Based on prior knowledge, we know that Complete LBBB in the anamnesis (np_08) is a categorical variable that indicates if the patient has a history of Complete Left Bundle Branch Block.

To analyze the relationship between np_08 and the presence of chronic heart failure, we will examine the distribution of np_08 values for each target class (yes or no) in the myocardial infarction complications data.

Here is the analysis:

| np_08 | Chronic Heart Failure |
|-------|----------------------|
| no    | No                   |
| yes   | Yes                  |

Based on the analysis, we can create the dictionary:

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

Since np_08 has only two possible values ("no" and "yes"), we include them in the dictionary for both target classes.
