Direct and reflex effects of nitroglycerin on coronary and left ventricular dynamics in conscious dogs.
The effects of intravenous and sublingual glyceryl trinitrate (nitroglycerin), 40 mug/kg, were studied on coronary blood flow and resistance, left ventricular (LV) pressures (P) and diameters (D), rate of change of pressure (dP/dt), (dP/dt)/P, and on the velocity (V) of myocardial fiber shortening in conscious dogs. Nitroglycerin i.v. caused substantial coronary vasodilatation prior to any chan...
متن کاملReflex vascular responses to left ventricular outflow obstruction and activation of ventricular baroreceptors in dogs.
Reflex vascular responses to acute left ventricular outflow obstruction were studied in anesthetized dogs. The studies were done to compare the effects of activation of ventricular baroreceptors on vascular resistance in skeletal muscle (gracilis muscle) and skin (hindpaw); to identify afferent and efferent pathways which mediate the reflex vasodilatation; and to assess the relative contributio...
متن کاملHindlimb venous distention evokes a pressor reflex in decerebrated rats
The distention of small vessels caused by an increase in blood flow to dynamically exercising muscles has been proposed as a stimulus that activates the thin fiber (groups III and IV) afferents evoking the exercise pressor reflex. This theory has been supported by evidence obtained from both humans and animals. In decerebrated unanesthetized rats with either freely perfused femoral arteries or ...
متن کاملEffects of left ventricular assist device therapy on ventricular arrhythmias.
OBJECTIVES In a retrospective study, we sought to evaluate the effect of left ventricular assist device (LVAD) therapy on ventricular tachyarrhythmias in patients with advanced congestive heart failure. BACKGROUND Despite the increasing use of LVAD as a bridge to cardiac transplantation, our knowledge regarding its effect on ventricular arrhythmias is currently limited to small series. Little...
متن کاملHigh myocardial 18F-FDG uptake after chemotherapy in the presence of left ventricular dysfunction as well as 3-month later with no left ventricular dysfunction
Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...
