Abstract | BACKGROUND: Cardiac troponin I (cTnI) levels are usually measured in primary evaluations of blunt cardiac injury ( BCI) patients. We evaluated the associations of cTnI levels with the outcomes of BCI patients at different times. METHODS: From 2015 to 2019, blunt chest trauma patients with elevated cTnI levels were compared with patients without elevated cTnI levels using propensity score matching (PSM) to minimize selection bias. The cTnI levels at different times in the survivors and nonsurvivors were compared. RESULTS: A total of 2,287 blunt chest trauma patients were included, and 57 (2.5%) of the patients had BCIs. PSM showed that patients with and without elevated cTnI levels had similar mortality rates (13.0% vs. 11.1%, p-value = 0.317], hospital lengths of stay (LOSs) [17.3 (14.4) vs. 15.5 (22.2) days, p-value = 0.699] and intensive care unit (ICU) LOSs [7.7 (12.1) vs. 6.4 (15.4) days, p-value = 0.072]. Among the BCI patients, nonsurvivors had a significantly higher highest cTnI level during the observation period than survivors. Additionally, patients who needed surgical intervention had significantly higher highest cTnI levels than patients who did not. CONCLUSIONS: An elevated cTnI level is insufficient for the evaluation of BCI and the determination of the need for further treatment. The highest cTnI level during the observation period may be related to mortality and the need for surgery in BCI patients.
