TORRES SANCHEZ, C. et al. Myocardial histopathology in the closed chest trauma. Cuad. med. forense [online]. 2002, n.27, pp.53-59. ISSN 1988-611X.

In the present paper, we studied the histological findings in different causes of death, in order to confirm that the myocardial histological pathology could reflect the process that determine the death, in relation to the nature of the agonic suffering (ischemic and/or anoxic and localized or generalized). We have studied 59 cadavers, 43 males and 16 females, of which 40 died for traumatic causes and other 19 for no traumatic causes. Their ages were between 17 and 90 years old, with an average age of 51,33 years, and the mean postmortem was 13,6 hours (SD 8,7; range 3-59 hours). For this histopathology work, we obtained samples of cardiac tissues from the apex, anterior, lateral and posterior side of the left ventricle, lateral side of the right ventricle and middle side of the interventricle wall, in two different levels of the heart. After fixing and processing of the samples, staining with hematoxylin-eosin and orange acridine were performed. The statistical analysis was carried out using SPSS 10.0. Our results showed the usefulness of hematoxylin-eosin staining for detect the previous myocardial afectation and cronic illness, in the other hand the acridine orange is most usseful to detect ischemic lesions in these locations where the processes of perfusion of the cardiac muscle are going to be more affected acording the previous bibliography.
