Based on the given feature description, we want to analyze the relationship between the feature "lat_im" and the presence of chronic heart failure in a patient with myocardial infarction complications.

To analyze this relationship, we can look at the different categories of the "lat_im" feature and how they relate to the presence or absence of chronic heart failure.

From the given feature description, the categories of the "lat_im" feature are as follows:
- QRS has no changes
- there is no infarct in this location
- QRS is like Qr-complex
- QRS is like QS-complex
- QRS is like QR-complex

Since we are trying to determine if the patient has chronic heart failure or not, we need to examine the relationship between each category of the "lat_im" feature and the presence or absence of chronic heart failure.

Based on prior knowledge, it is possible that the presence of certain types of QRS complexes (such as a QR-complex) in the lateral leads of the ECG could indicate chronic heart failure. However, for the other categories of the "lat_im" feature, it is not clear how they might be related to chronic heart failure.

Given this analysis, the dictionary representing the relationship between the "lat_im" feature and chronic heart failure is as follows:

```json
{
	"no": ["there is no infarct in this location"],  
	"yes": ["QRS is like QR-complex"]  
}
```

Please note that we only include the categories that have a clear relationship with chronic heart failure. If there are other categories of the "lat_im" feature that are hard to predict or irrelevant to the task, we exclude them from the dictionary.
