Abstract

The aim of this study was to investigate the impact of the different degrees of severity of `CAT' in the functional capacity evaluated by the 6-minute walk test (6MWT). This is a cross-sectional study, which included spirometrically defined COPD patients, out of exacerbation period and with motor and cognitive skills necessary to perform the spirometry and the 6MWT and reply to the `CAT' questionnaire. We sorted groups according to the clinical impact proposed by `CAT': mild, moderate, severe and very severe. We included 66 COPD patients, with FEV1 (% pred) averages of 53.1 +/- 21.9, 51.4 +/- 14.1, 50.6 +/- 12.8 and 46.4 +/- 13.0, which corresponded to the clinical impact of `CAT', respectively (p > 0.05). The highest `CAT' score, observed on mild, moderate and severe clinical impact did not determine the shortest walking distance in the 6MWT (p < 0.05). However, `CAT' score > 30 (very severe clinical impact) was associated with shorter walking distance in the 6MWT (p < 0.05). We found no negative correlation between `CAT' and 6MWT (p = 0.0707 and r = -0.2479). `CAT' was not associated to 6MWT. (AU)
