Based on prior knowledge, there could be a relationship between the duration of arterial hypertension (DLIT_AG) and the presence of chronic heart failure in the patient. Arterial hypertension is a risk factor for developing chronic heart failure. Therefore, it is plausible that patients with longer durations of arterial hypertension may have a higher likelihood of experiencing chronic heart failure.

To generate the dictionary, we need to examine the relationship between DLIT_AG and the presence or absence of chronic heart failure for each category of DLIT_AG.

Possible values for DLIT_AG are:
- 'there was no arterial hypertension'
- 'more than 10 years'
- '6-10 years'
- 'three years'
- 'two years'
- 'one year'
- 'five years'
- 'four years'

We will analyze the myocardial infarction complications data for each DLIT_AG category and determine whether chronic heart failure is present or not. Then we will populate the dictionary accordingly.

Based on the analysis, the generated dictionary will look like:

```json
{
	"no": ["there was no arterial hypertension"],
	"yes": ["more than 10 years", "6-10 years", "three years", "two years", "one year", "five years", "four years"]
}
```

Please note that the value "there was no arterial hypertension" is included in the "no" category, as it indicates the absence of arterial hypertension. The other DLIT_AG categories are included in the "yes" category, as they suggest a duration of arterial hypertension, which may contribute to chronic heart failure.
