To analyze the relationship between the feature ALT_BLOOD and the target variable of chronic heart failure, we can look at the ALT_BLOOD values for patients with and without chronic heart failure.

Based on prior knowledge, let's assume that normal ALT_BLOOD values range from 5 to 40 units (U/L). Higher values indicate potential liver damage or disease.

To determine the relationship between ALT_BLOOD and chronic heart failure, we need to compare the ALT_BLOOD values for patients with chronic heart failure (target class 'yes') and those without it (target class 'no').

Here is the dictionary with typical ALT_BLOOD values for each target class:

```json
{
	"no": [10.5, 15.2, 20.1, 25.6, 30.3],
	"yes": [28.9, 32.7, 37.5, 42.1, 45.8]
}
```

Please note that the given values are just examples and may not represent actual data. Also, always consult with domain experts and refer to specific datasets or studies for more accurate and reliable information.
