Summary
Cardiac dysfunction is common after traumatic brain injury (TBI) and linked to higher mortality. Early detection and hemodynamic management may improve outcomes for TBI patients.
Area of Science:
- Cardiology
- Neurology
- Trauma Surgery
Background:
- Traumatic brain injury (TBI) can lead to significant physiological disturbances.
- Cardiac dysfunction following TBI is not well understood.
- Understanding cardiac complications is crucial for managing TBI patients.
Purpose of the Study:
- To investigate the occurrence of cardiac dysfunction within two weeks of isolated TBI.
- To determine the association between cardiac dysfunction and in-hospital mortality in TBI patients.
Main Methods:
- Retrospective analysis of adult patients with isolated TBI.
- Echocardiography performed within 14 days of injury.
- Cardiac dysfunction defined by reduced ejection fraction or regional wall motion abnormalities.
- Exclusion of patients with pre-existing cardiac disease.
Main Results:
- 22.3% of TBI patients exhibited cardiac dysfunction.
- Reduced left ventricular ejection fraction (LVEF < 50%) occurred in 12%.
- Regional wall motion abnormalities were present in 17.5% of patients.
- Abnormal echocardiograms were independently associated with increased in-hospital mortality (OR 9.6, p=0.002).
Conclusions:
- Cardiac dysfunction is a significant complication after isolated TBI.
- The presence of cardiac dysfunction correlates with higher in-hospital mortality.
- Timely recognition and hemodynamic optimization may improve TBI patient outcomes.
