Eversion Carotid Endarterectomy: Cardiac Troponin Assessment

Area of Science:

• Cardiology
• Vascular Surgery
• Biomarkers

Background:

• Myocardial infarction (MI) is a known complication of eversion carotid endarterectomy (eCEA), but its true incidence and correlation with troponin levels remain debated.
• Routine cardiac troponin measurement is crucial for identifying MI, guiding treatment, and stratifying risk in surgical patients.

Purpose of the Study:

• To assess the impact of troponin elevation following eCEA.
• To investigate the correlation between cardiovascular events and postoperative MI incidence after emergent vascular surgery.

Main Methods:

• Evaluated 54 patients undergoing eCEA.
• Routinely monitored high-sensitive troponin I (hsTnI) pre- and postoperatively.
• Correlated hsTnI increases with clinical factors and cardiovascular events.

Main Results:

• 13% of patients showed elevated hsTnI postoperatively.
• Eight patients were diagnosed with silent non-ST segment elevation MI.
• No correlation found between hsTnI elevation and comorbidities or surgical risk factors.

Conclusions:

• hsTnI elevation after eCEA often indicates silent MI in the early postoperative period.
• hsTnI monitoring may serve as a valuable tool for diagnosing cardiovascular events during hospitalization.
