Resumo

The 6-minute walking test (6MWT) is a submaximal test
used as a clinical indicator of functional capacity in patients
with pulmonary disease. However, is has not been defined
whether the parameters obtained in the 6MWT are similar
in two groups of interstitial lung diseases (ILD), systemic sclerosis
(SSc) and idiopathic pulmonary fibrosis (IPF), and what
are the differences when compared to patients with chronic
obstructive pulmonary disease (COPD). This is a comparative
cross-sectional study of 6MWT data, with the inclusion of 32
patients with SSc, 32 with IPF and 50 with COPD. All patients
underwent the 6MWT and a respiratory function test. Patients
with ILD did not present significant differences when compared
with each other. However, when compared to patients
with COPD, the ILD group showed greater distance walked
(ILD = 404.6 ± 1.09m, COPD = 352.4 ± 10.80m; p = 0.0033) and
predicted percentage above 100% (ILD = 113.5 ± 3.72%, COPD
= 84.36 ± 4.81%; p <0.0001). Both groups showed a drop in
blood oxygen saturation (SaO2) at the end of the test, but the
difference between the measured values before and after the
6MWT was more significant in the ILD group (ILD = 10.33 ±
01.09%, COPD = 4.60 ± 12.37%; p <0.0001). The data suggest
that, differently from COPD patients, the main parameter to
be evaluated during the 6MWT in the ILD group could be the
drop in saturation and not the distance walked.
