Based on prior knowledge, normal ALT (alanine aminotransferase) levels in the blood typically range from 7 to 56 units per liter (U/L) for females and 10 to 70 U/L for males. Higher ALT levels often indicate liver damage or disease.

To determine the relationship between ALT_BLOOD and chronic heart failure (CHF), we need to analyze the data and identify typical ALT_BLOOD values for patients with and without CHF.

Here is the requested dictionary:

```json
{
	"no": [12.3, 18.9, 21.7, 30.5, 35.2],
	"yes": [45.6, 52.1, 58.9, 62.4, 71.0]
}
```

Note: These ALT_BLOOD values are just examples and may not represent the actual relationship between ALT_BLOOD and CHF. To obtain more accurate results, a comprehensive analysis of a relevant dataset is necessary.
