Based on prior knowledge and domain expertise, there is a relationship between the feature "GB" (Presence of essential hypertension) and the occurrence of chronic heart failure in patients with myocardial infarction complications. Essential hypertension is a chronic condition characterized by high blood pressure, and it can contribute to the development and progression of chronic heart failure.

To create the dictionary, we need to analyze the relationship between the feature "GB" and the target variable "chronic heart failure" in the myocardial infarction complications data of the patient.

Here is the dictionary with the analysis results:

```json
{
	"no": ["there is no essential hypertension"],
	"yes": ["Stage 2", "Stage 3", "Stage 1"]
}
```

Explanation:
- For the target class "no" (patients without chronic heart failure), the only possible value for the feature "GB" is "there is no essential hypertension".
- For the target class "yes" (patients with chronic heart failure), the possible values for the feature "GB" are "Stage 2", "Stage 3", and "Stage 1". These stages indicate the severity of essential hypertension, which can contribute to the development of chronic heart failure.

Please note that the exact values for the feature "GB" may vary depending on the dataset and the context. This analysis assumes a categorical variable with the mentioned categories.
