Traumatic myocardial infarction with subsequent normal coronary arteriogram

Area of Science:

• Cardiology
• Sports Medicine
• Trauma Research

Background:

• Myocardial infarction (MI) is typically associated with atherosclerosis.
• Blunt chest trauma can precipitate cardiac events, but direct coronary artery injury is rare.

Observation:

• A 36-year-old male experienced transmural anterior myocardial infarction shortly after direct chest impact from a football.
• No external chest wall trauma or fractures were noted.
• Coronary angiography revealed no significant vessel obstruction six weeks post-event.

Findings:

• The clinical presentation suggests a non-atherosclerotic cause for myocardial infarction.
• Suspected diagnoses include coronary artery injury with transient thrombosis and recanalization, myocardial contusion, or coronary artery spasm.
• The absence of visible obstruction points to a dynamic or resolved process.

Implications:

• Highlights the potential for sudden cardiac events following seemingly minor chest trauma.
• Emphasizes the need to consider coronary artery injury and spasm in young individuals presenting with MI post-trauma.
• Suggests further investigation into the mechanisms of traumatic cardiac injury and its management.
