Based on prior knowledge, we can analyze the relationship between the feature "nr_08" (Ventricular paroxysmal tachycardia in the anamnesis) and the presence of chronic heart failure in a patient with myocardial infarction complications.

Considering that the target variable is the presence of chronic heart failure, we need to examine how the values of "nr_08" relate to this target.

The dictionary that summarizes the relationship between "nr_08" and the presence of chronic heart failure is as follows:

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

Since the feature "nr_08" represents the presence or absence of Ventricular paroxysmal tachycardia in the anamnesis, the value "no" indicates the absence of the condition, while the value "yes" indicates its presence.

Based on this analysis, we can see that if the patient has chronic heart failure, the value of "nr_08" would be "yes", indicating a history of Ventricular paroxysmal tachycardia. Conversely, if the patient does not have chronic heart failure, the value of "nr_08" would be "no", indicating an absence of Ventricular paroxysmal tachycardia.

Note: It is important to mention that if there are other possible values of "nr_08" that are hard to predict or do not exist, they do not need to be included in the dictionary, as long as each target class has at least one value in their respective list.
