Insights
Elevated high-sensitivity C-reactive protein (hsCRP) predicts depression risk in coronary artery bypass grafting (CABG) patients. This inflammation marker is linked to depression both before and up to six months after CABG surgery.
Area of Science:
- Cardiology
- Psychiatry
- Biomarkers
Background:
- Depression is a common comorbidity in patients undergoing coronary artery bypass grafting (CABG).
- Preoperative inflammation, indicated by high-sensitivity C-reactive protein (hsCRP), may influence the risk of depression in these patients.
Purpose of the Study:
- To investigate the association between preoperative high-sensitivity C-reactive protein (hsCRP) levels and the risk of depression in patients undergoing coronary artery bypass grafting (CABG).
Main Methods:
- A cohort of 232 patients undergoing elective CABG were assessed for depression using the 9-item Patient Health Questionnaire scale preoperatively and at 6 months post-surgery.
- Serum hsCRP levels were measured at baseline, and logistic regression analysis was used to identify predictors of depression.
Main Results:
- The prevalence of depression was 18.1% preoperatively and postoperatively.
- Preoperative depression was associated with female sex and elevated log-transformed hsCRP.
- Postoperative depression was independently associated with log-transformed hsCRP, even after adjusting for medications and cardiovascular events.
Conclusions:
- Elevated serum hsCRP is an independent predictor of depression in CABG patients, both before and up to six months after surgery.
- hsCRP may represent a potential therapeutic target for improving the prognosis of CABG patients experiencing depression.
Objective:
Our objective was to reveal the contribution of preoperative high-sensitivity C-reactive protein (hsCRP) levels to the risk of depression in patients undergoing coronary artery bypass grafting (CABG).
Methods:
In this study, 232 consecutive patients undergoing elective CABG were evaluated for depression utilizing the 9-item Patient Health Questionnaire scale at least 3 days before surgery and 6 months after CABG. In addition, peripheral blood samples were collected at baseline and the circulation levels of hsCRP were measured.
Results:
The preoperative and postoperative rate of depression was 18.1%. Interestingly, preoperative depression was independently associated with women (odds ratio [OR], 2.49; 95% confidence interval [CI], 1.13-5.50) and log-transformed hsCRP (OR, 1.16; 95% CI, 1.06-1.27) after adjusting for various factors using logistic regression, including age, sex, and university-level education. Postoperative depression was only associated with log-transformed hsCRP (OR, 1.15; 95% CI, 1.05-1.25) in these patients. Log-transformed hsCRP remained associated with future depression after adjusting for postoperative medications or major adverse cardiovascular events during the follow-up period.
Conclusions:
The present study is the first to report elevated serum hsCRP is an independent predictor for depression in CABG patients not only preoperatively but also up to 6 months after surgery. These clinical findings may reveal a potential target for improving prognosis in CABG patients with depression.
