[The comparative analysis of cardiac contractility associated with certain causes of death].

Results of the comparative analysis of structural changes in cardiomyocyte sarcomers revealed by polarization microscopy in certain fatal cases. The main causes of impaired cardiac contractility and cardiac arrest in the victims of craniocerebral injury and in the subjects with acute forms of ischemic heart disease (acute coronary artery insufficiency and acute myocardial infarction in the pre-necrotic phase), pneumonia, or mechanical strangulation asphyxia (resulting from hanging, with the loop placed around the anterior upper third of the neck and the knot in the posterolateral aspect).
