Arteriovenous anastomoses disrupt cardiovascular and renal homeostasis, eliciting hemodynamic adjustments, resetting the humoral pattern, and inducing cardiac hypertrophy. Because acute circulatory imbalance alters gut motor behavior, we studied the effects of arteriovenous fistula placement on the gastric emptying (GE) of a liquid meal in awake rats. After laparotomy, we created an aortocaval ...
Studies were performed to determine whether the intrarenal distribution of cortical blood flow is altered in congestive heart failure. Utilizing the radioactive microsphere method, we studied eight dogs that developed congestive heart failure secondary to the construction of an aortocaval fistula. They had marked reduction in total renal blood flow not accompanied by intracortical redistributio...
Background Besides cardiac load, the renin-angiotensin system (RAS) and aldosterone may regulate collagen accumulation during maturation or hypertrophic growth. The effect of cardiac volume overload on both left ventricular (LV) and right ventricular (RV) collagen and elastin and the possible role of the RAS in such changes have not yet been assessed. Methods and Results In the present study we...
