To analyze the relationship between the feature D_AD_ORIT (diastolic blood pressure according to intensive care unit) and the occurrence of chronic heart failure, we can proceed as follows:

1. We'll start by defining the appropriate ranges of values for diastolic blood pressure. Normal diastolic blood pressure readings usually range between 60-80 mmHg. Any reading above 90 mmHg may indicate hypertension or elevated blood pressure. However, it's important to note that the notation used for D_AD_ORIT is not provided, so we'll assume it's in mmHg.

2. We'll then analyze the feature by grouping the values of D_AD_ORIT for cases where chronic heart failure (CHF) is present ('yes') and where it is not present ('no').

3. Based on the analysis, we'll select 5 typical values for D_AD_ORIT for each target class ('no', 'yes').

Here's the dictionary formatted as a markdown code snippet:

```json
{
	"no": [70.5, 75.2, 77.8, 79.4, 82.1],
	"yes": [85.6, 89.9, 91.3, 94.7, 98.2]
}
```

Please note that the values provided above are just examples and may not reflect the actual relationship between D_AD_ORIT and chronic heart failure. Additional analysis and domain knowledge may be required.
