Based on prior knowledge, we can analyze the relationship between the feature nr_02 (Premature ventricular contractions in the anamnesis) and the presence of chronic heart failure as a myocardial infarction complication.

There is a possibility that the occurrence of premature ventricular contractions in the patient's medical history could indicate chronic heart failure as a complication of myocardial infarction. However, without further information or studies specific to this dataset, it is difficult to reliably predict the relationship.

To create the dictionary, we can consider including the possible values of nr_02 for the target class "no" and "yes". Here is an example of how the dictionary could look like:

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

Please note that this is a generic example, and the actual values may vary depending on the dataset's characteristics and the outcomes of the analysis.
