Analysis:

To analyze the relationship between the FK_STENOK feature and the presence of chronic heart failure, we can examine the distribution of FK_STENOK values among patients with and without chronic heart failure. 

The FK_STENOK feature 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 oxygen-rich blood. The functional class categorizes the severity of angina symptoms, with higher classes indicating more severe symptoms.

To determine if there is a relationship between FK_STENOK and chronic heart failure, we can compare the distribution of FK_STENOK values among patients with chronic heart failure (target class "yes") and without chronic heart failure (target class "no").

Solution:

Based on the analysis, here is the dictionary representing the relationship between the FK_STENOK feature and the presence of chronic heart failure:

```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."]
}
```

Note that all possible values of FK_STENOK are included for both target classes "yes" and "no".
