Alpha-adrenoceptor blockade prevents exercise-induced vasoconstriction of stenotic coronary arteries.
OBJECTIVES The study aimed to evaluate the role of alpha-adrenergic mechanisms during dynamic exercise in both normal and stenotic coronary arteries. BACKGROUND Paradoxical vasoconstriction of stenotic coronary arteries has been reported during dynamic exercise and may be due to several factors such as alpha-adrenergic drive, a decreased release of nitric oxide, platelet aggregation with rele...
متن کاملSegmental alpha-receptor-mediated vasoconstriction in the canine coronary circulation.
Recent studies from this laboratory have indicated that sympathetic alpha-receptor-mediated coronary vasoconstriction can compete with local metabolic vasodilation to reduce the oxygen supply to the myocardium. In vitro studies from other laboratories on isolated coronary vessel strips suggest that large epicardial vessels are the dominant site of adrenergic alpha-receptor activity. In this stu...
متن کاملAlpha adrenergic vasoconstriction and nitroglycerin vasodilation of large coronary arteries in the conscious dog.
The effects of methoxamine and nitroglycerin on measurements of large vessel (left circumflex) coronary dimensions were examined in eight conscious dogs using an ultrasonic dimension gauge, and total coronary resistance was calculated from measurements of arterial pressure and coronary blood flow. Methoxamine (50 mug/kg per min), after transiently increasing left circumflex coronary dimensions,...
متن کاملRegional differences of responses to adrenoceptor agonists in isolated and perfused canine coronary arteries.
Regional differences of the responses to adrenoceptor agonists were investigated in isolated canine coronary arteries by use of a cannula inserting method. Acetylcholine induced a dose-dependent vasodilation. Norepinephrine and epinephrine produced a vasoconstriction followed by a strong vasodilation in large coronary arteries and only a weak vasodilation in small coronary arteries. Phenylephri...
متن کاملEffect of intravenous propranolol on coronary vasomotion at rest and during dynamic exercise in patients with coronary artery disease.
Coronary vasomotion was studied at rest and during bicycle exercise with biplane quantitative coronary arteriography in 28 patients with coronary artery disease. Patients were divided into two groups; the first 18 patients served as controls (group 1), and the next 10 patients were treated with propranolol 0.1 mg/kg, which was infused intravenously before exercise (group 2). Luminal area of a n...
