TI  - Peak oxygen uptake during the incremental shuttle walk test in a predominantly 
      female population with Chagas heart disease.
PG  - 20-7
AB  - BACKGROUND: Chagas heart disease (CHD) patients may have a reduced functional 
      capacity (FC). Field tests, as the Incremental Shuttle Walk Test (ISWT), can 
      estimate peak oxygen uptake (VO2 peak). However, the relationship between the 
      ISWT and the Cardiopulmonary Exercise Testing (CPET), the gold standard in the 
      assessment of FC, is not well established in CHD patients. AIM: This study aimed 
      to evaluate the FC of CHD patients by ISWT with direct measurement of VO2 peak 
      and to compare these findings with data obtained from CPET. A secondary goal was 
      to derive a regression equation to calculate the VO2 peak by ISWT. DESIGN: 
      Cross-sectional and correlative study. SETTING: Research laboratory setting. 
      POPULATION: Thirty-two CHD patients (58.8+/-9.0 years, 81.3% women) participated in 
      this study. METHODS: Eligible patients underwent clinical evaluation, 
      echocardiography, CPET by ramp protocol and ISWT according to current guidelines. 
      RESULTS: The distance walked in ISWT showed a positive correlation with VO2 peak 
      from CPET and ISWT (r=0.456, P=0.009 and r=0.869, P<0.001, respectively). In the 
      agreement analysis, the values of the differences between VO2 peak from CPET and 
      ISWT showed absence of bias (mean bias +/-95% CI and mean -1.29+/-5.09 mL.kg.min). 
      Based in real values of VO2 obtained from ISWT, one equation including sex, 
      functional class and distance walked was provided to predict the VO2 values in 
      this test. CONCLUSION: This study showed the good correlation between distance 
      walked in ISWT and VO2 peak directly measured in both tests, and additionally, 
      provided an equation to calculate a predictive VO2 peak by ISWT, suggesting a 
      good alternative to evaluate the FC of CHD patients, especially in locations 
      where sophisticated testing is not available. CLINICAL REHABILITATION IMPACT: The 
      results confirm the possibility of using the ISWT for the evaluation of the FC in 
      patients with CHD, especially in locations where sophisticated testing is not 
      available.
