Myocardial hypertrophy: the distribution of cell growth within the layers of the myocardium.
The spatial distribution of radioactively labeled microspheres was studied in normal and in experimentally hypertrophied hearts of adult pigs. The hearts had been "tagged" with microspheres when the pigs were young. When the adult animal was killed, the spatial distribution of the microspheres was identical in the normal and in the hypertrophied hearts. This demonstrates that hypertrophic growth had occurred evenly throughout all layers of the myocardium.
