What condition should raise suspicion of myocardial contusion in a patient with a bent steering wheel?

Myocardial contusion is an injury to the heart muscle typically resulting from blunt force trauma, such as that experienced in a motor vehicle collision when a person strikes the steering wheel. A bent steering wheel indicates significant impact and raises the likelihood of a chest injury, including a possible myocardial contusion.

The absence of other major signs or symptoms may raise suspicion of myocardial contusion because it may not present with the hallmark symptoms one might expect from more severe thoracic injuries. In cases where a patient appears stable with minimal presenting symptoms following a significant impact, clinicians must be vigilant; the lack of outward manifestations does not rule out the potential for serious internal injuries, particularly to the heart.

This consideration highlights the importance of a high index of suspicion, as myocardial contusions can sometimes be insidious and may not exhibit dramatic signs immediately after injury. Consequently, it necessitates further investigation, such as ECG or cardiac biomarkers, to rule out or confirm the presence of an injury to the cardiac muscle.
