Based on prior knowledge, we can analyze the relationship between the feature "endocr_02" (Obesity in the anamnesis) and the task of identifying chronic heart failure complications in the patient's myocardial infarction data.

It is reasonable to assume that obesity might be a risk factor for chronic heart failure. Therefore, we can hypothesize that patients with a history of obesity (endocr_02 = "yes") are more likely to show chronic heart failure complications compared to patients without a history of obesity (endocr_02 = "no").

Based on this analysis, we can create a dictionary as follows:

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

In this case, since the only possible values for the "endocr_02" feature are "no" and "yes", we include both values in the respective lists for each target class.
