Analysis:

To analyze the relationship between the ALT_BLOOD feature and the presence of chronic heart failure in myocardial infarction complications data, we need to consider the normal range of ALT (alanine transaminase) levels in blood.

Normal ALT levels can vary slightly based on different medical reference ranges, but generally, the upper limit of normal (ULN) for ALT is considered to be around 40 IU/L (international units per liter) for adult men and 30 IU/L for adult women. Values above this normal range may indicate liver damage or disease.

Based on this prior knowledge, we can analyze the relationship of ALT_BLOOD with chronic heart failure as follows:

1. If the ALT_BLOOD value falls within the normal range or below, it is less likely to be associated with chronic heart failure. We can classify these values into the 'no' class.

2. If the ALT_BLOOD value is above the normal range, it may indicate liver damage or disease. Elevated ALT levels can result from conditions like hepatitis, alcohol abuse, fatty liver disease, or drug-induced liver injury. However, chronic heart failure itself may not directly cause elevated ALT levels. So, we can classify these values into the 'yes' class.

Based on this analysis, we can create the dictionary as follows:

```json
{
	"no": [10.0, 15.0, 20.0, 25.0, 35.0],
	"yes": [45.0, 50.0, 55.0, 60.0, 70.0]
}
```

In this dictionary, the 'no' class values represent ALT_BLOOD values within or below the normal range, while the 'yes' class values represent ALT_BLOOD values above the normal range, indicating potential liver damage or disease. Please note that these specific values are just examples and should not be considered definitive or exhaustive.
