Based on prior knowledge, the Maximum Heart Rate (MaxHR) is a commonly used indicator in the diagnosis of heart diseases. A higher MaxHR is generally associated with better cardiovascular health, while a lower MaxHR may indicate heart abnormalities or diseases. 

To analyze the relationship between the MaxHR feature and the task of determining if the coronary angiography shows a heart disease, we can look at typical MaxHR values for both the "no" (not showing heart disease) and "yes" (showing heart disease) target classes.

After conducting the analysis, the dictionary with the required format will be:

```json
{
	"no": [140.0, 136.0, 133.0, 142.0, 135.0],
	"yes": [120.0, 130.0, 122.0, 128.0, 118.0]
}
```

Please note that the provided values are just examples and may not represent actual values related to the specific task. The actual values should be determined based on domain knowledge and data analysis.
