Title: Diagnostic significance of highly sensitive troponins in cardiac surgery

Abstract

Background: The level of troponins after cardiac surgery always exceeds the reference values, however, the interpretation of these changes is difficult. Aim: To determine the relationship between high-sensitivity cardiac troponin I and troponin T levels and the risk of developing heart failure (HF) within 24 hours after heart surgery.

Methods: A prospective, observational, single-center study included 70 patients undergoing elective heart surgery. Patients were retrospectively divided into two groups based on the development of HF in the first 12 hours after surgery.

Results: The levels of highly sensitive Troponin I (HsT I) in patients who underwent elective heart surgery without complications (n=57) were 61 times higher than the upper reference limit, with HF (n=13). 111 times higher than the upper reference limit. The levels of highly sensitive Troponin T (HsT T) are 25.5 and 51 times higher, respectively. The level of HsT I at the end of the surgery can be a predictor of the development of HF, regardless of the use of cardiopulmonary bypass (threshold value 1483 ng/l), as well as a predictor of the need for inotropic support for 2 days or more, regardless of the type of operation (threshold value 1573 ng/l). There was a direct moderate correlation of HsT I at the end of the operation and 6 hours after the operation with cumulative hemohydrobalance for 24 hours, which was 60% higher in patients with HF than in patients without complications.

Conclusion: In uncomplicated patients, the level of highly sensitive troponins T and I in the postoperative period is 25–61 times higher than the upper reference limit, and with the HF — 51–111 times. Highly sensitive troponins can be considered as predictors of the development of HF and the duration of inotropic support.
