Vessel tone affects transmural distribution of coronary flow during hypoperfusion
Autor: S. Watanabe, C. W. Buffington
Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 268:H1284-H1292
Subendocardial flow is selectively impaired during coronary hypoperfusion. Systolic compression of intramyocardial vessels not only stops capillary flow but empties vessels as well, leading to reversed flow in the arteries that penetrate the myocardi

Left Ventricular Pump Function
Autor: C. W. Buffington
Publikováno v: Update in Intensive Care and Emergency Medicine ISBN: 9783642645129
The heart is a cleverly designed organ that propells blood around the body. Satisfactory performance depends on competent cardiac valves and powerful contraction of cardiac muscle. The heart’s performance is often compared to that of a hydraulic pu

Comparison of myocardial ischemia induced by endothelin vs. mechanical stenosis in pigs
Autor: G. Moresea, C. W. Buffington, S. Watanabe
Publikováno v: The American journal of physiology. 268(3 Pt 2)
We have determined the transmural distribution of myocardial flow and ischemia during endothelin (ET-1) infusion and compared these results with the effects of mechanical stenosis. In anesthetized pigs, coronary flow was reduced 15, 30, and 50% from

Adrenergic coronary vasoconstriction in the presence of coronary stenosis in the dog
Autor: C W Buffington, Eric O. Feigl
Publikováno v: Circulation Research. 48:416-423
Previous studies have demonstrated competition between sympathetic alpha receptor-mediated coronary vasoconstriction and local metabolic vasodilation during sympathetic activation. The present study tested if this competition also occurs in the prese

Parasympathetic control of transmural coronary blood flow in dogs
Autor: A. H. Huang, B. R. Ito, E. O. Feigl, C. W. Buffington, J. V. O. Reid
Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 249:H337-H343
The transmural distribution of coronary blood flow was studied during vagal stimulation in closed-chest, morphine- and alpha-chloralose-anesthetized dogs. The left main coronary artery was cannulated and perfused at constant pressure. Bradycardia dur

Effect of coronary artery pressure on transmural distribution of adrenergic coronary vasoconstriction in the dog
Autor: E O Feigl, C W Buffington
Publikováno v: Circulation Research. 53:613-621
The transmural distribution of alpha-receptor coronary vasoconstriction was studied in 14 closed-chest, morphine- and chloralose-anesthesized dogs. The alpha-receptor-blocking agent, phenoxybenzamine (0.25 mg/kg), was infused into either the anterior
