Serotonin receptors in human coronary arteries.
Serotonin (5-hydroxytryptamine, 5-HT) was first identified in serum in 1949 by M. Rapport.' At k that time, the importance of 5-HT was quite modest: The serum vasoconstrictor that appeared when blood was allowed to clot was an important source of artifactual vasoconstriction in investigations aimed at discovering substances possibly causing hypertension. Since then, however, a great interest ha...
متن کاملAtherosclerotic Lesions in Human Coronary Arteries
To investigate the potential role of fluid mechanical factors in the localized genesis and development of atherosclerotic lesions in humans, the exact anatomic locations of atherosclerotic lesions and the flow patterns at such sites in left and right human coronary arteries were studied in detail by flow visualization and high-speed cinemicrographic techniques using five isolated, transparent h...
متن کاملFibrinolytic activity in human atherosclerotic coronary arteries.
The localization of fibrinolytic areas in normal and atheromatous human coronary arteries was studied by the histochemical fibrin slide technique. Fibrinolytic activity was caused by a plasminogen activator. The activator, occasionally observed at sites in the normal endothelial lining, was abundantly present in relation to vessels in the normal adventitia. The pathological adventitia contained...
متن کاملAdrenergic Receptors in Human Atherosclerotic Coronary Arteries
Background—Adrenergic regulation of coronary vasomotion is balanced between 1-adrenergic–mediated ( 1-AR) constriction and 2-adrenergic–mediated ( 2-AR) relaxation. This study aimed at assessing the role of 2-ARs in normal, mildly atherosclerotic, and stenotic human coronary arteries. Methods and Results—During intracoronary (IC) infusion of increasing doses of the 2-AR agonist salbutamol (0.15...
متن کاملRelationship between neointimal thickness and shear stress after Wallstent implantation in human coronary arteries.
BACKGROUND In-stent restenosis by excessive intimal hyperplasia reduces the long-term clinical efficacy of coronary stents. Because shear stress (SS) is related to plaque growth in atherosclerosis, we investigated whether variations in SS distribution are related to variations in neointima formation. METHODS AND RESULTS In 14 patients, at 6-month follow-up after coronary Wallstent implantatio...
