Based on the provided feature description, the feature ritm_ecg_p_07 has two possible values: "no" and "yes". If the ECG rhythm at the time of admission to the hospital is sinus with a heart rate above 90, the value of ritm_ecg_p_07 would be "yes". Otherwise, it would be "no".

Since the feature description doesn't provide any information that directly relates to chronic heart failure, it is not possible to make a prediction of whether the myocardial infarction complications data of the patient show chronic heart failure based solely on the ritm_ecg_p_07 feature.
