[The role of cardiac biomarkers in perioperative risk evaluation of noncardiac surgery patients-A summary of the ESAIC guidelines 2023].

BACKGROUND: The recently published ESAIC guidelines highlight the clinical value of cardiac troponins (cTn) and B‑type natriuretic peptides (BNP) for risk assessment in patients undergoing noncardiac surgery.

OBJECTIVE: Summary of the ESAIC guideline recommendations.

MATERIAL AND METHODS: The evidence for the recommendations was extracted from studies that investigated the perioperative role of cTn and BNP as prognostic factors, for risk prediction and for therapeutic guidance. To collate this evidence 12 relevant endpoints as well as risk benefit analyses of systematic screening were considered to issue the strength of the recommendations.

RESULTS: The body of evidence for these guidelines was based on 115 studies. The evidence varied significantly across the 12 predefined endpoints. Additionally, there was a gradient in evidence for the use of cTn and BNP as prognostic factors, for risk prediction and for therapeutic guidance. The guidelines issue a weak recommendation for the use of preoperative, postoperative and combined measurement of cTn as well as for preoperative BNP measurement to assess the prognosis. For risk prediction a weak recommendation was formulated for combined and postoperative cTn and preoperative BNP measurements. No recommendation could be given for the evidence on biomarkers as data were very limited.

CONCLUSION: Both cTn and BNP can be used as prognostic factors or to predict the risk for selected endpoints. Therapeutic interventions should not be guided by cardiac biomarker levels.
