The medicolegal importance of ischaemic heart disease and myocardial infarction is summarized and discussed. Some theories of pathogenesis and aetiology of ischaemic heart disease, specially those which are more important and relevant to the medicolegal practice, are discussed. Results of the study of 33 cases of coronary artery atherosclerosis and myocardial infarction at different stages of development are presented. The condition of the coronary arteries and the myocardium is examined on gross and microscopical levels. Pathological findings are correlated with the clinical data obtained from the case histories and the summaries of the necropsy requests. No good correlation exists between the observed pathological changes and the clinical age of the infarction and, in most instances, the latter appears younger than the age estimated on the pathological ground alone. As far as the age of the infarction is concerned, most special histochemical staining methods are not preferable to the routine haematoxylin and eosin method. However, the former are efficient in demonstrating and confirming certain aspects of the infarction which cannot be ascertained by the latter method of staining. Pathological alterations associated with myocardial infarction at successive ages are explained and various methods of estimating the time of the infarction are discussed. Thus, gross and microscopical appearances of the acute, organizing and healed myocardial infarction are illustrated by photographs and the forensic applications of these morphological changes are discussed. Lastly, a rare case of an acute myocardial infarction associated with a heat stroke is presented and the medicolegal problems resulting from this case are discussed.

Myocardial Lesions

The pathogenesis of the arteriosclerosis in the acute myocardial infarction is the matter of the extensive survey with the transmission electron microscopy in experimental and clinical materials. In the previous communication,the authors have clarified that the two types of the coronary vascular changes could exist. The first category is the case in which we had failed to observe no occlusive changes of the coronary vessels which eventually form the myocardial infarction. The next category is the case in which occlusive -thrombotic changes are observed in which the myocardial infarction will be taken placed as the final event. The authors incline to designate the former category as the non-occlusive-non thrombotic lesions. The most important findings in both cases are the “mechanical destruction of the vascular wall and imbibition of the serous component” which are most frequently observed at the proximal portion of the coronary main trunk.
