OBJECTIVE To understand the association between pre-operative depression symptoms, including cognitive and somatic symptom subtypes, and length of post-operative stay in patients undergoing coronary artery bypass graft (CABG) surgery, and the role of socioeconomic status (SES). METHODS We measured depression symptoms using the Beck Depression Inventory(More)
BACKGROUND 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. PURPOSE This study aims to examine the relationship between preoperative sleep complaints and post-operative emotional and physical recovery in CABG surgery(More)
This study aimed to explore the role of C-reactive protein (CRP) in mediating the association between greater pre-operative depression symptoms and longer post-operative length of stay in patients undergoing coronary artery bypass graft (CABG) surgery. We used a sample of 145 elective CABG patients and measured depression symptoms using the Beck Depression(More)
This randomised controlled experiment tested whether a brief subjective well-being intervention would have favourable effects on cardiovascular and neuroendocrine function and on sleep. We compared 2 weeks of a gratitude intervention with an active control (everyday events reporting) and no treatment conditions in 119 young women. The treatment elicited(More)
PURPOSE There is growing evidence that the hypothalamic-pituitary-adrenal axis plays a role in the progression of cardiovascular disease. We examined the relationship between diurnal cortisol rhythm and adverse events in patients undergoing coronary artery bypass graft (CABG) surgery. We hypothesized that a flatter presurgical diurnal cortisol slope would(More)
OBJECTIVE Optimism is thought to be associated with long-term favourable outcomes for patients undergoing coronary artery bypass graft (CABG) surgery. Our objective was to examine the association between optimism and post-operative pain and physical symptoms in CABG patients. METHODS We assessed optimism pre-operatively in 197 adults undergoing CABG(More)
OBJECTIVE To examine the association between psychological factors and length of intensive care unit (ICU) stay in patients undergoing elective coronary artery bypass graft (CABG) surgery. METHOD We studied 212 adults undergoing CABG surgery preoperatively to assess depression symptoms, anxiety symptoms, and illness perceptions and then followed them up(More)
OBJECTIVE The mechanisms underlying the association between adult attachment and health are not well understood. In the current study, we investigated the relationship between attachment anxiety, attachment avoidance, inflammation, and length of hospital stay in coronary artery bypass graft (CABG) surgery patients. METHOD 167 CABG patients completed an(More)
The percentage of regulatory T cells (TRegs)—a subtype of T lymphocyte that suppresses the immune response—appears to be reduced in a number of stress-related diseases. The role of the TReg in stress-disease pathways has not yet been investigated. The aim of the study was to investigate the association between biological responsivity to acute psychosocial(More)
