Blunt-chest-trauma-induced acute myocardial infarction

Abstract

Blunt chest trauma (BCT) is one of the rarest causes of acute myocardial infarction (AMI). This paper reports the case of a young married man who suffered from AMI due to BCT sustained in a fight with his wife. The histopathology examination revealed a rupture of atherosclerotic plaque with superimposed thrombus in the proximal left anterior descending artery. This report also reviews previously reported BCT-induced AMI cases in the literature.

“…Several case reports have been published associating acute myocardial infarction to chest trauma secondary to aortic dissection or a preexisting aortic aneurysm [3,4]. Furthermore Kumar, et al reported a case of young healthy male that deceased after sustaining a blunt chest trauma (BCI) and on autopsy was found to have a thrombus in the proximal LAD attributing it to a rupture of a plaque secondary to the BCI [5]. To the authors knowledge, this article is the first to report a case of a young male sustaining an acute myocardial infarction requiring stenting with no underlying aortic dissection or aortic aneurysm secondary to a BCI.…”

ST-elevation Myocardial Infarction Indirectly Induced by Trauma

“…An arterial blood gas analysis revealed the following: pH Blunt chest trauma can be a direct cause of acute MI 2) . The left anterior descending coronary artery is most likely to be affected in this condition 2,4) probably because of its anatomical po-sition. However, in the present case, there was no evidence of direct traumatic injury to the heart (e.g., pericardial effusion or avulsion of cardiac valves).…”

<i>Commotio mortis</i>. Infarto agudo de miocardio secundario a contusión de tórax, un ejemplo poco común de infarto tipo 1

“…La incidencia ha aumentado debido a un cambio en el patrón de accidentes automovilísticos y otras colisiones 1 . Aunque es poco común, es uno de los mecanismos no ateroscleróticos que conducen al infarto agudo de miocardio en pacientes jóvenes, a menudo sin antecedentes clínicos de enfermedad cardiaca 2 . Las consecuencias de una lesión cardiovascular, como la rotura del tabique o de la pared de la cámara del miocardio y la trombosis de la arteria coronaria principal son importantes 3 .…”
