ReviewDepression and anxiety and outcomes of coronary artery bypass surgery
Section snippets
Material and methods
The identification of articles in English language peer-reviewed journals was obtained by using PubMed from 1980 to 2001 (www.ncbi.nlm.nih.gov/PubMed), with key words as follow: depression, anxiety, mood disorder, and coronary artery bypass graft surgery. The articles were also identified by searching on any author who had contributed one relevant article and by using the function “related articles” in PubMed.
Overview of epidemiology of depression and anxiety in coronary artery disease
Many studies conducted over the last 10 years have documented that the prevalence of depression is increased among patients with various manifestations of CAD, including those recently hospitalized for an acute myocardial infarction (AMI) 7, 8, unstable angina [9], congestive heart failure [10], and coronary catheterization or angioplasty 11, 12. There is also evidence of an increased prevalence in patients with stable coronary artery disease [13], and at 6 months and 1 year after an AMI [14].
Depression and anxiety before and after bypass surgery
In contrast to the large number of studies documenting relationships between depression and anxiety and cardiovascular disease outcomes, relatively few studies have examined links between psychological symptoms and morbidity and mortality after CABG. Although there is some evidence that surgery may be associated with better psychological and social outcomes after AMI than nonsurgical treatment [25], symptoms of anxiety, depression, or reactive stress are commonly reported among patients with a
Pathophysiology
The factors that link major depression or depressive symptoms, and possibly anxiety, to an increased risk of postsurgical morbidity and mortality remain unclear. In addition to the pathophysiological disturbances postulated to underlie relationships between depression and anxiety and prognosis in CAD patients, several factors specific to cardiac surgery may be involved in CABG patients.
According to several reviews of the current data, symptoms of depression, and to some extent anxiety, may
Interventions before surgery
Evaluation and psychological support specifically designed to reduce the apprehension and emotional tension experienced by CAD patients before cardiac surgery may prevent adverse effects, thus facilitating postoperative recovery and reducing the cost of care [64]. Given that symptoms of anxiety and depression are common in patients scheduled for CABG [26] and can influence the outcome of the procedure, detection of these symptoms during the preoperative evaluation is essential. Structured
Comment
Depression and anxiety are well-recognized cardiovascular risk factors, similar in importance to smoking and hypertension, and must be detected and treated. These psychological disorders can affect the outcomes of cardiovascular disease by numerous pathophysiological mechanisms.
Furthermore, recent studies have confirmed that symptoms of depression or anxiety are associated with worse outcomes after CABG, often with a marked alteration in quality of life. Careful routine evaluation of these

2019, Journal of Geriatric OncologyCitation Excerpt :A gradual rather than a rapid recovery process was observed for the older patients, and fatigue was common, lasting for 3 to 6 months after surgery [42]. Other studies have shown a higher prevalence of postoperative depression in the older population [45,46], which was confirmed in this study by a longer emotional recovery in older patients [42]. The present study showed a higher survival rate for patients treated at Moffitt; these differences seem to be largely explained by differences in treatment strategy between the Netherlands and Moffitt.
Effectiveness of Preoperative Visitation on Postanesthesia Complications
2018, Journal of Perianesthesia NursingCitation Excerpt :Some physiological indices like systolic blood pressure, diastolic blood pressure, and heart rate change during a stressful condition.25 Preoperative anxiety may produce negative impacts on these physiological parameters pre- and perianesthesia, and prolong the recovery.26 In the present study, the short interval between the intervention and surgery (<24 hours) may be one cause of ineffectiveness of the intervention in the improvement of vital signs (systolic and diastolic blood pressure, and respiratory and heart rates) in the intervention group.
