Objectives: to determine the relationship between pre-discharge 6-minute walking test in acute heart failure patients and rehospitalization rate within 30 days Methods: A longitudinal study hospitalized heart failure patients Results: Among 65 heart failure patients enrolled in the study, mean 6-minute walking distance between rehospitalized within 30 days discharge group (n = 12) and non-rehospitalized within 30 days discharge group (n = 53) were significantly different (respectively 174.48 ± 73.19 and 226 ± 74.8 meters, p = 0.034).
