Incident delirium was diagnosed postoperatively with a structured clinical interview and patients were monitored every day post-operatively for confusion and disturbance in consciousness.Results Delirium developed in 63 persons （35% of sample）. After adjustment for covariates, delirium was significantly associated with depression [odds ratio （OR）： 1.08; 95% confidence interval （CI）： 1.03-1.13,P = 0.003], anxiety （OR： 1.07; 95% CI： 1.02-1.13,P= 0.01） and stress （OR： 1.05; 95% CI： 1.00-1.09,P= 0.03）. Preoperative depression scores were associated with poorer QOL including bodily pain （β =-0.39,P = 0.013）, vitality （β=-0.32,P = 0.020）, social functioning （β=-0.51,P≤0.001）, emotional role function （β=-0.44,P = 0.003） and general health （β=-0.33,P = 0.038）. Among the covariates, harmful levels of alcohol use was consistently associated with poorer QOL.Conclusions Depression and harmful levels of alcohol use were consistently associated with poorer QOL whereas depression, anxiety and stress were associated with delirium risk. These findings point to further research examining depression and harmful levels of alcohol use in coronary heart disease populations undergoing coronary revascularization.展开更多
