Resumen

SANTOS, Jefferson J. A.  y  BROFMAN, Paulo R. S.. Six-minute walk test and quality-of-life in heart failure: a correlative study with a Brazilian sample. Insuf. card. [online]. 2008, vol.3, n.2, pp. 72-75. ISSN 1852-3862.

Background. Quality-of-life and functional capacity in heart failure are, actually, between the most investigated topics in the scientific community. Patient's self perceptions and exercise capacity can help health professionals with prognosis and decisions in heart failure treatment. Specifically in Brazil, the research on quality-of-life still needs to focus on the differences in the multifactor aspects of heart failure. The aim of this study is to investigate the correlation between quality-of-life and functional capacity in a sample of Brazilian heart failure patients. Methods. 30 male heart failure patients were included in the study. Quality-of-life was assessed by the Brazilian version of the Minnesota Living with Heart Failure Questionnaire and the functional capacity through the six-minute walk test. Differences in quality-of-life among the functional classes were evaluated through the analysis of variance and the association between the variables was assessed through Pearson's coefficient. Results. Quality-of-life decreased significantly according to functional class (functional class I= 20±11, class II= 35.9±18 and class III= 58.3±24) and correlated significantly to the distance (r=-0.62, p=0.004). Conclusions. Longer distances obtained in the six-minute walk test can be interpreted as a better quality-of-life in Brazilian heart failure patients.
