AB  - The 6-minute walk test (6MWT) has been applied to assess postsurgical recovery in 
      cardiac populations. This study mainly investigated whether the 6MWT could serve 
      as an indicator for physical functioning in patients undergoing cardiac 
      surgery.Participants completed the 6MWT and the Medical Outcomes Study 36-Item 
      Short-Form Health Survey (SF-36) at baseline, discharge, and 3 months 
      postoperatively, in order to analyze the construct validity and responsiveness of 
      the 6MWT. The participants in this study were 125 patients (92 males and 33 
      females) with an average age of 65.1 +/- 11.1 years. The mean 6MWT was 308.9 +/- 77.3 
      m in the preoperative phase, decreased to 277.3 +/- 85.7 m at discharge, and 
      returned to 378.1 +/- 95.2 m at 3-month follow-up. The results showed that the 
      6-minute walk distances at baseline and at 3-month follow-up were moderately to 
      highly correlated with the physical functioning subscale of the SF-36 (rs = .44 
      and .54, respectively) and had weak correlation with the nonphysical functioning 
      subscales. The recovery level of physical functioning is meaningfully associated 
      with the 6MWT change from baseline to discharge and from baseline to 3-month 
      follow-up. Patients with higher New York Heart Association (NYHA) Functional 
      Classification levels had lower 6MWT. Additionally, the 6MWT was sensitive to 
      change during the perioperative period (effect sizes from -0.51 to 1.72).The 
      supporting evidence includes the construct validity and responsiveness of the 
      6MWT. This study supports the feasibility of the 6MWT as an evaluation tool of 
      physical functioning for assessment of postcardiac surgical recovery.
