Objective: The aim of this preliminary study was to evaluate the feasibility of exercise testing (ET) for predicting postoperative complications in patients with impaired pulmonary function. Methods: Thirteen patients were prospectively enrolled. The enrollment criteria were FEV1.0% < 70% and emphysema score > 8 by the Goddard classification or interstitial pneumonia on chest computed tomography. Patients underwent testing for pulmonary function, six-minute walking test (6MWT), and stair-climbing test (SCT). Postoperative cardiopulmonary complications (PCPCs) were recorded. Results: Four patients developed PCPCs. There were no significant differences between the patients with PCPCs (n = 4) and those without PCPCs (n = 9) for background data and PFT. The distances achieved in the 6MWT were 503 ± 72.7 m for patients without PCPCs and 369 ± 50.7 m for patients with PCPCs (p = 0.011). The SCT climbing heights were 20.4 ± 5.3 m for patients without PCPCs and 14.9 ± 4.0 m for patients with PCPCs (P = 0.187). Cut-off points, including a 6MFT distance of less than 400 m, SCT height lower than 15 m, and SCT climbing speed less than 8.5 m/min, were predictive of CPCP. Conclusions: Exercise testing is more feasible for predicting postoperative cardiopulmonary complications than stationary pulmonary function testing.
