Carotid sinus baroreceptor control of right coronary circulation in normal, hypertrophied, and failing right ventricles of conscious dogs.
Tlie right coronary vascular response to bilateral carotid occlusion (BCO) was assessed in normal, conscious dogs and also in dogs with right ventricular (RV) hypertrophy alone or in combination with right heart failure, induced by chronic (5-7 months) pulmonary artery stenosis. In normal, conscious dogs with intact adrenergic neural activity and with heart rate held constant by electrical paci...

15 صفحه اولLoad-sensitive diastolic relaxation in hypertrophied left ventricles.
We studied effects of enalaprilat and L-158,809, an angiotensin II type-1 receptor antagonist, on left ventricular (LV) diastolic relaxation in 11 normal control dogs and 16 LV hypertrophied (LVH) dogs with perinephritic hypertension. At baseline, LV systolic and end-diastolic pressures and end-systolic elastance were increased in the LVH group (all P < 0.01 vs. the control group). LV relaxatio...
متن کاملFractional contributions of the right and left coronary arteries to perfusion of normal and hypertrophied right ventricles of conscious dogs.
The extent to which the blood supply of normal and hypertrophied right ventricles originates from the right and left coronary arteries was investigated in conscious dogs. Right ventricular (RV) hypertrophy, induced by gradual, chronic (4-6 months) stenosis of the main pulmonary artery, was characterized by a 72% increase (P < 0.001) in RV weight to body weight ratio and a 106% increase (P < 0.0...
