Based on prior knowledge, we need to analyze the relationship between the feature 'IM_PG_P' and the presence of chronic heart failure in myocardial infarction complications.

To do this, we can look at the values of 'IM_PG_P' for patients with and without chronic heart failure. We will consider the possible values of 'IM_PG_P' for each target class.

For the target class 'no' (indicating no chronic heart failure), the possible values of 'IM_PG_P' could be:
- 'no': If there is no right ventricular myocardial infarction, it is less likely to indicate chronic heart failure.

For the target class 'yes' (indicating chronic heart failure), the possible values of 'IM_PG_P' could be:
- 'no': While the presence of right ventricular myocardial infarction is not a direct indication of chronic heart failure, it can be present in some cases.
- 'yes': If there is a right ventricular myocardial infarction, it may suggest a higher likelihood of chronic heart failure.

Based on this analysis, we can create the requested dictionary:

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

Please note that this is a hypothetical analysis based on prior knowledge and assumptions. It is always recommended to validate any findings with actual data and consult with domain experts for accurate conclusions.
