From the given feature description, it is clear that the feature "nr_01" represents the presence or absence of premature atrial contractions in the patient's medical history. The task is to determine whether this patient has chronic heart failure based on the myocardial infarction complications data.

In order to analyze the relationship between the feature "nr_01" and the target variable (chronic heart failure), we need additional information about the variables that are relevant to chronic heart failure. Without this information, it is difficult to directly establish a relationship between "nr_01" and chronic heart failure.

However, for the purpose of creating the requested dictionary, we can assume that certain categories of premature atrial contractions might be linked to chronic heart failure. Based on this assumption, we can create the dictionary as follows:

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

In this case, we have considered only two possible values for the "nr_01" feature: "no" and "yes". It is important to note that this is a simplified analysis based on the assumption that chronic heart failure might be linked to premature atrial contractions. Further analysis with more information about the relevant variables is necessary to draw more precise conclusions.
