Coronary collateral blood flow was measured in 7 miniature pigs, exercise trained (ET) for 10 mo by running about 35 km/wk, and in 10 sedentary control pigs (SC). In acute, open-chest preparations, radiolabeled (85SR, 141CE, or 51Cr) microspheres, 15 +/- 5 micron in diameter, were injected into the left atrium during each of three conditions: control (C), total occlusion of the left circumflex artery (TO), and TO plus mechanically elevated aortic pressure (TOP). Blood flow to the circumflex bed during control condition in ET and SC was 0.36 +/- 0.07 (SE) and 0.43 +/- 0.10 ml.g-1.min-1, respectively. During TO, circumflex flow in ET and SC fell to 0.05 +/- 0.01 and 0.06 +/- 0.01 ml.g-1.min-1, respectively. In the presence of TOP, left circumflex flow in ET and SC rose to 0.11 +/- 0.04 and 0.11 +/- 0.02 ml.g-1.min-1, respectively. Blood flow to the tissue bed of the left anterior descendens was the same in both groups of pigs under all conditions. Thus, 10 mo of endurance exercise training seems to have no effect on the development of coronary collaterals in the left ventricles of pig hearts.
