Insights
Elevated preoperative C-reactive protein (CRP) levels predict a higher risk of postoperative infections in cardiac surgery patients. Preoperative CRP measurement can aid in stratifying infection risk.
Area of Science:
- Cardiology
- Infectious Disease
- Clinical Biochemistry
Background:
- Postoperative infections pose a significant risk to patients undergoing cardiac operations.
- Identifying reliable predictors for these infections is crucial for patient management.
Purpose of the Study:
- To investigate the predictive value of preoperative C-reactive protein (CRP) levels for the development of postoperative infections in patients undergoing cardiac surgery.
Main Methods:
- C-reactive protein (CRP) levels were measured preoperatively and on multiple postoperative days in 593 cardiac surgery patients.
- Infectious disease data was collected and analyzed in conjunction with CRP levels.
Main Results:
- Patients who developed postoperative infections had significantly higher preoperative CRP levels compared to uninfected patients.
- A higher incidence of postoperative infections (25.3% vs. 11.2%) and longer hospital stays were observed in patients with elevated preoperative CRP.
- Multivariate analysis identified high preoperative CRP as the strongest predictor of postoperative infection (OR = 2.7).
Conclusions:
- Elevated preoperative CRP levels are associated with an increased risk of postoperative infections in cardiac surgery patients.
- Preoperative CRP measurement serves as a valuable predictive marker for risk stratification of postoperative infections.
Background:
We examined the possible predictive role of preoperative C-reactive protein (CRP) levels for postoperative infections in patients who have cardiac operations.
Methods:
CRP levels were determined on the day before the operation and on postoperative days 1 to 4 and 6 in 593 consecutive patients. Furthermore, we documented infectious disease-related data.
Results:
Patients in whom an infection developed during the postoperative course (n = 87) had significantly higher CRP levels on the day before operation (17.8+/-3.9 mg/L compared with 7.7+/-0.7 mg/L; p<0.001) and on postoperative days 4 and 6. The incidence of postoperative infections was significantly higher in patients with increased preoperative CRP levels than in those with normal preoperative CRP levels (25.3% versus 11.2%, respectively; p<0.001). Furthermore, patients with higher preoperative CRP levels had a significantly longer postoperative hospital stay than those with normal preoperative CRP levels (10.8+/-1.2 days versus 7.8+/-0.3 days; p<0.001). Multivariate analysis, including classic risk factors and increased preoperative CRP levels, demonstrated that higher preoperative CRP was the most important variable predicting postoperative infection (odds ratio = 2.7; 95% confidence interval = 1.7 to 4.3; p<0.001).
Conclusions:
Patients with higher preoperative CRP levels are at increased risk for postoperative infections. Therefore, preoperative measurement of CRP might be a useful, predictive marker in risk stratification for postoperative infections in patients scheduled for cardiac operations.
