Abstract
Background: Myocardial infarction is the most common cause of the morbidity and mortality in noncardiac surgery. High-sensitivity Troponin T (hs-Troponin T) assay has been reported to increase the myocardial injury after non-cardiac surgery (MINS). The objective of this study was to study the change of hs-Troponin T in elderly patients after laparoscopic surgery and to determine the related factors. Materials and Method: Cross - sectional study of 117 patients ≥ 60 years old undergo laparoscopy surgery. hs-Troponin T was measured before surgery and at day 1, 2, and 3 after surgery. MINS was defined as an absolute hs-Troponin T increase of ≥ 14 ng/L from preoperative to postoperative measurements. Results: hs-Troponin T increase of ≥ 14 ng/L was detected in 29.9%. Myocardial injury occurred in 7.7% cases. RCRI ≥ 2, intraoperative heart rate > 100/min or < 50/min, intraoperative hypotension were independent risk factors for myocardial injury. Conclusion: There's elevated hs-Troponin T inelderly patients after laparoscopy
