Based on the feature description, the feature "ritm_ecg_p_01" represents the ECG rhythm at the time of admission to the hospital. The categories for this feature are 'yes' and 'no', indicating whether the ECG rhythm is sinus with a heart rate between 60-90 or not.

To analyze the relationship between this feature and the presence of chronic heart failure, we can observe that:
- If the ECG rhythm at the time of admission is "yes" (sinus with a heart rate 60-90), it implies that the patient may not have chronic heart failure.
- If the ECG rhythm at the time of admission is "no" (not sinus with a heart rate 60-90), it indicates that the patient may have chronic heart failure.

Therefore, the feature "ritm_ecg_p_01" can help determine if the myocardial infarction complications data of the patient shows chronic heart failure.
