Comparação de testes de campo para avaliação capacidade funcional em indivíduos com doença pulmonar intersticial fibrosante

Abstract

Interstitial fibrosing lung disease (IFLD) has been increasing in the world population. This disease affects the pulmonary parenchyma, decreasing pulmonary compliance, altering ventilatory mechanics and reducing the functional capacity of the individual. Field tests have been applied in this population to evaluate functional capacity. The objective of this study was to compare the physiological variables presented in the field tests. Patients with a medical diagnosis of IFLD were recruited from specialized outpatient clinics, such as interstitial diseases and referred to UNINOVE. Anesthesiological evaluation, spirometry, application of dyspnea questionnaires, quality of life and level of physical activity, six-minute walk test (6MWT), Incremental Shuttle Walk Test (ISWT) and Endurance Shuttle Walk Test (ESWT) were performed according to its guidelines. We evaluated 18 individuals of both sexes, age 62.71 ± 4.75 years, with mild pulmonary restriction. According to the predictive equations, 90.28% of predicted in the 6MWT and 70.04% in the ISWT, 7 subjects stopped during the 6MWT. Predicted HRmax was 79.22% in the 6MWT, 78% in the ISWT and 62.62% in the ESWT. 14 patients presented saturation <88% in the 6MWT, 12 in the ISWT and 7 in the ESWT. The 6MWT showed maximum test behavior for this population, but only a functional capacity deficit was verified in the ISWT, according to the predictive equations.
