Insights
Depression is common in patients before and after coronary artery bypass graft (CABG) surgery, affecting 19-37% pre-operatively and 15-33% post-operatively. Early detection of depression can identify at-risk patients.
Area of Science:
- Cardiology
- Psychiatry
- Medical Statistics
Background:
- Coronary artery bypass graft (CABG) surgery can negatively impact patient health.
- Cognitive deterioration and depression are common adverse effects post-CABG.
Purpose of the Study:
- To analyze the prevalence of depression in patients before and after CABG surgery.
- To systematically review and meta-analyze existing research on depression in CABG patients.
Main Methods:
- Systematic review and meta-analysis of studies from the past 10 years.
- Searched databases: CINAHL, LILACS, MEDLINE, PsycINFO, SciELO, Scopus, Web of Science.
- Included 29 studies with a total of 16,501 patients.
Main Results:
- Pre-CABG depression prevalence ranged from 19% to 37%.
- Post-CABG depression prevalence ranged from 15% to 33%.
- Prevalence varied based on measurement tools and study quality.
Conclusions:
- Significant prevalence of depression exists in patients undergoing CABG.
- Systematic depression screening before cardiac surgery is recommended to identify at-risk individuals.
Abstract:
Coronary artery bypass graft surgery (CABG) might adversely affect the health status of the patients, producing cognitive deterioration, with depression being the most common symptom. The aim of this study is to analyse the prevalence of depression in patients before and after coronary artery bypass surgery. A systematic review and meta-analysis was carried out, involving a study of the past 10 years of the following databases: CINAHL, LILACS, MEDLINE, PsycINFO, SciELO, Scopus, and Web of Science. The total sample comprised n = 16,501 patients. The total number of items was n = 65, with n = 29 included in the meta-analysis. Based on the different measurement tools used, the prevalence of depression pre-CABG ranges from 19-37%, and post-CABG from 15-33%. There is a considerable presence of depression in this type of patient, but this varies according to the measurement tool used and the quality of the study. Systematically detecting depression prior to cardiac surgery could identify patients at potential risk.
