[Change n the ploidy classes of left ventricular myocytes in rats after ligation of the left coronary artery].
Heterogeneous response of cardiomyocytes in left atria of rats to ligation of the left coronary artery was observed. Ploidy may greatly increase reaching 32 c per cell. More than 90% of myocytes are normally mononuclear diploid cells, while after the ligation the number of such cells diminishes to 10%. The majority of cells become polyploid: above 50% of cells are 2 X 2 c ploid, about 30% of cells are 4 X 2 c ploid and a great number of cells are highly ploid.
