Non-uniform myocardial blood flow caused by stellate ganglion stimulation. 1975

Y Uchida, and H Ueda

The blood flow through the anterior wall of the left ventricle has been studied during electrical stimulation of the left stellate ganglion of anesthetized dogs. The flow was continuously monitored by heated cross-thermocuple. Ganglion stimulation caused a significant increase in the flow through the outer half while producing relative ischemia of the inner half of the wall. Pretreatment with propranolol reduced regional difference of flow changes. Significantly augmented non-uniform flow changes, however, were produced by ganglion stimulation during hypertension caused by aortic constriction or by methoxamine. The results indicate non-uniform blood flow distribution which can be produced by sympathetic nerve excitation.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D008729 Methoxamine An alpha-1 adrenergic agonist that causes prolonged peripheral VASOCONSTRICTION. Methoxamedrin,Methoxamine Hydrochloride,Metoxamine Wellcome,Vasoxin,Vasoxine,Vasoxyl,Vasylox,Hydrochloride, Methoxamine,Wellcome, Metoxamine
D011433 Propranolol A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.

D003326 Coronary Circulation The circulation of blood through the CORONARY VESSELS of the HEART. Circulation, Coronary
D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
