On the mechanisms of ischaemic myocardial lesions.

The examination of the myocardium in 609 natural and violent death cases by using Lie's histochemical method revealed recent ischaemic lesions, extended or microfocal, in 511 cases. These lesions were prevailingly extended in sudden cardiac deaths, alcoholic intoxication and electrocution, while in the various kinds of shock, in asphyxia and pesticide poisoning cases they were of a predominantly microfocal nature. According to these morphological changes, the vascular and metabolic factors involved in producing ischaemic cardiomyopathy are discussed.
