Résumé
To investigate the association between preoperative pulmonary function evaluations and surgical outcomes of patients with chronic lung disease following cardiac surgery. This retrospective observational study evaluated 148 patients using preoperative pulmonary function tests before undergoing cardiac surgery. Patients were divided into 4 groups (normal, obstructive, restrictive, and combined disorder), based on the result of the pulmonary function tests. Additionally, we evaluated the percent predicted forced expiratory volume in 1 second. Finally, we investigated the mechanical ventilation duration, length of postoperative hospital stay, and the 30-day mortality rate between the groups in each study. The mechanical ventilation duration and length of postoperative hospital stay in the combined group was significantly longer than that in the other groups (P < .0001, P < .0001, respectively). Patients in the restrictive group had a significantly longer postoperative ventilation or hospitalization than those in the normal group (P = .0479, P = .0164, respectively). However, there were no significant differences in the 30-day mortality rates between the groups. There also was a significant negative correlation between the percent predicted forced expiratory volume in 1 second and mechanical ventilation (R2 = 0.052, P = .0054) and postoperative hospitalization (R2 = 0.042, P = .0122). Risk stratification by preoperative pulmonary function tests may be used to accurately identify the postoperative outcomes in chronic lung disease patients following cardiac surgery.

BACKGROUND
To investigate the association between preoperative pulmonary function evaluations and surgical outcomes of patients with chronic lung disease following cardiac surgery.
METHODS
This retrospective observational study evaluated 148 patients using preoperative pulmonary function tests before undergoing cardiac surgery. Patients were divided into 4 groups (normal, obstructive, restrictive, and combined disorder), based on the result of the pulmonary function tests. Additionally, we evaluated the percent predicted forced expiratory volume in 1 second. Finally, we investigated the mechanical ventilation duration, length of postoperative hospital stay, and the 30-day mortality rate between the groups in each study.
RESULTS
The mechanical ventilation duration and length of postoperative hospital stay in the combined group was significantly longer than that in the other groups (P < .0001, P < .0001, respectively). Patients in the restrictive group had a significantly longer postoperative ventilation or hospitalization than those in the normal group (P = .0479, P = .0164, respectively). However, there were no significant differences in the 30-day mortality rates between the groups. There also was a significant negative correlation between the percent predicted forced expiratory volume in 1 second and mechanical ventilation (R2 = 0.052, P = .0054) and postoperative hospitalization (R2 = 0.042, P = .0122).
CONCLUSION
Risk stratification by preoperative pulmonary function tests may be used to accurately identify the postoperative outcomes in chronic lung disease patients following cardiac surgery.
