Based on prior knowledge, we can analyze the relationship between the feature "K_SH_POST" and the target variable "chronic heart failure". 

To determine if the myocardial infarction complications data of this patient show chronic heart failure, we can look at the possible values of the feature "K_SH_POST" for each target class.

Here is the analysis of the relationship between the feature "K_SH_POST" and the target variable:

- If the target variable is "no" (indicating no chronic heart failure), the possible values of the feature "K_SH_POST" can be "no" or "yes". 
- If the target variable is "yes" (indicating chronic heart failure), the possible values of the feature "K_SH_POST" can be "yes".

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

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

This dictionary shows the possible values of the feature "K_SH_POST" for each target class.
