Based on the given feature "inf_im" and the task of determining whether the myocardial infarction complications data of this patient show chronic heart failure, we can analyze the relationship between the feature and target by examining the possible values of "inf_im" for each target class.

Here is the analysis and the resulting dictionary:

```json
{
	"no": ["there is no infarct in this location"], 
	"yes": ["QRS is like Qr-complex", "QRS is like QR-complex", "QRS has no changes"]
}
```

Explanation:
- For the target class "no," the only possible value of "inf_im" is "there is no infarct in this location."
- For the target class "yes," the possible values of "inf_im" are "QRS is like Qr-complex," "QRS is like QR-complex," and "QRS has no changes."

Please note that we excluded the values that are hard to predict from the dictionary, as instructed. Also, this analysis is based on prior knowledge and may vary depending on the specific dataset and context.
