter_08" for each target class.

Here is the analysis:

- If the target class is "no" (indicating no chronic heart failure), possible values of "fibr_ter_08" could be:
  - "no"
  
- If the target class is "yes" (indicating chronic heart failure), possible values of "fibr_ter_08" could be:
  - "yes"

Based on this analysis, the dictionary will be:

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