Sleep disturbance is associated with poorer outcomes in cardiac patients, but little is known about the independent role of sleep quality in coronary artery bypass graft (CABG) patients.
This study aims to examine the relationship between preoperative sleep complaints and post-operative emotional and physical recovery in CABG surgery patients, independently of demographic, clinical and mood factors.
Two hundred thirty CABG patients (aged 67.81 ± 9.07 years) completed measures of self-reported sleep complaints before surgery and health-related quality of life (HRQoL), physical symptoms and pain 2 months after surgery.
Greater sleep complaints prior to surgery were associated with greater physical symptoms, poorer physical HRQoL and greater sensory pain after surgery (p < 0.05), but not with affective pain or mental HRQoL. Preoperative mood was not able to explain these associations.
Sleep complaints may be implicated in physical recovery from CABG surgery but further work is needed to understand the role of causal pathways.
