Based on prior knowledge and medical literature, the relationship between age and chronic heart failure (CHF) can be analyzed. Generally, the risk of CHF increases with age, so it is expected that older patients have a higher likelihood of experiencing myocardial infarction complications showing chronic heart failure.

Here is the analysis and the dictionary based on this analysis:

```json
{
    "no": [45.0, 50.0, 55.0, 60.0, 65.0],
    "yes": [70.0, 75.0, 80.0, 85.0, 90.0]
}
```

For the "no" class, representing patients without chronic heart failure, we have selected typical ages of 45.0, 50.0, 55.0, 60.0, and 65.0.

For the "yes" class, representing patients with chronic heart failure, we have selected typical ages of 70.0, 75.0, 80.0, 85.0, and 90.0.

These values are just examples and can vary depending on the specific dataset and population being analyzed.
