“…[13] Although the diagnostic criteria for BCI are currently not uniform, TnI greatly contributes to BCI diagnosis, and previous clinical studies depicted that if ECG findings and TnI levels were normal, the predicted value was 100% for clinical exclusion of severe BCI. [14] The current guidelines recommended TnI monitoring for trauma patients with suspected cardiac injury, [3] but the specific monitoring time and clinical significance were still unclear, and there are few reports on the trend of TnI changes in trauma patients. Our study showed that the peak of TnI appeared about 48 hours after admission, and then gradually decreased.…”
