The presence of a tonic coronary vasoconstriction mediated by the sympathetic nervous system has been demonstrated in conscious and anesthetized dogs during resting and hyperemic conditions. This vasoconstrictor tone could be eliminated by removing the left stellate ganglion and by alpha adrenergic blockade. This study examined the role of alpha receptors on coronary blood flow (CBF) in dogs during submaximal exercise. Eight does were chronically instrumented to measure CBF and left ventricular… CONTINUE READING
