EXPRESS: Impact of anesthesia precision intervention on perioperative serum myocardial injury markers and major adverse cardiac events in high-risk cardiovascular patients undergoing non-cardiac surgery.

This study aims to unravel the impact of anesthesia precision intervention on perioperative serum myocardial injury markers and major adverse cardiac events in high-risk cardiovascular patients undergoing non-cardiac surgery. One hundred and sixty high-risk cardiovascular disease patients were randomly allocated into two groups. The control group received conventional empirical management, while the observation group underwent precise anesthesia interventions. We compared the general data, the levels of myocardial injury markers, including cardiac troponin (cTn), creatine kinase isoenzyme (CK-MB), and myoglobin (Mb). Furthermore, the levels of cardiac function markers, such as brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), as well as the levels of inflammatory factors and the incidence of adverse cardiac events were compared between the two groups. Postoperatively, the observation group exhibited significantly lower levels of cTn, CK-MB, Mb, BNP, NT-proBNP, c-reactive protein (CRP). Additionally, the total incidence of adverse cardiac events in the observation group was noticeably lower than that in the control group. The application of precise anesthetic intervention in the perioperative period of non-cardiac surgery for high-risk cardiovascular patients can further mitigate cardiac injury and reduce the incidence of adverse cardiac events, making it worthy of clinical application.
