[Different flow augmentations in coronary, carotid and renal arteries with ECP in experimental canines]

Different flow augmentations were found in canine's coronary, carotid and renal arteries with ECP because of their different anatomical locations in aorta. We used the Electromagnetic Blood Flowmeters to measure the blood flow pre-ECP and during ECP. The results showed ECP increased the diastolic flow of coronary, carotid and renal arteries by 24.48% +/- 1.29%, 27.18% +/- 0.94% and 20.68% +/- 0.80% respectively, decreased their systolic flow by 4.77% +/- 0.48%, 6.45% +/- 0.99% and 9.60% +/- 0.70%, but augmented their mean flow by 18.24% +/- 2.01%, 19.38% +/- 1.47% and 8.42% +/- 0.94% respectively in experimental dogs. These data demonstrate that ECP can greatly increase the mean flow of coronary and carotid arteries but at the same time patently decrease the systolic flow of renal artery.
