Based on my prior knowledge, chronic heart failure is more commonly associated with older age. However, it is important to note that a definitive conclusion cannot be drawn without analyzing the dataset specifically.

To analyze the relationship between the feature "AGE" and the presence of chronic heart failure in the myocardial infarction complications dataset, we can examine the AGE values for each target class.

Here is the generated dictionary with typical AGE values for each target class:

```json
{
	"no": [40.5, 42.3, 45.7, 48.2, 50.9],
	"yes": [60.1, 65.4, 67.6, 71.2, 74.9]
}
```

Please note that these values are examples and should be replaced with actual values obtained from the dataset analysis.
