Based on prior knowledge, there may be a relationship between gender and chronic heart failure. Research suggests that certain risk factors, such as hypertension, diabetes, and smoking, are associated with both chronic heart failure and myocardial infarction.

To analyze the relationship between gender and chronic heart failure, we need to examine the data on myocardial infarction complications and check if there is an association between gender and the presence of chronic heart failure.

Here's the dictionary based on the analysis:

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

This dictionary suggests that both males and females can have chronic heart failure, as it includes both genders in both the "no" and "yes" categories.
