title: [The pathomorphology and pathogenesis of acute cardiovascular failure in swine. 1. Histopathologic findings in the myocardium of swine of different age groups].
abstract: Myocardia were histologically examined for the presence of pathomorphological processes in 143 pigs of varying age groups (one, three, seven to nine, and 24 months). Some of them had been slaughtered in clinically intact condition. Others had died of non-cardial diseases. Numerous alterations were recorded, with the following among them being more suitable than others for quantitative assessment and thus objective appraisal of the myocardium: inflammatory infiltrations, granular or hyaline disintegration of fibres, fibre necrosis, dystrophic calcification of fibres, degenerative fat infiltration, and sarcosporidiosis. These parameters were increasingly detectable along with growing age of animals. Inflammatory infiltrations were among the most common findings from pigs for slaughter, aged seven to nine months (40.4 percent of myocardial samples or 58 percent of hearts), followed by muscle fibre necroses (26.4 or 42.0 percent). Most of these disorders were but slightly manifest and were considered to be indicators of catabolic or reparative processes in the myocardium. Attention should be given to them, whenever it comes to pigs with cardiac or circulatory disturbances.
