Based on prior knowledge, we can analyze the relationship between the feature "nr_08" (Ventricular paroxysmal tachycardia in the anamnesis) and the task of determining whether the myocardial infarction complications data of this patient show chronic heart failure.

In order to analyze this relationship, we need to examine the distribution of the feature values for each target class (chronic heart failure - yes or no).

Possible values of feature "nr_08" and their relationship with the target:

- If feature "nr_08" is "no", it suggests that there is no Ventricular paroxysmal tachycardia in the anamnesis.

- If feature "nr_08" is "yes", it suggests that there is Ventricular paroxysmal tachycardia in the anamnesis.

Based on this analysis, we can create a dictionary with the following format:

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

The dictionary signifies that if the feature "nr_08" has a value of "no", it is indicative of chronic heart failure not being present. On the other hand, if the feature "nr_08" has a value of "yes", it suggests that chronic heart failure may be present.

Note: It is crucial to verify the accuracy of this analysis with domain-specific knowledge and to validate the relationship between the feature and target using appropriate statistical or machine learning techniques.
