Peak oxygen uptake and metabolic equivalents explained by six-minute walk test: A prospective observational study in predicting heart failure patient readmission

•Functional capacity contributes to reducing cardiovascular events and re-hospitalization of patients with heart failure.•Conducting a 6-min walk test before patient discharge can help identify a patients' risk for readmission.•VO2max and METs can be utilized to create a comprehensive treatment flow for heart failure patients to prevent readmission.
