Peri-operative Depression and Anxiety of Coronary Artery Bypass Grafting / 中国心理卫生杂志

ABSTRACT

Objective: To investigate the peri-operative incidence of depression and anxiety symptoms of coronary artery bypass grafting (CABG). Methods: 73 patients,who underwent scheduled consecutive CABG between July 2005 and May 2006,were assessed with self-rating depression scale( SDS) and self-rating anxiety scale(SAS)before operation and before leaving hospital.Results: 21 patients (28.8%) had depression and/or anxiety symptoms before CABG, including 11 patients with depression, 7 patients with both depression and anxiety and the other 3 patients had anxiety symptoms. 34 patients (46.6%) had depression and/or anxiety symptoms after CABG, including 18 patients who had depression, 13 patients had both depression and anxiety symptoms and the other 3 patients had anxiety symptoms. The SDS score(47.9?10.0)after surgery was significantly higher than that before surgery(43.7?10) ,t=3.55, P=0.001. The SAS score after surgery (41.6?8.5) was significantly higher than that before surgery (39.3?7.4),t=2.20, P=0.031. Patients with bad mood before operation had lower educational levels (8?3/10?3,t=2.18,P=0.032). Four patients had multiple myocardial infarctions, all of them were in the anxiety-depression group postoperatively (4/34 vs 0/39,P=0.043). There was no difference in post-operative length of hospital stay between the two groups.Conclusions: The peri-operative incidence of depression and anxiety of CABG patients was very high and even higher after surgery. Less education is a risk factor for preoperative depression and anxiety states, multiple infarctions is a risk factor of post operative anxiety and depression.
