Based on prior knowledge, the angina pectoris functional class (FK_STENOK) may have a relationship with chronic heart failure. Higher functional class values may be associated with a higher likelihood of chronic heart failure.

To analyze the relationship between FK_STENOK and chronic heart failure, we need to examine the distribution of FK_STENOK values for both the "yes" and "no" classes of chronic heart failure.

For the "yes" class (chronic heart failure present), we can check the cases where patients have chronic heart failure and find the corresponding FK_STENOK values. This will help us identify the possible values of FK_STENOK for chronic heart failure.

For the "no" class (chronic heart failure not present), we can check the cases where patients do not have chronic heart failure and their FK_STENOK values. This will help us identify the possible values of FK_STENOK for no chronic heart failure.

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

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

This dictionary suggests that patients with chronic heart failure can have FK_STENOK values of "II FC", "IV FC", "I FC", or "III FC.", while patients without chronic heart failure have the value "there is no angina pectoris".
