Based on prior knowledge, the resting electrocardiogram (ECG) results can provide insights into the presence of heart disease. Here's an analysis of the relationship between the RestingECG feature and the task of determining whether the patient's coronary angiography shows a heart disease:

- Normal (RestingECG = 'Normal'): This category typically indicates a healthy heart. It is more likely to be associated with a negative result (no heart disease) in the coronary angiography.

- ST-T wave abnormality (RestingECG = 'ST'): This category suggests an abnormality in the shape or pattern of the ST-T wave in the ECG. It can be indicative of ischemia or myocardial infarction. Patients with this abnormality may have a higher likelihood of showing heart disease in the coronary angiography.

- Left ventricular hypertrophy (RestingECG = 'LVH'): This category suggests an enlargement of the left ventricle of the heart. It can be associated with conditions such as hypertension or valvular heart disease. Patients with LVH may have an increased risk of heart disease in the coronary angiography.

Considering these relationships, let's create the dictionary:

```json
{
	"no": ["Normal"],
	"yes": ["ST", "LVH"]
}
```

In this case, patients with a RestingECG value of 'Normal' are more likely to have a negative result in the coronary angiography (no heart disease). However, patients with 'ST' or 'LVH' RestingECG values have a higher likelihood of showing heart disease (positive result) in the coronary angiography.
