Autonomic Control of Coronary Blood Flowt results in a decrease in coronary blood flow by a local metabolic mechanism. If the heart is electrically paced at a constant rate, then a clear increase in coronary blood flow is observed during parasympathetic activation. Baroreflex parasympathetic cholinergic coronary vasodilation has been demo

Vasoactive Monoamines in the Regulation of Arterial Toneoactive substances, and that the endothelium modulates vasomotor responses to these amines..We examined the effect of serotonin on coronary vasculature and cardiac performance in anesthetized open chest dogs. Without coronary stenosis, intracoronary infusion of serotonin caused concentration-depende

Coronary Vasomotion During Exercise: Influence of the Geometry of Stenosisina pectoris. Luminal areas of 16 normal and 21 stenotic vessel segments were determined by biplane quantitative coronary arteriography at rest, at submaximal exercise, and 5 min after 1.6 mg sublingual nitroglycerin administered at the end of the exercise test. Patients were subdivided (a) into 2 g

Role of Ecto-5′-Nucleotidase on Hypoxia-Induced Adenosine Formation in the Perfused Guinea Pig Heart was examined in the perfused guinea pig heart. EHNA, an adenosine deaminase inhibitor, was used for changing adenosine concentration in the fluid. It was found that there was a good correlation between adenosine concentration in the transmyocardial effluent and the coronary flow. Using the same met

Energy Charge as a Cytosolic Signal for Adenosine Releasey charge. We have used isolated guinea pig and rat hearts to test this hypothesis measuring in vivo high energy phosphate concentrations with .P-NMR. Several different interventions were used to lower energy charge (and phosphorylation potential), including norepinephrine (NE) infusion, hypoperfusio

The Role of Adenosine on Myocardial Reactive Hyperemiaf adenosine during brief coronary occlusions using forskolin and 8-phenyltheophylline (8-PT). We also examined the possible contribution of membrane-bound 5′-nucleotidase to the synthetizing of adenosine. Intracoronary infusion of α, β-methylene adenosine 5-diphosphate (AOPCP) was used for this purp
