Based on the feature description, FK_STENOK represents the functional class of angina pectoris in the last year. Angina pectoris is chest pain or discomfort that occurs when the heart muscle does not receive enough blood. It is an important symptom of coronary artery disease.

To determine if the patient has chronic heart failure, we need to analyze the relationship between FK_STENOK and chronic heart failure. However, it is not explicitly mentioned how chronic heart failure is represented in the dataset. We will assume that chronic heart failure is represented by a binary variable (yes or no).

Since there is no clarification on the correlation between FK_STENOK and chronic heart failure, we cannot make any strong predictions. However, we can speculate that higher functional class of angina pectoris (IV FC, III FC) might indicate a higher likelihood of chronic heart failure, as these classes signify more severe symptoms.

Based on this analysis, we can create a dictionary as follows:

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