Based on prior knowledge, it is expected that the duration of arterial hypertension (DLIT_AG) may have an effect on the occurrence of chronic heart failure in myocardial infarction patients. However, without specific domain knowledge, it is difficult to make a precise prediction for each value of DLIT_AG. 

To analyze the relationship between DLIT_AG and chronic heart failure, we can examine the distribution of DLIT_AG categories among patients with and without chronic heart failure.

Here is the analysis and dictionary:

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

Based on the data, patients with chronic heart failure have DLIT_AG values of "more than 10 years", "6-10 years", "three years", "two years", "one year", "five years", and "four years". Patients without chronic heart failure have DLIT_AG values of "there was no arterial hypertension", "more than 10 years", "6-10 years", "three years", "two years", "one year", "five years", and "four years".
