Based on my prior knowledge, I will analyze the relationship between the feature SVT_POST and the presence of chronic heart failure.

Analysis:

To determine the relationship between SVT_POST and chronic heart failure, we need to analyze the values of SVT_POST for each target class (yes and no) in the myocardial infarction complications data.

Here is a breakdown of the feature SVT_POST based on the target class:

For patients with chronic heart failure (yes):

- It is possible that patients with chronic heart failure may have experienced paroxysms of supraventricular tachycardia at the time of admission to the intensive care unit (SVT_POST = yes).

For patients without chronic heart failure (no):

- It is possible that patients without chronic heart failure may not have experienced paroxysms of supraventricular tachycardia at the time of admission to the intensive care unit (SVT_POST = no).

Based on this analysis, we can construct the dictionary as follows:

```json
{
	"no": ["no"],
	"yes": ["yes"]
}
```

According to the analysis, chronic heart failure is possible when the value of SVT_POST is "yes". For patients without chronic heart failure, the value of SVT_POST is "no".

Note: Since it's not specified, we assume there are only two possible values for the SVT_POST feature - "yes" and "no".
