[Regenerative reactions of myocardiocyte nuclei in ischemic heart disease].
The ploidy of myocardiocytes nuclei in the left ventricle was determined stereometrically and microspectrophotometrically in 20 cases of ischemic heart disease (IHD) and 9 control cases. An increase in the number of nuclei and the degree of their ploidy and their correlation with the myocardium mass were established. The number of polyploid nuclei was particularly high in the periphery of postinfarction scars. These data indirectly indicate the participation of polyploidization and amitosis of myocardiocytes nuclei in the development of myocardial regenerative hypertrophy.
