Introduction: Liver transplantation (TxF) is a complex procedure and considered standard treatment for patients with terminal chronic liver disease, many of them suffering from severe organic deterioration. The CTP Pugh scores (CTP) and Model for End-stage Liver Disease (MELD) have been used to assess the severity of liver disease and the risk of death, respectively. The st Six Minutes Walk Test (6MWT) assesses the functional capacity of these patients. Objective: Our goal was to determine whether there is a correlation between the 6MWT and the CTP and MELD scores in candidates for TxF. Methods: Cross-sectional study of cirrhotic patients undergoing pre-transplant evaluation in a follow-up at the Liver Transplantation United of Hospital de Base, São José do Rio Preto SP, from May 2012 to may 2014 All of them submitted to 6MWT consecutively. The results of the 6MWT and CTP and MELD scores were analyzed by the Student’s t tests and Spearman. Results: We studied 45 men and 11 women with a mean age 54.50 ± 11 years, who walked mean distance of 461.35 ± 87,31m in the 6MWT. It has been found that patients with CTP B and C walked distance significantly shorter when compared with the predicted value (p <0.0001) and with patients presenting CTP score A (p <0.016). There was significant inverse correlation between the 6MWT and the scores CTP (p = 0.01) and native Meld (p value = 0.05). Conclusion: There was inverse correlation between the 6MWT test and the Child and MELD scores. The 6MWT lower values identified patients on the waiting list for liver transplantation, higher Chid carriers (uncompensated) and highest MELD (worse prognosis). This data have strenghthened the potential usefulness of the 6MWT to evaluate the severity and prognosis of these patients.
