Acute Myocardial Dysfunction and Chest Trauma - The Strainy Trauma Study

This study aims to investigate whether the identification of acute myocardial dysfunction by 2D-strain transthoracic sonography in the first week following trauma would allow to better diagnose occult and severe patterns of myocardial contusion, in order to identify a subpopulation at higher risk of complications. The measurement of myocardial strain (2D-strain) by transthoracic sonography is a robust tool to assess the myocardial function. The investigators strongly suppose that the 2D-strain would allow to better identify subclinical MC in chest trauma, as well as the severe patterns that are associated with more organs dysfunctions and a worst outcome.
