Based on my prior knowledge, fibr_ter_03 represents whether the patient received Fibrinolytic therapy by Celiasum 3m IU. To analyze the relationship between this feature and the presence of chronic heart failure in myocardial infarction complications, we can examine the distribution of fibr_ter_03 values for both target classes.

Here is the dictionary detailing the relationship between the feature fibr_ter_03 and chronic heart failure:

```json
{
    "no": ["no"],
    "yes": ["yes"]
}
```

In this case, we have only categorized values for fibr_ter_03 as "no" and "yes". The absence of additional values in the dictionary implies that the presence of chronic heart failure does not seem to be influenced by the fibr_ter_03 feature.
