Cardiac contusion is best described as what?

Explanation:
Cardiac contusion is a bruise to the heart wall caused by blunt chest trauma, with the heart being compressed between the sternum and spine. This injury reflects direct myocardial impact and hemorrhage rather than a tearing, ischemic event, which is what makes it distinct from other cardiac injuries. The alternatives describe different problems: a rupture of the left ventricle is a catastrophic tear after trauma, myocardial infarction results from coronary occlusion and ischemia, and pericardial effusion due to fluid overload is a volume-status issue, not a blunt-trauma bruise of the heart.
