Based on prior knowledge, exercise-induced angina (ExerciseAngina) is a symptom where a person experiences chest pain or discomfort during physical activity or exercise. It is often associated with underlying heart disease or coronary artery disease. 

To analyze the relationship between ExerciseAngina and the presence of heart disease indicated by coronary angiography, we can look at historical data or conduct a study where patients with different ExerciseAngina values undergo coronary angiography to determine the presence or absence of heart disease. 

Assuming we have historical data, let's say we have the following observations:

| ExerciseAngina | Coronary Angiography |
| -------------- | -------------------- |
| N              | No                   |
| Y              | Yes                  |
| N              | No                   |
| N              | No                   |
| Y              | Yes                  |
| N              | No                   |
| N              | Yes                  |
| Y              | Yes                  |
| Y              | Yes                  |

Based on this data, we can construct the following dictionary:

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

The dictionary shows that for patients who do not exhibit exercise-induced angina (ExerciseAngina = "N"), the majority of them (but not exclusively) do not have heart disease (Coronary Angiography = "No"). On the other hand, patients who experienced exercise-induced angina (ExerciseAngina = "Y") tend to have heart disease (Coronary Angiography = "Yes"), but there are instances where they do not as well.

Please note that this analysis is based on the provided data and it is essential to have a larger dataset for more accurate conclusions. The dictionary format provides a summary of the relationships between ExerciseAngina and the presence of heart disease indicated by coronary angiography.
