Lack of significant long-term sequelae following traumatic myocardial contusion
Insights
Traumatic myocardial contusion, or heart bruising, typically resolves within one year. Patients with heart bruising showed no long-term functional cardiac sequelae compared to those without.
Area of Science:
- Cardiology
- Trauma Surgery
- Cardiac Imaging
Background:
- Traumatic myocardial contusion is a cardiac injury resulting from blunt chest trauma.
- The potential for long-term functional cardiac sequelae following myocardial contusion requires thorough investigation.
Purpose of the Study:
- To evaluate the long-term functional cardiac outcomes in patients with traumatic myocardial contusion.
- To compare cardiac function in patients with myocardial contusion versus those with similar trauma but without cardiac involvement.
Main Methods:
- Prospective cohort study comparing patients with traumatic myocardial contusion (group 1) to a control group with similar trauma but no cardiac injury (group 2).
- Assessment included New York Heart Association (NYHA) classification and left and right ventricular ejection fractions (LVEF and RVEF) at rest and during maximal exercise at follow-up.
- Follow-up evaluation was conducted more than one year post-injury.
Main Results:
- At over one year post-injury, patients in both groups were qualitatively similar based on NYHA classification.
- While LVEF and RVEF were initially lower in group 1 immediately post-trauma, they became similar between groups at rest during follow-up.
- Changes in mean LVEF and RVEF during maximal exercise were also similar between the groups at follow-up.
Conclusions:
- Traumatic myocardial contusion, affecting either the left or right ventricle, generally resolves without significant long-term functional cardiac sequelae.
- Cardiac function, assessed by ejection fractions and exercise capacity, returns to baseline levels within one year post-injury in most patients.
Abstract:
We assessed the possibility of long-term functional cardiac sequelae in patients who had sustained a traumatic myocardial contusion (group 1) by comparing this group with a cohort group of patients with similar traumatic injuries but exclusive of the cardiac component (group 2). More than one year following injury, patients in group 1 were qualitatively indistinguishable from patients in group 2 according to the New York Heart Association classification. Both the left and the right ventricular ejection fractions, less in group 1 than in group 2 immediately following trauma, were similar between groups during follow-up study at rest. During exercise to maximal work load at follow-up, changes in the mean right and left ventricular ejection fractions were also similar between the two patient groups. We therefore concluded that traumatic myocardial contusion to the left and/or right ventricle almost always resolves without significant functional sequelae within one year of injury.
