The Inverse Relationship Between Endothelium-Dependent Vasodilation and Blood Pressure is Lost After Cardiopulmonary Bypass

Abstract Cardiopulmonary bypass (CPB) is required for the surgical correction of congenital heart defects and incites an acute inflammatory response that impairs endothelial function post-operatively. Therefore, we hypothesized that the..
