Preoperative mild cognitive dysfunction predicts pulmonary complications after coronary artery bypass graft surgery.
OBJECTIVES In elderly patients with mild cognitive impairment , noncompliance with respiratory exercises , ineffective expectoration , reluctance in mobilization , and difficulty in learning the use of drugs such as inhalers were observed in the early postoperative period after coronary artery bypass graft surgery . It was hypothesized that respiratory complications may be more frequent in these patients , and so the postoperative respiratory complications in patients with preoperative mild cognitive impairment were compared with the postoperative respiratory complications of a control group . DESIGN A prospect i ve cohort control . SETTING A university hospital . PARTICIPANTS Patients undergoing elective coronary artery bypass graft surgery . INTERVENTIONS Investigators separated 48 patients > 70 years old who were scheduled for elective coronary artery bypass graft surgery into two groups : patients with preoperative mild cognitive impairment  ( group A , n = 25 ) and patients with no cognitive impairment  ( control group ; group B , n = 23 ) . The patients ' cognitive status was evaluated preoperatively by the Montreal Cognitive Assessment test . MEASUREMENTS AND MAIN RESULTS Pulmonary functions and respiratory complications were evaluated via chest x-rays and spirometry tests preoperatively and postoperatively . A significant difference was observed between the groups , particularly with regard to atelectasis and prolonged ventilation ( p<0.001 and p<0.05 ) . No significant impairment was observed in the spirometry tests of the control group . However , a significant deterioration was observed in the postoperative spirometry tests of patients with preoperative mild cognitive impairment . CONCLUSIONS This study suggested that mild cognitive impairment was associated with pulmonary complications after coronary artery bypass graft surgery
