Stress-induced rearrangement of the myocardium: time course of structural changes in various types of stress.
Common morphological changes in the myocardium were revealed in rats exposed to three different types of stress. At the initial stages of stress, the structural changes were stereotypical (contractures) irrespective of the type of stress factor and differed only by their severity. At later stages contractures were gradually replaced by cytolytic injuries, which did not depend on the type of stress either. Early predominance of myocytolysis in combination with excessive contracture injuries led to rapid death, which is probably a manifestation of genetically determined low capacity to adapt to stress in some individuals.
