Zusammenfassung: | Patients undergoing noncardiac surgery have varying risk of cardiovascular complications. This study evaluated preoperative N-terminal pro-B-type natriuretic peptide and high-sensitivity cardiac troponin T to enhance cardiovascular events prediction for major noncardiac surgery.
This prospective cohort study included adult patients with cardiovascular disease or risk factors undergoing elective major noncardiac surgery at four hospitals in China. Blood samples were collected within 30 days before surgery for N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin T measurements. The primary outcome was a composite of any cardiovascular events within 30 days after surgery. Logistic regression models were used to assess associations, and the predictive performance was evaluated primarily using area under the receiver-operating-characteristic curve (AUC) and fraction of new predictive information.
Between June 2019 and September 2021, 2833 patients were included, with 435 (15.4%) experiencing the primary outcome. In the logistic regression model that included clinical variables and both biomarkers, the odds ratio for the primary outcome was 1.68 (95% CI 1.37-2.07) when comparing the 75th percentile to the 25th percentile of N-terminal pro-B-type natriuretic peptide distribution, and 1.91 (95% CI 1.50-2.43) for high-sensitivity troponin T. Each biomarker enhanced model discrimination beyond clinical predictors, with a change in AUC of 0.028 for N-terminal pro-B-type natriuretic peptide and 0.029 for high-sensitivity cardiac troponin T, and a fraction of new information of 0.164 and 0.149, respectively. The model combining both biomarkers demonstrated the best discrimination, with a change in AUC of 0.042 and a fraction of new information of 0.219.
Preoperative N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin T both improved the prediction for cardiovascular events after noncardiac surgery in addition to clinical evaluation, with their combination providing maximal predictive information. |
