THE MYOCARDIAL CAPILLARY VASCULATURE IN EXERCISING ANIMALS WITH INCREASED CARDIAC PRESSURE LOAD

Abstract
The myocardial capillary reaction was studied in normal rats subjected to swimming exercise and in rats which aortic stenosis was produced at various time intervals before the swimming exercise was commenced. Neoformation of myocardial capillaries during swimming exercise occurred only in rats without aortic stenosis. A heart subjected to an increased pressure load is less able to respond to a superimposed volume load by an increase in its capillary supply than is a normal heart.
