Based on prior knowledge, we can analyze the relationship between the feature "FK_STENOK" and the target variable "chronic heart failure" in the myocardial infarction complications data.

The feature "FK_STENOK" represents the functional class of angina pectoris in the last year. Angina pectoris refers to chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. 

The categories of "FK_STENOK" are as follows:
- "There is no angina pectoris"
- "II FC" (Functional Class)
- "IV FC"
- "I FC"
- "III FC"

To determine if the patient has chronic heart failure or not, we need to analyze how the functional class of angina pectoris in the last year (FK_STENOK) is related to the presence of chronic heart failure.

To create the dictionary, we will categorize the values of "FK_STENOK" based on the target variable "chronic heart failure". 

Here is the dictionary with the possible values of "FK_STENOK" for each target class:

```json
{
  "no": ["there is no angina pectoris", "II FC", "IV FC", "I FC", "III FC."],
  "yes": ["there is no angina pectoris", "II FC", "IV FC", "I FC", "III FC."]
}
```

Please note that we have included all the possible values of "FK_STENOK" for both target classes. However, if certain values of "FK_STENOK" do not occur in the dataset for either target class, they will not be included in the dictionary.
