Based on prior knowledge and the given feature and task, the feature "K_SH_POST" (Cardiogenic shock at the time of admission to intensive care unit) is a categorical variable with two possible values: "no" and "yes". The task is to determine if the myocardial infarction complications data of this patient show chronic heart failure.

To analyze the relationship between the feature "K_SH_POST" and the target variable (presence of chronic heart failure), we can look at the possible values of "K_SH_POST" for each target class.

For target class "no" (no chronic heart failure), the possible values of "K_SH_POST" can be:

- "no"

For target class "yes" (chronic heart failure), the possible values of "K_SH_POST" can be:

- "no"
- "yes"

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

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

Please note that we include all possible values of "K_SH_POST" for each target class.
