To investigate the presence and severity of depression before and after operation in patients undergoing coronary artery bypass grafting (CABG) and the effect thereof on the quality of life. A validated Chinese version of Beck Depression Inventory (BDI) was used in 138 CABG patients that were divided into 2 groups according the fact if depression was present. 1 week before and 1, 3, and 6 months after operation, and SF-36 scale was used to evaluate the quality of life (QOL) one week before operation and 1 and 6 months after operation. Depressive disorders occurred in 42.7% of the patients preoperatively and in 23.1% of the patients 6 months after the operation. There were no significant differences in all the dimensions of the SF-36 scale before operation between the depression and non-depression groups. All the scores of the 36-F dimensions were improved 1 and 6 months after the operation. However, the SF-36 social functioning (SF), mental health (MH), role emotional (RE), and bodily pain (BP) subscale scores 6 months after operation of the depression group were all lower than those in the non-depressive groups (all P < 0.05). Depression symptoms at different degrees exist before CABG and can be improved post-operatively. The improvement of QOL of the depressive patients after operation is not so marked compared to the non-depressive patients, especially in SF, MH, RE, and BP dimensions.
