The Role of Troponin-T Biomarker as an Indicator for Cardiac and Non-Cardiac Complications in Cardiac Patients Undergoing Non-Cardiac Surgery at Dr. Wahidin Sudirohusodo Hospital, Makassar, Indonesia

Abstract

Background: Non-cardiac surgery in patients with cardiovascular risk can lead to postoperative complications. Troponin T, a cardiac biomarker, is proposed as an indicator of cardiac risk in these patients. This study evaluates troponin T levels before and after non-cardiac surgery and their association with postoperative complications. Methods: This prospective cohort study included 46 patients selected through consecutive sampling. Demographic data and troponin T levels were recorded before and 24 hours after surgery. Results: Postoperative complications included cardiac events (15.21%), such as myocardial infarction (4.34%), heart failure (4.34%), and arrhythmia (6.52%), and non-cardiac events (17.39%), such as sepsis (4.34%), bleeding (4.34%), surgical site infection (6.52%), and respiratory insufficiency (2.17%). The average patient age was 50.15 ± 8.81 years, with 60.9% being male. There was a significant relationship between troponin T levels and the incidence of cardiac complications after surgery. Conclusion: Elevated postoperative troponin T levels may serve as a prognostic indicator for cardiac complications in non-cardiac surgery patients. Routine monitoring could aid in early detection and improved postoperative management.
