The purpose of this study was to determine whether neuropeptide Y has a direct vasoconstrictor effect at low doses, mimicking the physiological plasma concentration on the specific site(s) of coronary arterial microvessels in in situ beating canine l

The objective of this study was to determine whether coronary vascular resistance remains constant during long diastoles and whether critical closure of arterial microvessels occurs at zero-flow pressure. For this purpose, we directly measured intern

Endocardial pacemaker leads may cause tricuspid valve regurgitation, but only four cases of tricuspid stenosis without endocarditis have been reported. A 77-year-old woman had received three endocardial leads when aged 44, 57, and 72 years. One lead

A 52-year-old man without a history of asthma or allergic diseases died of ventricular fibrillation early in the morning. His autopsy revealed no significant findings, except for a mild mural-thickening localized at the proximal region of the right c

This sudy was carried out to clarify the effects of α- and β-adrenergic blockade on coronary arterial microvessels in beating hearts. For this purpose, we used anesthetized open chest dogs (n = 47). Coronary microcirculation of the epimyocardium wa

Our aim was to elucidate the site and mechanism responsible for reactive hyperemia in coronary circulation. In in vivo beating canine hearts, microvessels of the left anterior descending coronary artery (LAD) were observed through a microscope equipp

Direct and continuous visualization of the coronary microcirculation has been almost impossible in the beating mammalian heart. To achieve this purpose, we have developed a new microscopic system which we termed the “floating objective system”, a

The phasic red cell velocity pattern and the phasic change in diameters in the epimyocardial microvessels were investigated in the beating canine left ventricle. We also studied the effects of nitroglycerin and dilazep, an adenosine potentiator, on t

We investigated whether the relationship between the mean left anterior descending and septal coronary blood flow and the mean perfusion pressure varies with left circumflex coronary stenosis. We used excised, perfused canine heart preparations (n =

To examine how end systole differs from end ejection and also whether the slope of the end systolic pressure-volume relation can be approximated to that of the end ejection pressure-volume relation, nine isolated, perfused, paced canine hearts ejecti
