Based on prior knowledge, the feature "INF_ANAM" represents the quantity of myocardial infarctions in the patient's medical history. To analyze how this feature relates to the target variable of chronic heart failure, we can examine the possible values of "INF_ANAM" for each target class: "yes" and "no".

Here is the dictionary with the specific details:

```json
{
	"no": ["one", "zero", "two"],  
	"yes": ["three and more"]
}
```

Explanation: 
- The target class "no" includes patients with chronic heart failure that have experienced one, zero, or two myocardial infarctions in their medical history.
- The target class "yes" includes patients with chronic heart failure that have experienced three or more myocardial infarctions in their medical history.

Please note that the value "three and more" is used to represent three or more myocardial infarctions in the target class "yes".
