Serotonin as a mediator of cyclic flow variations in stenosed canine coronary arteries.
The data obtained in this study demonstrate that the concentration of serotonin is markedly elevated (18- to 27-fold) at the site of a coronary arterial stenosis in open-chest, anesthetized dogs withExpand
Extensive Myocardial Fiber Disarray in Aortic and Pulmonary Atresia: Relevance to Hypertrophic Cardiomyopathy
Myocardial fiber disarray is a distinctive histopathologic finding seen in asymmetric hypertrophic cardiomyopathy. We studied 14 hearts with aortic atresia and intact interventricular septum, sixExpand
Local platelet activation causes vasoconstriction of large epicardial canine coronary arteries in vivo. Thromboxane A2 and serotonin are possible mediators.
The goal of the present study was to demonstrate that intracoronary platelet deposition may trigger intense vasoconstriction of large epicardial coronary arteries in vivo and that this is largelyExpand
Race and the decision to refer for coronary revascularization: the effect of physician awareness of patient ethnicity.
OBJECTIVES We sought to assess whether there were differences, relative to racial ethnicity, in coronary revascularization recommendations made by a panel that had no knowledge of the patients'Expand
Artifactual regional gray level variability in contrast-enhanced two-dimensional echocardiographic images: effect on measurement of the coronary perfusion bed.
The purpose of this study was to determine the extent of regional variability of image echocardiographic amplitude (expressed as gray level variability) in contrast-enhanced two-dimensionalExpand
Relationship between 24-H blood pressure and sleep disordered breathing in a normotensive community sample.
Sleep disordered breathing (SDB) and hypertension are commonly associated. In this study, we assessed how longitudinal measures of SDB predict a 24-h ambulatory blood pressure monitoring (ABPM)Expand
Intracardiac thrombus causing peritoneovenous shunt failure: detection by two-dimensional echocardiography.
Peritoneovenous shunts have become an accepted mode of therapy for ascites refractory to medical treatment. However, their use is known to be associated with significant morbidity and mortality.Expand
Can β-Hydroxybutyrate Be Detected at the Bedside by In Vitro Oxidation with Hydrogen Peroxide?
The diagnosis of ketoacidosis with an inordinately high plasma and urinary concentration ratio of β-hydroxybutyrate (β-OHB) to acetoacetate (AcAc) is difficult, because only AcAc and acetone reactExpand
Corticotropin-releasing hormone.
THAT both neural and hormonal changes play a part in the adaptive responses of complex organisms to physical or psychological challenges has been appreciated for well over a century. In 1948, Harris1Expand
Inhibition of Cyclic Flow Variations in Stenosed Canine Coronary Arteries by Thromboxane A2/Prostaglandin H2 Receptor Antagonists
We tested the hypothesis that thromboxane A2 and thromboxane A2/PGH2 receptor occupation are important in mediating cyclical reductions in coronary blood flow (CFVs) in concentrically narrowed canineExpand
