Based on the feature description, the feature "zab_leg_03" represents whether the patient has bronchial asthma in the anamnesis. In order to determine whether the patient has chronic heart failure, we need to analyze the relationship between "zab_leg_03" and the target variable "myocardial infarction complications data".

Since the target class is chronic heart failure, it is unlikely that the presence or absence of bronchial asthma in the anamnesis (zab_leg_03) will have a significant impact on the presence of chronic heart failure. Therefore, we can say that the values "no" and "yes" of "zab_leg_03" are not strongly correlated with chronic heart failure.

Given this analysis, the possible values of "zab_leg_03" for the target class "no" are ["no"] and the possible values of "zab_leg_03" for the target class "yes" are ["yes"].
