Based on my prior knowledge, the functional class of angina pectoris (FK_STENOK) can be a relevant factor in determining the presence of chronic heart failure (CHF) in patients with myocardial infarction complications. FK_STENOK represents the severity of angina pectoris symptoms experienced by the patient.

To analyze the relationship between FK_STENOK and the task (determining the presence of CHF), we need to examine how the different categories of FK_STENOK relate to CHF.

Below is the generated dictionary containing the possible values of FK_STENOK for each target class:

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

Please note that the dictionary includes the FK_STENOK values that are associated with each target class. The categories "there is no angina pectoris" are related to the "no" class. The categories "II FC", "IV FC", "I FC", and "III FC." are associated with the "yes" class.
