Resumo

Introdução: Pacientes com insuficiência renal crônica (IRC) submetidos à hemodiálise, frequentemente, desenvolvem complicações cardiopulmonares e musculoesqueléticas que afetam diretamente a sua capacidade funcional cardiorrespiratória. Objetivo: Analisar a capacidade funcional cardiorrespiratória com o teste de caminhada de 6 minutos (TC6min) em pacientes com IRC em tratamento dialítico. Método: 20 indivíduos (10 homens) participaram do estudo. A capacidade funcional cardiorrespiratória foi avaliada por meio do TC6min. Foi utilizada a estatística descritiva, para mostrar a média e o desvio padrão das variáveis do grupo. Os dados foram analisados pelo teste t de Student pareado, comparando os valores obtidos do TC6min com os valores preditos pela equação de Iwama et al. 2009. Resultado: Houve diferença significativa nos valores da distância percorrida obtidos no TC6min, quando comparados com os valores preditos por Iwama et al. 2009. Conclusão: A pesquisa constatou uma redução significante na capacidade funcional cardiorrespiratória em pacientes com IRC dialítica.

Abstract

Introduction: Patients with chronic renal failure undergoing hemodialysis often develop cardiopulmonary and musculoskeletal complications that directly affect their cardiopulmonary functional capacity. Objective: To analyze the cardiopulmonary function capacity with the 6-minute walk test (6MWT) in patients with chronic renal failure on dialysis treatment. Method: 20 subjects (10 men) participated in this study. Cardiopulmonary functional capacity was assessed by the 6MWT. Descriptive statistics were used to show the mean and standard deviation of the variables. Data were analyzed by paired Student t test comparing the absolute values obtained with the 6MWT and the predicted values by the equation of Iwama et al. (2009). Results: There were significant differences between the values of the walk distance in the 6MWT and values predicted by Iwama et al. 2009. Conclusion: The research verified that there is a significant reduction in the cardiopulmonary functional capacity in patients with chronic renal failure on dialyses treatment.
