Based on prior knowledge, we can assume that a fasting blood sugar (FastingBS) value greater than 120 mg/dl indicates an abnormal result. 

To analyze the relationship between FastingBS and the presence of heart disease, we can examine the FastingBS values for patients with and without heart disease.

Here is the analysis and the resulting dictionary:

```json
{
	"no": [90.5, 98.3, 101.2, 102.9, 115.7],
	"yes": [130.8, 140.2, 150.6, 165.1, 180.3]
}
```

These values are just examples and should be interpreted in the context of the specific dataset being analyzed. The "no" list contains FastingBS values for patients without heart disease, while the "yes" list contains values for patients with heart disease.

Please note that the provided values are not exhaustive and should not be considered as a complete representation of the relationship between FastingBS and heart disease. They are only meant to illustrate typical values for each target class.
