The current study was performed in order to assess the impacts of an initially elevated troponin (TnI) value upon admission on cardiopulmonary (CP) parameters within the first 24 h of ICU treatment:.We identify subsequent findings:.•Patients with an elevated troponin (TnI) value upon admission had a significantly higher need for NAR and FiO2 within the first 24 h of the ICU treatment.•TBI patients with initially raised TnI values had a lower GCS score, higher head AIS score, APACHE II score upon admission.•Initial elevated TNI value was associated with a higher mRS score, lower GOS score at discharge, and increased intra-hospital mortality.•TnI value could be a helpful early biomarker to improve ICU treatment in order to detect patients who could potentially develop CP complications.
Cardiopulmonary (CP) complications are well-known phenomena after an isolated traumatic brain injury (iTBI) and they may be associated with an elevated serum troponin I (TnI) value. However, the influence of an elevated TnI level on CP parameters within the first 24 h after an iTBI is still unknown. The current study was conducted to assess the associations between the initial TnI value on admission and CP parameters during the first 24 h of intensive care unit (ICU) treatment in iTBI patients.
A total of 288 patients with iTBIs, who were admitted to our emergency department between January 2010 and November 2016 were retrospectively analyzed. Blood samples were taken on admission to determine TnI value. Each patient's demographic data, treatment regime, computed tomography results, and intra-hospital outcomes were evaluated, as well as several CP parameters, within the first 24 h of ICU treatment. The entire study population was stratified into patients with an initial TnI elevation (TnI positive) and without an initial TnI elevation (TnI negative).
Increased TnI values on admission were found in 59 (20.5%) patients. There were significant correlations between an initially elevated TnI value and a lower Glasgow Coma Scale score (p = 0.003), higher head Abbreviated Injury Scale score (p<0.0001), and higher Acute Physiology and Chronic Health Evaluation II score (p = 0.005) on admission, as well as a lower Glasgow Outcome Scale score (p = 0.0002) and higher modified Rankin Scale score (p = 0.0001) at discharge. In addition, a significantly higher norepinephrine application rate (NAR) (p<0.0001) and inspiratory oxygen fraction (FiO2) (p = 0.028) were needed in the TnI positive group.
Patients with elevated TnI values on admission require more circulation support (NAR and FiO2) within the first 24 h of ICU treatment after an iTBI. Therefore, the TnI may be a useful biomarker to improve ICU treatment of these patients.
