    Mean ± SD FVC, FEV1, PImax, and PEmax, expressed as percentage of predicted (pred) in the preoperative period, 7 and 30 days postoperation in patients randomized to cardiopulmonary rehabilitation (Rehab) or usual care (Control). Two-way analysis of variance for repeated measures revealed time and interaction effects in the 4 variables (P<.05). *P<.05 for the Tukey test comparing groups.

  • Image Result
    Scatterplot of the association between PImax and VO2peak at 30 days after CABG. There was a highly significant correlation between the variables (r=.90; P<.001). Abbreviation: Rehab, rehabilitation.
