Traumatic myocardial infarction can occur in young adults due to chest trauma. These cases highlight distinct mechanisms, including myocardial contusion and coronary artery injury, leading to varied outcomes and management challenges.

Area of Science:

Cardiology
Trauma Surgery
Pathology

Background:

Traumatic myocardial infarction is a rare but serious condition.
Understanding its pathophysiology is crucial for diagnosis and treatment.

Observation:

Reported are two cases of young patients (18 and 19 years) experiencing myocardial infarction following closed chest trauma.
Case 1: Myocardial contusion with subendocardial tear after thoraco-abdominal crushing trauma, resulting in a favorable outcome.
Case 2: Transmural myocardial infarction secondary to coronary artery adventitial tear, leading to an antero-apical aneurysm.

Findings:

The cases illustrate two distinct physiopathological mechanisms of traumatic myocardial infarction.
Spontaneous recovery was observed in myocardial contusion, while coronary artery lesion required surgical intervention (infarctectomy and aorto coronary bypass).

Implications:

These cases underscore the importance of considering myocardial infarction in young individuals with chest trauma.
The findings emphasize the need for thorough diagnostic evaluation and tailored therapeutic strategies.
Discussion includes diagnostic, therapeutic, and medicolegal considerations for traumatic myocardial infarction.
