Insights
Elevated levels of brain natriuretic peptide (BNP), cardiac troponin (cTn), and high-sensitivity C-reactive protein (hs-CRP) significantly predict major adverse cardiovascular events (MACE) after noncardiac surgery. These biomarkers indicate a substantially increased risk for patients.
Area of Science:
- Cardiology
- Biomarker Research
- Surgical Risk Assessment
Background:
- Noncardiac surgery poses cardiovascular risks.
- Predictive biomarkers for postoperative major adverse cardiovascular events (MACE) are crucial.
- Brain natriuretic peptide (BNP), cardiac troponin (cTn), and C-reactive protein (CRP) are potential indicators.
Purpose of the Study:
- To systematically evaluate the predictive effectiveness and accuracy of BNP, cTn, and hs-CRP for MACE in noncardiac surgery patients.
- To synthesize evidence from existing studies on these biomarkers' association with adverse cardiovascular outcomes.
Main Methods:
- A meta-analysis of 26 studies involving 7,877 participants.
- Data systematically collected from PubMed, Embase, CNKI, CQVIP, and Wanfang databases.
- Statistical analysis performed using Review Manager 5.3 and Stata/SE 12 software.
Main Results:
- Elevated BNP/NT-proBNP, cTnI/cTnT, and hs-CRP were strongly associated with increased MACE risk.
- BNP/NT-proBNP elevation increased MACE risk by approximately 4-fold (RR: 3.92).
- cTnI/cTnT elevation was linked to nearly a 5-fold higher MACE risk (RR: 5.52).
- hs-CRP elevation was associated with a nearly 4-fold higher MACE risk (RR: 3.73).
Conclusions:
- BNP/NT-proBNP, cTnI/cTnT, and hs-CRP elevations predict a significantly higher risk of postoperative MACE.
- These biomarkers are valuable tools for risk stratification in patients undergoing noncardiac surgery.
- Pre- or immediate post-operative assessment of these biomarkers can aid in identifying high-risk individuals.
Abstract:
Objective: The present meta-analysis was aimed to systematically evaluate the effectiveness and accuracy of brain natriuretic peptide (BNP), cardiac troponin (cTn), high sensitive C reactive protein (hs-CRP) and CRP for predicting postoperative major adverse cardiovascular events (MACE) in patients undergoing noncardiac surgery. Methods: A total of 26 relevant studies with 7,877 participants were collected from five databases, namely PubMed, Embase, China National Knowledge Infrastructure (CNKI), CQVIP and the Wanfang Database until August 10, 2018. And the Review Manager Version 5.3 and Stata/SE 12 software were used for data syntheses in the meta-analysis. Results: Strong relationships of BNP/NT-proBNP, cTnI/cTnT and hs-CRP with MACE were detected in patients undergoing noncardiac surgery, and the five biomarkers all increased the risk of MACE. Compared to normal levels, elevated BNP/NT-proBNP could increase the MACE risk by almost 4-fold [RR:3.92, 95%CI: 3.23-4.75, P < 0.001]; elevated BNP corresponded to a 4.5-fold risk [RR:4.57, 95%CI: 3.37-6.20, P < 0.001]; elevated NT-proBNP led to a 3-fold higher risk [RR:3.48, 95%CI: 2.71-4.46, P < 0.001]. Comparing with normal levels of cTnI/cTnT, increased cTnI/cTnT was associated with nearly 5-fold more higher risk of MACE [RR:5.52, 95%CI: 4.62-6.58, P < 0.001]; elevated cTnI faced a 5-fold risk [RR:5.21, 95%CI: 3.96-6.86, P < 0.001]; elevated cTnT resulted in nearly 6-fold higher risk [RR:5.73, 95%CI: 4.55-7.22, P < 0.001]. The elevation of hs-CRP was associated with nearly 4-fold higher risk of MACE in comparison with normal concentration [RR:3.73, 95%CI: 2.63-5.30, P < 0.001]. Conclusion: According to the results of our meta-analysis, the elevations of BNP/NT-proBNP, cTnI/cTnT, and hs-CRP, pre-operation or post-operation immediately, can predict much higher risk of postoperative MACE in patients undergoing noncardiac surgery.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
