Based on prior knowledge, it is generally known that chronic heart failure can be a complication of myocardial infarction. However, the relationship between the feature STENOK_AN and chronic heart failure is not explicitly stated. 

To analyze the relationship, we can examine the categories of the feature and try to infer any potential connections with chronic heart failure.

```json
{
	"no": ["never", "during the last year", "more than 5 years ago"],
	"yes": ["4-5 years ago", "one year ago", "two years ago", "three years ago"]
}
```

In the absence of any specific information about the correlation between STENOK_AN and chronic heart failure, we can consider the following assumptions:

- Categories such as "never," "during the last year," and "more than 5 years ago" might indicate a lower likelihood of chronic heart failure.
- Categories such as "4-5 years ago," "one year ago," "two years ago," and "three years ago" might suggest a higher likelihood of chronic heart failure.

By categorizing the feature values into "no" and "yes" based on these assumptions, we can create the dictionary as shown above.
